Mediant 1000B Gateway & E-SBC
Parameter Description
Note: The parameter is applicable to ISDN Overlap mode only when
dialed numbers are sent using Q.931 Information messages.
[ConnectedNumberType] Defines the Numbering Type 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).

[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
[EnableISDNTunnelingTel2IP
]
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
[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.
