Alert Timeout in seconds (ISDN T301 timer) for outgoing calls to PSTN.
The default is 180 seconds. The range is 0 to 240.
Note: The PSTN stack T301 timer can be overridden by a lower value, but it can't be
increased.
Defines the IP ISDN Transfer Capability of the Bearer Capability IE in ISDN Setup
messages.
0 = Audio 3.1 (default).
1 = Speech.
2 = Data.
Note: If this parameter isn't configured or equals to '–1', Audio 3.1 capability is used.
The parameter can overwrite the calling number screening indication for ISDN Tel IP
calls.
-1 = not configured (interworking from ISDN to IP) or set to 0 for CAS.
0 = user provided, not screened.
1 = user provided, verified and passed.
2 = user provided, verified and failed.
3 = network provided.
Note: Applicable only if Remote Party ID (RPID) header is enabled.
0 = Not Supported (default).
1 = Supports partial retrieval of Redirect Number (number only) from a Facility IE in
ISDN Setup messages. Applicable to Redirect number according to ECMA-173 Call
Diversion Supplementary Services.
Note: To enable this feature, 'ISDNDuplicateQ931BuffMode' must be set to 1.
0 = Do not relay the Carrier Identification Code (CIC) to ISDN (default).
1 = CIC is relayed to ISDN in Transit Network Selection IE.
If enabled, the CIC code (received in an Invite Request-URI) is included in a TNS IE in
ISDN Setup message. For example: INVITE sip:555666;cic=2345@100.2.3.4 sip/2.0.
Note: Currently this feature is supported only in SIP ISDN direction.
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 & ISDN protocols.
This parameter enables the Mediant 2000 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.
