5 Basic Operations  
5.1 Get Familiar with Voice Prompt  
HandyTone-496 stores a voice prompt menu (Interactive Voice Response or IVR) for quick browsing  
and simple configuration. Currently, the voice prompt menu and the LED button are designed for FXS  
port 1 only.  
To enter this voice prompt menu, simply pick up the phone and press the button on the HandyTone-  
496 or pick up the phone and dial “***”. The following table shows how to use the voice prompt menu  
to configure the device.

Enter “#” to return to the main menu  
Enter 01-06, 47, 86, 99 menu option  
Enter “9” to toggle the selection  
If user selects “Static IP Mode”, user need  
configure the all IP address information  
through menu 02 to 05. If user selects  
“Dynamic IP Mode”, the device will retrieve  
all IP address information from DHCP server  
automatically when user reboots the device.

HandyTone-496 User Manual  
Grandstream Networks, Inc.  
Once the button is pressed, it enters the voice prompt main menu. If the button is pressed again,  
while it is already in the voice prompt menu, it jumps to “Direct IP Call” option and a dial  
tone is prompted  
“*” shifts down to the next menu option  
“#” returns to the main menu  
“9” functions as the ENTER key in many cases to confirm an option  
All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP  
address. Once all of the digits are collected, the input will be processed.  
Key entry can not be deleted but the phone may prompt error once it is detected  
5.2 Make Phone Calls  
5.2.1 Calling Phone or Extension Numbers  
To make a phone or extension number call:  
a) Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”). Or  
b) Dial the number directly, and press # (assuming that “Use # as dial key” is selected in web  
configuration).  
Examples:  
To dial another extension on the same proxy, such as 1008, simply pick up the attached phone,  
dial 1008 and then press the # or wait for 4 seconds.  
To dial a PSTN number such as 6266667890, you might need to enter in some prefix number  
followed by the phone number. Please check with your VoIP service provider to get the information. If  
you phone is assigned with a PSTN-like number such as 6265556789, most likely you just follow the  
rule to dial 16266667890 as if you were calling from a regular analog phone, followed by pressing #  
or wait for 4 seconds.  
5.2.2 Direct IP Calls  
Direct IP calling allows two parties, that is, a HandyTone with an analog phone and another VoIP  
Device, to talk to each other in an ad hoc fashion without a SIP proxy. This kind of VoIP calls can be  
made between two parties if:  
Both HandyTone ATA and other VoIP Device(i.e., another HandyTone ATA or Budgetone SIP  
phone or other VoIP unit) have public IP addresses, or  
Both HandyTone ATA and other VoIP Device are on the same LAN using private IP addresses,  
or  
Both HandyTone ATA and other VoIP Device can be connected through a router using public  
or private IP addresses (with necessary port forwarding or DMZ).  
11  
 
HandyTone-496 User Manual  
Grandstream Networks, Inc.  
To make a direct IP call, first pick up the analog phone or turn on the speakerphone on the analog  
phone, then access the voice menu prompt by dial “***” or press the button on the HandyTone-496,  
and dials “47” to access the direct IP call menu. User will hear a voice prompt “Direct IP Calling” and  
a dial tone. Enter a 12-digit target IP address to make a call. Destination ports can be specified by  
using “*4” (encoding for “:”) followed by the port number.  
Examples:  
If the target IP address is 192.168.0.160, the dialing convention is  
Voice Prompt with option 47, then 192168000160  
followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the  
default destination port 5060 is used if no port is specified.  
If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:  
Voice Prompt with option 47, then 192168001020*45062 followed by pressing the “#” key if it is  
configured as a send key or wait for 4 seconds.  
5.2.3 Call Hold  
While in conversation, pressing the “flash” button on the attached phone will put the remote end on  
hold. Pressing the “flash” button again will release the previously held party and the bi-directional  
media will resume.  
5.2.4 Call Waiting  
If call waiting feature is enabled, while the user is in a conversation, he will hear a special stutter tone  
if there is another incoming call. User can press the flash button to put the current call party on hold  
and switch to the other call. Pressing flash button toggles between two active calls.  
5.2.5 Call Transfer  
5.2.5.1 Blind Transfer  
Assuming that call party A and B are in conversation. A wants to Blind Transfer B to C:  
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial  
tone.  
2. Then A dials *87 then dials C’s number, and then #(or wait for 4 seconds)  
3. A can hang up.  
NOTE: Enable Call Feature” has to be set to “Yes” in web configuration page.  
12  
 
