3Com VCX V7122 SIP VoIP Gateway User Manual
Valid Range and Description
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.
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.
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 protocols.
This parameter enables the VCX 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.
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 and dialing the Refer-to number to the
Switch and then releasing the call.
Note: A specific NFA CAS table is required.
0
= Disabled (default).
1 = TDM Tunneling is enabled.
When TDM Tunneling is enabled, the originating VCX V7122 automatically
initiates SIP calls from all enabled B-channels belonging to the E1/T1/J1 spans
that are configured with the 'Transparent' protocol. The called number of each
call is the internal phone number of the B-channel that the call originates from.
The IP to Trunk Group routing table is used to define the destination IP
address of the terminating VCX V7122. The terminating VCX V7122 gateway
automatically answers these calls if its E1/T1 protocol is set to 'Transparent'
(ProtocolType = 5).
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.
