xfer-complete-timeout
[ISDNTransferComplete
Timeout]
Defines the timeout (in seconds) for determining ISDN call transfer
(ECT, RLT, or TBCT) failure. If the device does not receive any
response to an ISDN transfer attempt within this user-defined time, the
device identifies this as an ISDN transfer failure and subsequently
performs a hairpin TDM connection or sends a SIP NOTIFY message
with a SIP 603 response (depending whether hairpin is enabled or
disabled, using the parameter DisableFallbackTransferToTDM).
The valid range is 1 to 10. The default is 4.

Transfer

network-isdn-xfer
[EnableNetworkISDNTra
nsfer]
Determines whether the device allows interworking of network-side
received ECT/TBCT Facility messages (NI-2 TBCT - Two B-channel
Transfer and ETSI ECT - Explicit Call Transfer) to SIP REFER.

[0] Disable = Rejects ISDN transfer requests.

[1] Enable = (Default) The device sends a SIP REFER message to
the remote call party if ECT/TBCT Facility messages are received
from the ISDN side (e.g., from a PBX).
[DisableFallbackTransfer
ToTDM] Enables "hairpin" TDM transfer upon ISDN (ECT, RLT, or TBCT) call
transfer failure. When this feature is enabled and an ISDN call transfer
failure occurs, the device sends a SIP NOTIFY message with a SIP 603
Decline response.

[0] = (Default) The device performs a hairpin TDM transfer upon
ISDN call transfer.

[1] = Hairpin TDM transfer is disabled.
Enable QSIG Transfer
Update
qsig-xfer-update
[EnableQSIGTransferUp
date]
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.
is-cas-sndhook-flsh
[CASSendHookFlash]
Enables sending Wink signal toward CAS trunks.

[0] = Disable (default)