HandyTone-496 User Manual  
Grandstream Networks, Inc.  
A can hold on to the phone and wait for one of the three following behaviors:  
A quick confirmation tone (temporarily using the call waiting indication tone) followed by a  
dial tone. This indicates the transfer is successful (transferee has received a 200 OK from  
transfer target). At this point, A can either hang up or make another call.  
A quick busy tone followed by a restored call (on supported platforms only). This means the  
transferee has received a 4xx response for the INVITE and we will try to recover the call. The  
busy tone is just to indicate to the transferor that the transfer has failed.  
Busy tone keeps playing. This means we have failed to receive the second NOTIFY from the  
transferee and decided to time out. Note: this does not indicate the transfer has been  
successful, nor does it indicate the transfer has failed. When transferee is a client that does not  
support the second NOTIFY (such as our own earlier firmware), this will be the case. In bad  
network scenarios, this could also happen, although the transfer may have been completed  
successfully.  
5.2.5.2 Attended Transfer  
Assuming that call party A and B are in conversation. A wants to Attend Transfer B to C:  
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone  
2. A then dial C’s number then # (or wait for 4 seconds).  
3. If C answers the call, A and C are in conversation. Then A can hang up to complete transfer.  
4. If C does not answer the call, A can press “flash” back to talk to B.  
NOTE:  
When Attended Transfer failed, if A hangs up, the HandTone-496 will ring user A again to  
remind A that B is still on the call. A can pick up the phone to restore conversation with B.  
5.2.6 3-way Conferencing  
HandyTone-496 supports 3-way conference in two styles: star code style or Bellcore style.  
5.2.6.1 Star Code Style 3-way Conference  
Assuming that call party A and B are in conversation. A wants to bring C in a conference:  
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial  
tone.  
2. A dials *23 then C’s number then # (or wait for 4 seconds).  
3. If C answers the call, then A press “flash” to bring B, C in the conference.  
4. If C does not answer the call, A can press “flash” back to talk to B.  
13  
 
HandyTone-496 User Manual  
Grandstream Networks, Inc.  
5.2.6.2 Bellcore Style 3-way Conference  
Bellcore style 3-way conference is also supported. To do this, user needs to enable “Use Bell-style 3-  
way Conference” in FXS1 or FXS2 web configuration.  
Assuming that call party A and B are in conversation. A wants to bring C in a conference:  
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial  
tone.  
2. A dials C’s number then # (or wait for 4 seconds).  
3. If C answers the call, then A press “flash” to bring B, C in the conference.  
4. If C does not answer the call, A can press “flash” back to talk to B.

5.4 Fax  
HandyTone-496 supports FAX in two modes: T.38 (Fax over IP) and fax pass through. T.38 is the  
preferred method because it is more reliable and works well in most network conditions. If the service  
provider supports T.38, please use this method by selecting Fax mode to be T.38. If the service  
provider does not support T.38, pass-through mode may be used. To send or receive faxes in fax pass  
through mode, user is recommended to select all the Preferred Codecs to be PCMU/PCMA.

This contains the password to access the Web Configuration Menu. This  
field is case sensitive.  
Web Port  
This is the device’s internal HTTP server port. Default is 80.  
There are 2 modes under which the HandyTone ATA can operate:  
IP Address  
- If DHCP mode is enabled, then all the field values for the Static IP mode  
are not used (even though they are still saved in the Flash memory.) The  
HandyTone ATA will acquire its IP address from the first DHCP server it  
discovers from the LAN it is connected.  
To use the PPPoE feature the PPPoE account settings need to be set. The  
HandyTone will attempt to establish a PPPoE session if any of the PPPoE  
fields is set.  
- If Static IP mode is enabled, then the IP address, Subnet Mask, Default  
Router IP address, DNS Server 1 (primary), DNS Server 2 (secondary) fields  
will need to be configured. These fields are reset to zero by default.  
DHCP hostname  
DHCP domain

