Enables QSIG tunneling-over-SIP according to <draft-elwell-
sipping-qsig-tunnel-03>.

[0] Disable = Disable (default).

[1] Enable = Enable QSIG tunneling from QSIG to SIP and
vice versa.
When QSIG tunneling is enabled, all QSIG messages are sent
as raw data in corresponding SIP messages using a dedicated
message body.
Notes:

QSIG tunneling must be enabled on both originating and
terminating devices.

To enable this function, set the parameter
ISDNDuplicateQ931BuffMode to 128 (i.e., duplicate all

plays a busy or reorder tone to the PSTN. Applicable only if
the call is released from the IP [Busy Here (486) or Not
Found (404)] before it reaches the Connect state;
otherwise, the Disconnect message is sent immediately
and no tones are played.

playing the RBT.

[-1] = Not configured - use the value of the parameter
PlayRBTone2Tel (default).

