Valid Range and Description
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.
It is necessary to set the parameter ISDNDuplicateQ931BuffMode
to 128 (duplicate all messages) for this mechanism to function.
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.
Controls the activation / deactivation of delivering raw Q.931 messages.
0 = ISDN messages aren't duplicated (default).
128 = All ISDN messages are duplicated.
This parameter is not updated on-the-fly and requires a gateway
reset.
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.
It is necessary to set the parameter
'ISDNDuplicateQ931BuffMode' to 128 (duplicate all messages) so
that this mechanism can function.