Time Zone  
This parameter controls how the displayed date/time will be adjusted  
according to the specified time zone.  
Daylight Savings Time This parameter controls whether the displayed time will be daylight savings  
time or not. If set to “Yes” and the Optional Rule is empty, then the  
displayed time will be 1 hour ahead of normal time.  
The “Automatic Daylight Saving Time Rule” shall have the following  
syntax:  
start-time;end-time;saving  
Both  
start-time  
and  
end-time  
have  
the  
same  
syntax:  
month,day,weekday,hour,minute  
month: 1,2,3,..,12 (for Jan, Feb, .., Dec)  
day: [+|-]1,2,3,..,31  
weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 which means the daylight  
saving rule is not based on week days but based on the day of the month.  
hour: hour (0-23),  
minute: minute (0-59)  
If “weekday” is 0, it means the date to start or end daylight saving is at  
exactly the given date. In that case, the “day” value must not be negative. If  
“weekday” is not zero and “day” is positive, then the daylight saving starts  
on the first “day”th iteration of the weekday (1st Sunday, 3rd Tuesday etc).  
If “weekday” us not zero and “day” is negative, then the daylight saving  
starts on the last “day”th iteration of the weekday (last Sunday, 3rd last  
Tuesday etc).  
The saving is in the unit of minutes. The saving time may also be preceded  
by a negative (-) sign if subtraction is desired instead of addition.  
The default value for “Automatic Daylight Saving Time Rule” shall be set to  
“04,01,7,02,00;10,-1,7,02,00;60” which is the rule for US.  
Examples  
US/Canada where daylight saving time is applicable:  
04,01,7,02,00;10,-1,7,02,00;60  
This means the daylight saving time starts from the first Sunday of April at  
2AM and ends the last Sunday of October at 2AM. The saving is 60 minutes  
(1hour).

SIP and RTP ports. This is usually necessary when multiple HandyTone ATAs  
are behind the same NAT.  
DTMF Payload  
Type  
This parameter sets the payload type for DTMF using RFC2833.  
Send DTMF  
This parameter specifies the mechanism to transmit DTMF digit. There are 3  
modes supported: in audio which means DTMF is combined in audio signal  
(not very reliable with low-bit-rate codec), via RTP (RFC2833), or via SIP  
INFO. Multiple selections of DTMF method are supported.  
Send Flash Event  
Default is NO. If set to yes, flash will be sent as DTMF event.

conference. *23 will be disabled.  
Offhook  
Auto-Dial  
This parameter allows users to configure a User ID or extension number to be  
automatically dialed upon offhook. Please note that only the user part of a SIP  
address needs to be entered here. The HandyTone ATA will automatically  
append the “@” and the host portion of the corresponding SIP address.  
Proxy-Require  
SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.  
Default is No.  
Disable Call  
Waiting  
NAT Traversal  
(STUN)  
This parameter defines whether the HandyTone ATA NAT traversal  
mechanism will be activated or not. If activated (by choosing “Yes”) and a  
STUN server is also specified, then the HandyTone ATA will behave according  
to the STUN client specification. Under this mode, the embedded STUN client  
inside the HandyTone ATA will attempt to detect if and what type of  
firewall/NAT it is sitting behind through communication with the specified  
STUN server. If the detected NAT is a Full Cone, Restricted Cone, or a Port-  
Restricted Cone, the HandyTone ATA will attempt to use its mapped public IP  
address and port in all its SIP and SDP messages. If the NAT Traversal field is  
set to “Yes” with no specified STUN server, the HandyTone ATA will  
periodically (every 20 seconds or so) send a blank UDP packet (with no  
payload data) to the SIP server to keep the “hole” on the NAT open.  
No Key Entry  
Timeout  
Default is 4 seconds.

