Web Parameter Name
Valid Range and Description
TimeForReorderTone Busy or Reorder Tone duration the CAS gateway plays before releasing the
line.
The valid range is 0 to 15. The default value is 10 seconds.
Applicable also to ISDN if ‘PlayBusyTone2ISDN = 2’. Selection of Busy or
Reorder tone is done according to release cause received from IP.
DisconnectOnBusyTone
[Disconnect Call on
Detection of Busy Tone]
0 = Do not disconnect call on detection of busy tone
1 = Disconnect call on detection of busy tone (default).
This parameter is applicable to CAS & ISDN protocols.
PlayBusyTone2ISDN
[Play Busy Tone to Tel]
This parameter enables the V7122 ISDN gateway to play a Busy or a Reorder
tone to the PSTN after a call is released.
0 = Immediately sends an ISDN Disconnect message (default).
1 = Sends an ISDN Disconnect message with PI=8 and plays a Busy or a
Reorder tone to the PSTN (depending on the release cause).
2 = Delays the sending of an ISDN Disconnect message for
‘TimeForReorderTone’ seconds and plays a Busy or a Reorder tone to the
PSTN. Applicable only if the call is released from the IP before it reaches the
Connect state. Otherwise, the Disconnect message is sent immediately and no
tones are played.
TrunkTransferMode_X 0 = Not supported (default).
1 = Supports CAS NFA DMS-100 transfer.
When a SIP REFER message is received, the gateway performs a Blind
Transfer by executing a CAS Wink, waits for an acknowledge Wink from the
remote side, dials the Refer-to number to the switch and then releases the call.
A specific NFA CAS table is required.
2 = Supports ISDN transfer (RLT / TBCT / ECT).
When a SIP REFER message is received, the gateway performs
a transfer by sending FACILITY messages to the PBX with the
necessary information on the call’s legs that are to be connected.
The different ISDN variants use slightly different methods (using
FACILITY messages) to perform the transfer.
3 = Supports CAS Normal transfer.
When a SIP REFER message is received, the gateway performs
a Blind Transfer by executing a CAS Wink, dialing the Refer-to
number to the switch and then releasing the call.
CASTransportType
[CAS Transport Type]
0 = Disable CAS relay (default).
1 = Enable CAS relay mode using RFC 2833.
The CAS relay mode can be used with the TDM tunneling feature to enable
tunneling over IP for both voice and CAS signaling bearers.
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).
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.
This feature is applicable only when the protocol type is CAS.
