Mediant 1000B Gateway & E-SBC
Parameter Description
 [1] = Hairpin TDM transfer is disabled.
Enable QSIG Transfer
Update
qsig-xfer-update
[EnableQSIGTransferUpdate]
Determines whether the device interworks QSIG Facility messages
with CallTranferComplete or CallTransferUpdate invoke application
protocol data units (APDU) to SIP UPDATE messages with P-
Asserted-Identity and optional Privacy headers. This feature is
supported for IP-to-Tel and Tel-to-IP calls.
 [0] Disable = (Default) Ignores QSIG Facility messages with
CallTranferComplete or CallTransferUpdate invokes.
 [1] Enable
For example, assume A and C are PBX call parties and B is the SIP
IP phone:
1 A calls B; B answers the call.
2 A places B on hold and calls C; C answers the call.
3 A performs a call transfer (the transfer is done internally by the
PBX); B and C are connected to one another.
In the above example, the PBX updates B that it is now talking with
C. The PBX updates this by sending a QSIG Facility message with
CallTranferComplete invoke APDU. The device interworks this
message to a SIP UPDATE message containing a P-Asserted-
Identity header with the number and name derived from the QSIG
CallTranferComplete RedirectionNumber and RedirectionName.
Note:
 For IP-to-Tel calls, the RedirectionNumber and RedirectionName
in the CallTRansferComplete invoke is derived from the P-
Asserted-Identity and Privacy headers in the received SIP INFO
message.
 To include the P-Asserted-Identity header in outgoing SIP
UPDATE messages, set the AssertedIDMode parameter to Add
is-cas-sndhook-flsh
[CASSendHookFlash]
Enables sending Wink signal toward CAS trunks.
 [0] = Disable (default)
 [1] = Enable
If the device receives a mid-call SIP INFO message with flashhook
event body (as shown below) and the parameter is set to 1, the
device generates a wink signal toward the CAS trunk. The CAS wink
signal is done by changing the A bit from 1 to 0, and then back to 1
for 450 msec.