HandyTone-496 User Manual  
Grandstream Networks, Inc.  
Preferred Vocoder The HandyTone ATA supports up to 6 different Vocoder types including G.711  
A-/U-lawG.723.1, G.726, G.729A/B, iLBC. Depending on the product  
model, some of these Vocoders may not be provided in standard release.  
Users can configure Vocoders in a preference list that will be included with the  
same preference order in SDP message. The first Vocoder in this list can be  
entered by choosing the appropriate option in “Choice 1”. Similarly, the last  
Vocoder in this list can be entered by choosing the appropriate option in  
“Choice 6”.  
G723 Rate:  
This defines the encoding rate for G723 vocoder. By default, 6.3kbps rate is  
chosen.  
iLBC frame size:  
This sets the iLBC frame size in 20ms or 30ms  
iLBC payload type: This defines payload time for iLBC. Default value is 97. The valid range is  
between 96 and 127.  
Voice Frames per  
TX  
This field contains the number of voice frames to be transmitted in a single  
packet. When setting this value, the user should be aware of the requested  
packet time (used in SDP message) as a result of configuring this parameter.  
This parameter is associated with the first vocoder in the above vocoder  
Preference List or the actual used payload type negotiated between the 2  
conversation parties at run time.  
e.g., if the first vocoder is configured as G723 and the “Voice Frames per TX”  
is set to be 2, then the “ptime” value in the SDP message of an INVITE request  
will be 60ms because each G723 voice frame contains 30ms of audio.  
Similarly, if this field is set to be 2 and if the first vocoder chosen is G729 or  
G711 or G726, then the “ptime” value in the SDP message of an INVITE  
request will be 20ms.  
If the configured voice frames per TX exceeds the maximum allowed value, the  
HandyTone ATA will use and save the maximum allowed value for the  
corresponding first vocoder choice. The maximum value for PCM is 10(x10ms)  
frames; for G726, it is 20 (x10ms) frames; for G723, it is 32 (x30ms) frames;  
for G729/G728, 64 (x10ms) and 64 (x2.5ms) frames respectively.  
Silence Suppression This controls the silence suppression/VAD feature of G723. If set to “Yes”,  
when a silence is detected, small quantity of VAD packets (instead of audio  
packets) will be sent during the period of no talking. If set to “No”, this feature  
is disabled.  
Fax Mode  
T.38 (Auto Detect) FoIP by default, or Pass-Through (must use codec  
PCMU/PCMA)

HandyTone-496 User Manual  
Grandstream Networks, Inc.  
Early Dial  
This parameter controls whether the phone will attempt to send an early  
INVITE each time a key is pressed when a user dials a number. If set to “Yes”,  
an INVITE is sent using the dial-number collected thus far; Otherwise, no  
INVITE is sent until the “(Re-)Dial” button is pressed or after about 5 seconds  
have elapsed if the user forgets to press the “(Re-)Dial” button.  
The “Yes” option should be used ONLY if there is a SIP proxy configured and  
the proxy server supports 484 Incomplete Address response. Otherwise, the call  
will most likely be rejected by the proxy (with a 404 Not Found error).  
Please note that this feature is NOT designed to work with and should NOT be  
enabled for direct IP-to-IP calling.  
Dial Plan Prefix  
Sets the prefix added to each dialed number  
Use # as  
Send Key  
This parameter allows users to configure the “#” key to be used as the “Send”  
(or “Dial”) key. If set to “Yes”, pressing this key will immediately trigger the  
sending of dialed string collected so far. In this case, this key is essentially  
equivalent to the “(Re)Dial” key. If set to “No”, this “#” key will then be  
included as part of the dial string to be sent out.  
Subscribe for MWI: Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting  
Indication will be sent periodically.  
Send Anonymous  
If this parameter is set to “Yes”, the “From” header in outgoing INVITE  
message will be set to anonymous, essentially blocking the Caller ID from  
displaying.  
Lock keypad  
update  
If this parameter is set to “Yes”, the configuration update via keypad is  
disabled.  
Special Feature  
Default is Standard. Choose the selection to meet some special requirements  
from Soft Switch vendors like Lucent FS5000 Simple Endpoint, CBCOM, etc.  
Distinct Ring Tones Using these settings, user can configure ring or tone frequencies according to  
their preference. By default they are set to North American frequencies.  
Frequencies should be configured with known values to avoid uncomfortable  
high pitch sounds. ON is the period of ringing (“On time” in ‘ms’) while OFF  
is the period of silence. In order to set a continuous ring, OFF should be zero.  
Otherwise it will ring ON ms and a pause of OFF ms and then repeat the  
pattern.  
Ring 1 - 6 are reserved for distinct call waiting tones through SIP Alert-Info.  
Ring 7 – 12 are distinct ring tones through SIP Alert-Info. Both client and  
Server need to support this to be a useful feature. Currently, distinct ring tone  
feature is only supported under Lucent Special Feature.  
Volume  
Amplification  
Handset volume adjustment. RX is for receiving volume, TX is for  
transmission volume. Default values are 0dB for both parameters. +6dB  
generates the highest volume and -6dB generates the lowest volume.

