calls). This is interworked from the P-Asserted-Identity header in SIP

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 (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 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.
