Version 6.8 839 Mediant 500 E-SBC
Parameter Description
[EnableISDNTunnelingTel2IP
]

[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.
Web/EMS: Enable ISDN
Tunneling IP to Tel
CLI: isdn-tnl-ip2tel
[EnableISDNTunnelingIP2Tel
]
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.
Web/EMS: Enable QSIG
Tunneling
CLI: qsig-tunneling
[EnableQSIGTunneling]
Global parameter that enables QSIG tunneling-over-SIP for all calls.
You can also configure this functionality per specific calls, using IP
Profiles (IpProfile_EnableQSIGTunneling). For a detailed
description of this parameter and for configuring this functionality in
the IP Profile table, see ''Configuring IP Profiles'' on page
304 .
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with
the IP Profile.
[QSIGTunnelingMode] Defines the format of encapsulated QSIG message data in the SIP
message MIME body.

[0] = (Default) ASCII presentation of Q.931 QSIG message.

[1] = Binary encoding of Q.931 QSIG message (according to