6.3 Configuration through a Central Server  
Grandstream HandyTone ATAs can be automatically configured from a central provisioning system.  
When HandyTone ATA boot up, it will send TFTP or HTTP request to download configuration file,  
“cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the HandyTone ATA.  
The configuration files can be downloaded via TFTP or HTTP from the central server. A service  
provider or an enterprise with large deployment of HandyTone ATA can easily manage the  
configuration and service provisioning of individual devices remotely from a central server.  
Grandstream provides a licensed provisioning system called GAPS that can be used to support  
automated configuration of HandyTone ATA. GAPS (Grandstream Automated Provisioning System)  
uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication  
protocols to communicate with each individual HandyTone ATA for firmware upgrade, remote reboot,  
etc.  
Grandstream provide GAPS (Grandstream Automated Provisioning System) service to VoIP service  
providers. It could be either simple redirection or with certain special provisioning settings. Initially  
upon booting up, Grandstream devices by default point to Grandstream provisioning server GAPS,  
based on the unique MAC address of each device, GAPS provision the devices with redirection  
settings so that they will be redirected to customer’s TFTP or HTTP server for further provisioning.  
Grandstream also provide GAPSLite software package which contains our NAT friendly TFTP server  
and a configuration tool to facilitate the task of generating device configuration files.  
The GAPSLite configuration tool is now free to end users. The tool and configuration template are  
For details on how GAPS works, please contact Grandstream and refer to the documentation of GAPS  
product provided.

7 Software Upgrade  
Software upgrade can be done via either TFTP or HTTP. The corresponding configuration settings are  
in the ADVANCED SETTINGS configuration page.  
7.1  
Firmware Upgrade through TFTP/HTTP  
To upgrade via TFTP or HTTP, the “Firmware Upgrade and Provisioning upgrade via” field needs to  
be set to TFTP or HTTP, respectively. “Firmware Server Path” needs to be set to a valid URL of a  
TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples of  
some valid URL.  
e.g. firmware.mycompany.com:6688/Grandstream/1.0.3.44  
e.g. 168.75.215.190  
NOTES:  
TFTP server in IP address format can be configured via IVR. Please refer to section 6.1.3 for  
instructions. If TFTP server is in FQDN format, it must be set via web configuration interface.  
Once a “Firmware Server Path” is set, user needs to update the settings and reboot the device.  
If the configured firmware server is found and a new code image is available, the HandyTone  
ATA will attempt to retrieve the new image files by downloading them into the HandyTone  
ATA’s SRAM. During this stage, the HandyTone ATA’s LEDs will blink until the  
checking/downloading process is completed. Upon verification of checksum, the new code  
image will then be saved into the Flash. If TFTP/HTTP fails for any reason (e.g., TFTP/HTTP  
server is not responding, there are no code image files available for upgrade, or checksum test  
fails, etc), the HandyTone ATA will stop the TFTP/HTTP process and simply boot using the  
existing code image in the flash.  
Firmware upgrade may take as long as 1 to 20 minutes over Internet, or just 20+ seconds if it is  
performed on a LAN. It is recommended to conduct firmware upgrade in a controlled LAN  
environment if possible. For users who do not have a local firmware upgrade server,  
Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware  
upgrade. Please check the Services section of Grandstream’s Web site to obtain our public  
TFTP server’s IP address.  
Alternatively, user can download a free TFTP or HTTP server and conduct local firmware  
upgrade. A free windows version TFTP server is available for download from  
them under the root directory of the TFTP server. Put the PC running the TFTP server and the  
HandyTone ATA in the same LAN segment. Please go to File -> Configure -> Security to  
change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the  
firmware upgrade. Start the TFTP server, in the HandyTone ATA’s web configuration page,  
configure the Firmware Server Path with the IP address of the PC, update the change and  
reboot the unit. Please be advised that our client will pull out firmware from the WAN side, if  
the TFTP server is connected to the device’s LAN port, the firmware upgrade will not work by  
design.

