Web Parameter Name
Valid Range and Description
EnableTDMoverIP
[Enable TDM Tunneling]
0 = Disabled (default).
1 = TDM Tunneling is enabled.
When TDM Tunneling is enabled, the originating gateway automatically initiates
SIP calls from all enabled B-channels belonging to the E1/T1/J1 spans that are
configured with the ‘Transparent’ protocol. The called number of each call is the
internal phone number of the B-channel that the call originates from. The IP to
Trunk Group routing table is used to define the destination IP address of the
terminating gateway. The terminating gateway automatically answers these calls
if its E1/T1 protocol is set to ‘Transparent’ (ProtocolType = 5).
EnableISDNTunnelingTel
2IP
[Enable ISDN Tunneling
Tel2IP]
Valid options include:
0 = Disable (default).
1 = Enable ISDN Tunneling from ISDN PRI to SIP using a proprietary SIP header
2 = Enable ISDN Tunneling from ISDN PRI to SIP using a dedicated message
body
When ISDN Tunneling is enabled, the gateway sends all ISDN PRI messages
using the correlated SIP messages. Setup is tunneled using INVITE, all mid-call
messages are tunneled using INFO, and Disconnect/Release is tunneled using
BYE. 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: It is necessary to set the parameter ISDNDuplicateQ931BuffMode to 128
(duplicate all messages) for this mechanism to function.
EnableISDNTunnelingIP2
Tel
[Enable ISDN Tunneling
IP2Tel]
Valid options include:
0 = Disable (default)
1 = Enable ISDN Tunneling from SIP to ISDN PRI using a proprietary SIP header
2 = Enable ISDN Tunneling from SIP to ISDN PRI using a dedicated message
body
When ISDN Tunneling is enabled, the gateway extracts the raw data received in a
proprietary SIP header (X-ISDNTunnelingInfo) or a dedicated message body
(application/isdn) in the SIP messages and sends the data as ISDN messages to
the PSTN side.
ISDNDuplicateQ931BuffM
ode
Controls the activation / deactivation of delivering raw Q.931 messages.
0 = ISDN messages aren’t duplicated (default).
128 = All ISDN messages are duplicated.
Note: This parameter is not updated on-the-fly and requires a gateway reset.
EnableQSIGTunneling
[Enable QSIG Tunneling]
Enables QSIG tunneling over SIP according to <draft-elwell-sipping-qsig-tunnel-
03>.
0 = Disable (default).
1 = Enable QSIG tunneling from QSIG to SIP and vice versa.
When QSIG tunneling is enabled, all QSIG messages are sent as raw data in
corresponding SIP messages using a dedicated message body. Note that QSIG
tunneling must be enabled on both the originating and terminating gateways.
Note: It is necessary to set the parameter ‘ISDNDuplicateQ931BuffMode’ to 128
(duplicate all messages) so that this mechanism can function.
