ini File Field Name
Web Parameter Name
Valid Range and Description
EnableAOC
0 = Not used (default).
1 = ISDN Advice of Charge (AOC) messages are interworked to SIP.
The gateway supports reception of ISDN (Euro ISDN) AOC messages. AOC
messages can be received during a call (Facility messages) or at the end of a call
(Disconnect or Release messages). The gateway converts the AOC messages
into SIP INFO (during a call) and BYE (end of a call) messages using a
proprietary AOC SIP header. The gateway supports both Currency and Pulse
AOC messages.
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 AudioCodes 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.
Note: 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.
CASAddressingDelimiter
s
Determines if delimiters are added to the dialed address or dialed ANI
parameters.
Valid options include:
0 = Disable (default)
1 = Enable
When this parameter is enabled, delimiters such as '*', '#', and 'ST' are added to
the dialed address or dialed ANI parameters. When it is disabled, the address and
ANI strings remain without delimiters.