HandyTone-496 User Manual  
7.2 Configuration File Download  
Grandstream Networks, Inc.  
Grandstream SIP Device can be configured via Web Interface as well as via Configuration File  
through TFTP or HTTP. “Config Server Path” is the TFTP or HTTP server path for configuration file.  
It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can  
be same or different from the “Firmware Server Path”.  
A configuration parameter is associated with each particular field in the web configuration page. A  
parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric  
numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a  
detailed parameter list, please refer to the corresponding firmware release configuration template.  
When Grandstream Device boots up or reboots, it will issue request for configuration file named  
“cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e.,  
“cfg000b820102ab”. The configuration file name should be in lower cases.  
7.3  
Firmware and Configuration File Prefix and Postfix  
Starting from firmware version 1.0.3.18 for HandyTone-496, adding prefix and postfix for both  
firmware and configuration file is supported.  
Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix  
and Postfix. This makes it the possible to store ALL of the firmware with different version in one  
single directory. Similarly, Config File Prefix and Postfix allows device to download the configuration  
file with the matching Prefix and Postfix. Thus multiple configuration files for the same device can be  
stored in one directory.  
In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”,  
the device will only issue firmware upgrade request if there are changes in the firmware Prefix or  
Postfix.  
7.4  
Managing Firmware and Configuration File Download  
When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in  
minutes, default and minimum is 60 minutes) to have the devices periodically check with either  
Firmware Server or Config Server, whenever they are defined. This allows the device periodically  
check if there are any new changes need to be taken on a scheduled time. By defining different  
intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File  
download in minutes to reduce the Firmware or Provisioning Server load at any given time.

An FXS device has hardware to generate the ring signal to the FXO extension (usually an  
analog phone).  
An FXS device will allow any FXO device to operate as if it were connected to the phone  
company. This makes your PBX the POTS+PSTN for the phone.  
The FXS Interface connects to FXO devices (by an FXO interface, of course).  
DHCP  
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating the  
configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP  
addresses, to deliver TCP/IP stack configuration parameters such as the subnet mask and  
default router, and to provide other configuration information such as the addresses for printer,  
time and news servers.  
ECHO CANCELLATION  
Echo Cancellation is used in telephony to describe the process of removing echo from a voice  
communication in order to improve voice quality on a telephone call. In addition to improving  
quality, this process improves bandwidth savings achieved through silence suppression by  
preventing echo from traveling across a network.  
There are two types of echo of relevance in telephony: acoustic echo and hybrid echo. Speech  
compression techniques and digital processing delay often contribute to echo generation in  
telephone networks.  
H.323  
HTTP

IP Telephony  
(Internet Protocol telephony, also known as Voice over IP Telephony) A general term for the  
technologies that use the Internet Protocol's packet-switched connections to exchange voice,  
fax, and other forms of information that have traditionally been carried over the dedicated  
circuit-switched connections of the public switched telephone network (PSTN). The basic steps  
involved in originating an IP Telephony call are conversion of the analog voice signal to digital

