ini File Field Name
Web Parameter Name
Valid Range and Description
EnableVoiceDetection
1 = The gateway sends 200 OK message (in response to INVITE) when
speech/fax/modem is detected.
0 = The gateway sends 200 OK message (in response to INVITE) immediately
after the gateway finishes dialing (default).
Note 1: To activate this feature set the parameter ‘EnableDSPIPMDetectors’ to 1.
Usually this feature is used only when early media is used to establish voice path
before the call is answered.
Note 2: This feature is applicable only when the protocol type is CAS.
EnableDSPIPMDetectors
Enables / disables the IPmedia DSP detectors.
0 = Disable (default).
1 = Enable.
Note1: The gateway's Feature Key should contain the “IPMDetector” DSP option.
Note 2: When EnableDSPIPMDetectors = 1, the number of available gateway
channels is reduced by a factor of 5/6. For example, a gateway with 8 E1 spans,
capacity is reduced to 6 spans (180 channels), while a gateway with 8 T1 spans,
capacity remains the same (192 channels).
XChannelHeader
0 = x-channel header is not used (default).
1 = x-channel header is generated, with trunk/B-channel information.
The header provides information on the E1/T1 physical trunk/B-channel on which
the call is received or placed. For example ‘x-channel: DS/DS1-5/22’. This header
is generated by the gateway and is sent in the following messages: INVITE and
183/180/200OK responses.
AddIEinSetup
[Add IE in SETUP]
This parameter enables to add an optional Information Element data (in hex
format) to ISDN SETUP message.
For example: to add the following IE: ‘0x20,0x02,0x00,0xe1’, define: ‘AddIEinSetup
= 200200e1’.
Note: This IE is sent from the Trunk Group IDs defined by the parameter
‘SendIEonTG’.
SendIEonTG
[Trunk Groups to Send IE]
A list of Trunk Group IDs (up to 50 characters) from where the optional ISDN IE,
defined by the parameter ‘AddIEinSetup’, is sent.
For example: ‘SendIEonTG = 1,2,4,10,12,6’.
ISDNDMSTimerT310
Overrides the T310 timer for the DMS-100 ISDN variant.
T310 defines the timeout between the reception of Proceeding message and the
reception of Alert / Connect message.
The valid range is 10 to 30. The default value is 10 (seconds).
Note: Applicable only to Nortel DMS and Nortel MERIDIAN PRI variants
(ProtocolType = 14 and 35).
ISDNJapanNTTTimerT3J
A
T3_JA timer (in seconds).
This parameter overrides the internal PSTN T301 timeout on the Users Side (TE
side).
If an outgoing call from the gateway to ISDN is not answered during this timeout,
the call is released.
The valid range is 10 to 240. The default value is 50.
Applicable only to Japan NTT PRI variant (ProtocolType = 16).
Note: This timer is also affected by the parameter ‘PSTNAlertTimeout’.
EarlyAnswerTimeout
Defines the time (in seconds) the gateway waits for a CONNECT response from
the called party (Tel side) after sending a SETUP message. If the timer expires,
the call is answered by sending a 200 OK message (IP side).
The valid range is 0 to 600. The default value is 0 (disable).
