The VoiceGATE GATEWAY provides voice/fax service over IP network with
H.323 v3 protocol. By connecting to your existing ADSL or cable modem
service, which allows the use of a single, network for voice and fax services
with consequent saving in network infrastructure and greatly reduced
telephone charges. Ideal solution for providing low cost communications
between headquarters and branch offices in the world, as well as for SOHO
and office telephony applications.
VoiceGATE GATEWAY provides analog lines to connect local PSTN/PTT
interface (FXO), and converts voice/fax signal onto IP network. The
management feature is via RS-232C COM port and TELNET.

Peer-to-Peer Mode allows users to call other VoIP devices without using a
gatekeeper. When in Peer-To-Peer mode, VoiceGATE GATEWAY will send SETUP
message directly to the destination IP address once the dial is finished. Users
have 2 methods of dial. One is IP dialing, and the other is Phonebook dial, which
we will describe later. When using IP address as destination phone number, press
“*” as “.” in IP address expression, and press “#” when dial is finished. When using
Phonebook, users can dial predefined phone number, and press “#” (optional, to
accelerate the dial) as end of dial.
To configure Peer-To-Peer Mode in VoiceGATE GATEWAY, follow the steps
below:
1. Set Peer-To-Peer Mode, using “h323” command

The function is for user whose network environment is behind IP Sharing device. It is said
VoiceGATE GATEWAY is connected to the IP Sharing device.
An example such as ADSL network is in the following.
ATU-R ADSL Modem
WAN
IP Sharing device
LAN LAN
VoiceGATE GATEWAY PC


The WAN IP Address obtained from ADSL has two kinds of methods.
One is fixed IP Address, while user applies for one or more fixed IP Addresses.
Another is dynamic IP Address while user applies for dial-up connection way. 

The LAN IP Address of User’s PC can be set as DHCP client in order to gain an valid
one.

Anther IP Address for VoiceGATE GATEWAY must be set as an fixed one in order for
that IP Sharing device pass forwarding the relevant information from WAN to LAN.
Besides, a valid IP Address which meets the IP Sharing device (LAN site) is the
element.

VoiceGATE GATEWAY must enable the IP Sharing function for the fixed / dynamic
WAN IP Address.

IP Sharing device must have a function to do IP/Port mapping. Some is named as DMZ,
some is named as virtual server. The VoIP messages from WAN have to completely
pass forward to the LAN. It is said if the VoiceGATE GATEWAY is assigned a virtual
fixed IP Address such as 192.168.1.5, IP Sharing device must forward the VoIP
messages to 192.168.1.5.

This application note is going to describe the procedures of configuring the
disconnect tone on VoiceGATE GATEWAY in order to release LINE ports of
VoiceGATE GATEWAY after PSTN/PBX caller party is hung up.
:KDWLV'LVFRQQHFW7RQH
A caller make a telephone call to Gateway from PSTN side, VoiceGATE
GATEWAY will answer the call automatically. If the IP side of other VoIP devices
do not answer the call and the caller hang up the call, the PSTN/PBX will give
Gateway a disconnect tone automatically. Or, both devices are installed with
VoiceGATE GATEWAY and connect to local PSTN. If both parties are in talk mode,
one side hang up the call the VoiceGATE GATEWAY has to recognize the
disconnect tone from local PSTN. The VoiceGATE GATEWAY gateway will
recognize this disconnect tone and release the LINE port with the pre-defined busy
tone or reorder tone from VoiceGATE GATEWAY tone table.
If the other VoIP device of IP side hangs up the phone, the gateway will release
the LINE port automatically without analyzing disconnect tone from PSTN/PBX.
There are three parameters received from PSTN/PBX.
- High level frequency and Low level frequency
- Tone Cadence (ON/OFF intervals)
- Tone level
These parameters have to be properly configured to VoiceGATE GATEWAY in
order to recognize disconnect tone correctly. Each different PSTN/PBX have
different parameters. So, VoiceGATE GATEWAY has to configure tone table when
LINE port connect to different PSTN/PBX.

VoiceGATE GATEWAY has a default setting of disconnect tone (Busy tone 1,
Busy tone 2, reorder tone 1 and reorder tone 2 ). If the disconnect tone was
recognized correctly, the LINE port from PSTN/PBX will be released in two
seconds. Otherwise it may be released after one minute or lock this LINE
permanently.
The tone table parameters are shown as follows.
LowFreq 480: Low frequency is 480 HZ
HighFreq 620: High frequency is 620 HZ
LowFreqLevel 8: Low frequency level received range from PSTN/PBX
HighFreqLevel 8: High frequency level received range from PSTN/PBX
TOn1 - 50: Disconnect tone cadence ON time is 0.5 seconds
TOff1 - 50: Disconnect tone cadence OFF time is 0.5 seconds
( If this is continuous tone, the Toff has to set to 1023 )
TOn2 - 1023: Disconnect tone second cycle cadence ON time is OFF
TOff2 - 1023: Disconnect tone second cycle cadence OFF time is OFF
( If the tone cadence has only one cycle, the second cycle must set to 1023 )

a. The first one is using command “greetrd” from VoiceGATE GATEWAY. Once
you follow the instruction to analyze the disconnect tone, Gateway will
configure the tone table (Busy tone 1, Busy tone 2, reorder tone 1 and reorder
tone 2 ) with proper frequency and default tone level and cadence (Ton1/Toff1)
automatically. Or you may read the analysis tone frequency from command line
and configure to one of tone table manually.
The default tone level is set to 8. And the tone cadence (Ton1/Toff1) is set to
four different values on tone table. They are 0.1 second, 0.25 seconds, 0.5
seconds and 0.75 seconds with parameters 10/10, 25/25, 50/50 and 75/75.
If the PBX/PSTN cadence is not the value as default shown as above, you
need to use the following instruction to analyze ON/OFF intervals.
b. You may use your PC (START ÆProgram Files ÆAccessories ÆMultimedia
ÆRecorder) with Headset or Microphone to record the disconnect tone via a
telephone set from PSTN/PBX and save to a voice file. Then you can use
“CoolEdit Pro” software to analyze the frequency and ON/OFF time. Please visit
http://www.cooledit.com to download demo version for analysis. You can use this
program to analyze ON/OFF time and fill in to tone table.