format and compression/translation of the signal into Internet protocol (IP) packets for  
transmission over the Internet or other packet-switched networks; the process is reversed at the  
receiving end. The terms IP Telephony and Internet Telephony are often used to mean the  
same; however, they are not 100 per cent interchangeable, since Internet is only a subcase of  
packet-switched networks. For users who have free or fixed-price Internet access, IP Telephony  
software essentially provides free telephone calls anywhere in the world. However, the  
challenge of IP Telephony is maintaining the quality of service expected by subscribers.  
Session border controllers resolve this issue by providing quality assurance comparable to  
legacy telephone systems.  
IVR  
IVR is a software application that accepts a combination of voice telephone input and touch-  
tone keypad selection and provides appropriate responses in the form of voice, fax, callback, e-  
mail and perhaps other media.  
MTU  
A Maximum Transmission Unit (MTU) is the largest size packet or frame, specified in octets  
(eight-bit bytes), that can be sent in a packet- or frame-based network such as the Internet. The  
maximum for Ethernet is 1500 byte.  
NAT  
NTP  
Network Address Translation  
Network Time Protocol, a protocol to exchange and synchronize time over networks  
The port used is UDP 123  
Grandstream products using NTP to get time from Internet  
OBP/SBC  
Outbound Proxy or another name Session Border Controller. A device used in VoIP networks.  
OBP/SBCs are put into the signaling and media path between calling and called party. The  
OBP/SBC acts as if it was the called VoIP phone and places a second call to the called party.  
The effect of this behaviour is that not only the signaling traffic, but also the media traffic  
(voice, video etc) crosses the OBP/SBC. Without an OBP/SBC, the media traffic travels  
directly between the VoIP phones. Private OBP/SBCs are used along with firewalls to enable  
VoIP calls to and from a protected enterprise network. Public VoIP service providers use  
OBP/SBCs to allow the use of VoIP protocols from private networks with internet connections  
using NAT.  
PPPoE  
PSTN  
Point-to-Point Protocol over Ethernet, is a network protocol for encapsulating PPP frames in  
Ethernet frames. It is used mainly with cable modem and DSL services.

RTCP  
RTP  
Real-time Transport Control Protocol, defined in RFC 3550, a sister protocol of the Real-time  
Transport Protocol (RTP), It partners RTP in the delivery and packaging of multimedia data,  
but does not transport any data itself. It is used periodically to transmit control packets to  
participants in a streaming multimedia session. The primary function of RTCP is to provide  
feedback on the quality of service being provided by RTP.  
Real-time Transport Protocol defines a standardized packet format for delivering audio and  
video over the Internet. It was developed by the Audio-Video Transport Working Group of the  
IETF and first published in 1996 as RFC 1889  
SDP  
SIP  
Session Description Protocol, is a format for describing streaming media initialization  
parameters. It has been published by the IETF as RFC 2327.  
Session Initiation Protocol, An IP telephony signaling protocol developed by the IETF  
(RFC3261). SIP is a text-based protocol suitable for integrated voice-data applications. SIP is  
designed for voice transmission and uses fewer resources and is considerably less complex than  
H.323.  
All Grandstream products are SIP based  
STUN  
TCP  
Simple Traversal of UDP over NATs, is a network protocol allowing clients behind NAT (or  
multiple NATs) to find out its public address, the type of NAT it is behind and the internet side  
port associated by the NAT with a particular local port. This information is used to set up UDP  
communication between two hosts that are both behind NAT routers. The protocol is defined in  
RFC 3489. STUN will usually work good with non-symmetric NAT routers.  
Transmission Control Protocol, is one of the core protocols of the Internet protocol suite. Using  
TCP, applications on networked hosts can create connections to one another, over which they  
can exchange data or packets. The protocol guarantees reliable and in-order delivery of sender  
to receiver data.  
TFTP  
UDP  
Trivial File Transfer Protocol, is a very simple file transfer protocol, with the functionality of a  
very basic form of FTP; It uses UDP (port 69) as its transport protocol.  
User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using  
UDP, programs on networked computers can send short messages known as datagrams to one  
42  
 
HandyTone-496 User Manual  
Grandstream Networks, Inc.  
another. UDP does not provide the reliability and ordering guarantees that TCP does;  
datagrams may arrive out of order or go missing without notice. However, as a result, UDP is  
faster and more efficient for many lightweight or time-sensitive purposes.  
VAD  
Voice Activity Detection or Voice Activity Detector is an algorithm used in speech processing  
wherein, the presence or absence of human speech is detected from the audio samples.  
VLAN  
VoIP  
A virtual LAN, known as a VLAN, is a logically-independent network. Several VLANs can co-  
exist on a single physical switch. It is usually refer to the IEEE 802.1Q tagging protocol.  
Voice over IP  
VoIP encompasses many protocols. All the protocols do some form of signalling of call  
capabilities and transport of voice data from one point to another. e.g: SIP, H.323, etc.
