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.

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 (DMS-100), TBCT (NI2), and ECT
(EURO ISDN).
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.
 [4] = Supports QSIG Single Step transfer.
IP-to-Tel: When a SIP REFER message is received, the gateway performs
a transfer by sending a FACILITY message to the PBX, initiating Single
Step transfer. Once a success return result is received, the transfer is
completed.
Tel-to-IP: When a FACILITY message initiating Single Step transfer is
received from the PBX, a REFER message is sent to the IP side.
To configure Trunk Transfer Mode using the Embedded Web Server, refer to
'Trunk Settings' on page 178.
CASTransportType
For a description of this parameter, refer to 'Configuring the Voice Settings' on
page 166.
CASAddressingDeli

parameters.
 [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.
