SIP User's Manual
the ISDN (for Tel-to-IP calls). This is interworked from the P-
Asserted-Identity header in SIP 200 OK.
The default is [0] (i.e., unknown).
Defines the Numbering Plan of the ISDN Q.931 Connected
Number IE that the device sends in the Connect message to
the ISDN (for Tel-to-IP calls). This is interworked from the P-
Asserted-Identity header in SIP 200 OK.
The default is [0] (i.e., unknown).
Enables ISDN Tunneling.

[0] Disable = Disable (default).

[1] Using Header = Enable ISDN Tunneling from ISDN PRI
to SIP using a proprietary SIP header.

[2] Using Body = Enable ISDN Tunneling from ISDN PRI to
SIP using a dedicated message body.
When ISDN Tunneling is enabled, the device sends all ISDN
PRI messages using the correlated SIP messages. The ISDN
Setup message is tunneled using SIP INVITE, all mid-call
messages are tunneled using SIP INFO, and ISDN
Disconnect/Release message is tunneled using SIP BYE
messages. The raw data from the ISDN is inserted into a
proprietary SIP header (X-ISDNTunnelingInfo) or a dedicated
message body (application/isdn) in the SIP messages.
Notes:

For this feature to function, you must set the parameter
ISDNDuplicateQ931BuffMode to 128 (i.e., duplicate all
messages).

ISDN tunneling is applicable for all ISDN variants as well as
QSIG.
Enables ISDN Tunneling to the Tel side.

[0] Disable (default)

[1] Enable ISDN Tunneling from IP to ISDN
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 for all calls. This is according
to IETF Internet-Draft draft-elwell-sipping-qsig-tunnel-03 and
ECMA-355 and ETSI TS 102 345.

[0] Disable = Disable (default).

[1] Enable = Enable QSIG tunneling from QSIG to SIP and
vice versa. All QSIG messages are sent as raw data in
corresponding SIP messages using a dedicated message
body.
Notes:

You can enable QSIG tunneling per specific calls by
enabling QSIG tunneling for an IP Profile.

QSIG tunneling must be enabled on originating and
terminating devices.

To enable this function, set the
ISDNDuplicateQ931BuffMode parameter to 128 (i.e.,
