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 for IP-to-Tel calls.

[0] Disable (default)

[1] Enable ISDN Tunneling from IP to ISDN
When ISDN Tunneling is enabled, the device extracts raw data
received in the proprietary SIP header, x-isdntunnelinginfo, or a
dedicated message body (application/isdn) in the SIP message and
then sends the data in an ISDN message to the PSTN.
If the raw data in this SIP header is suffixed with the string "ADDE",
then the raw data is extracted and added as Informational Elements
(IE) in the outgoing Q.931 message. The tunneling of the x-
isdntunnelinginfo SIP header with IEs is converted from INVITE,
180, and 200 OK SIP messages to Q.931 SETUP, ALERT, and
CONNECT respectively.
For example, if the following SIP header is received,
x-isdntunnelinginfo: ADDE1C269FAA 06
800100820100A10F020136 0201F0A00702010102021F69
then it is added as an IE to the outgoing Q.931 message as
1C269FAA 06 800100820100A10F020136
0201F0A00702010102021F69, where, for example, "1C269F" is a
26 byte length Facility IE.
Note: This feature is similar to that of the AddIEinSetup parameter.
If both parameters are configured, the x-isdntunneling parameter
takes precedence.
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 (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:

This feature can also be configured in 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., duplicate all messages).

To define the format of encapsulated QSIG messages, use the
QSIGTunnelingMode parameter.

Tunneling according to ECMA-355 is applicable to all ISDN
variants (in addition to the QSIG protocol).
