Parameter Description
When ISDN Tunneling is enabled, the device sends all ISDN
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.
Note:
■ 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.
'Enable ISDN Tunneling IP
to Tel'
isdn-tnl-ip2tel
[EnableISDNTunnelingIP2
Tel]
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: The feature is similar to that of the AddIEinSetup
parameter. If both parameters are configured, the AddIEinSetup
parameter is ignored.
'Enable QSIG Tunneling'
qsig-tunneling
[EnableQSIGTunneling]
Global parameter that enables QSIG tunneling-over-SIP for all
calls. You can also configure this feature per specific calls,
using IP Profiles (IpProfile_EnableQSIGTunneling). For a
detailed description of the parameter and for configuring this
feature in the IP Profiles table, see Configuring IP Profiles.
Note: If this feature is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated
with the IP Profile.
