Parameter Description
Enable QSIG Transfer
Update
qsig-xfer-update
[EnableQSIGTransferUpdat
e]
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 P-Asserted-
Identity.
