Mediant 500L Gateway & E-SBC
Parameter Description
The default is [0] (i.e., unknown).
configure voip > gateway
dtmf-supp-service supp-
service-settings >
connected-number-type
[ConnectedNumberPlan]
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).
Enable ISDN Tunneling Tel
to IP
isdn-tnl-tel2ip
[EnableISDNTunnelingTel2I
P]
Enables ISDN Tunneling.
[0] Disable (default).
[1] Using Header = Enable ISDN Tunneling from ISDN to SIP using
a proprietary SIP header.
[2] Using Body = Enable ISDN Tunneling from ISDN to SIP using a
dedicated message body.
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
[EnableISDNTunnelingIP2T
el]
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 functionality per specific calls, using IP
Profiles (IpProfile_EnableQSIGTunneling). For a detailed description of
the parameter and for configuring this functionality in the IP Profiles
