SIP User's Manual
When ISDN Tunneling is enabled, the device extracts raw
data received in a proprietary SIP header (X-
ISDNTunnelingInfo) or a dedicated message body
(application/isdn) in the SIP messages and sends the data as
ISDN messages to the PSTN side.
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
messages).
Controls the activation / deactivation of delivering raw Q.931
messages.
[0] = ISDN messages aren't duplicated (default).
[128] = All ISDN messages are duplicated.
Note: This parameter is not updated on-the-fly and requires a
device reset.
Enables the device to play a busy or reorder tone to the PSTN
after a Tel-to-IP call is released.
[0] Don't Play = Immediately sends an ISDN Disconnect
message (default).
[1] Play when Disconnecting = Sends an ISDN Disconnect
message with PI = 8 and plays a busy or reorder tone to
the PSTN (depending on the release cause).
[2] Play before Disconnect = Delays the sending of an
ISDN Disconnect message for a user-defined time
(configured by the TimeForReorderTone parameter) and
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.
Enables the playing of a ringback tone (RBT) to the trunk side
and per trunk (where ID depicts the trunk number and 0 is the
first trunk). This parameter also determines the method for
playing the RBT.
[-1] = Not configured - use the value of the parameter
PlayRBTone2Tel (default).
[0] Don't Play = The device configured with ISDN/CAS
protocol type does not play an RBT. No PI is sent to the
ISDN unless the parameter ProgressIndicator2ISDN_ID is
