SIP User's Manual
Notes:
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.
Enables ISDN Tunneling to the Tel side.
[0] Disable (default)
[1] Enable ISDN Tunneling from IP to ISDN
When ISDN Tunneling is enabled, the device extracts 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.
Enables QSIG tunneling-over-SIP according to the IETF
Internet-Draft draft-elwell-sipping-qsig-tunnel-03 and ECMA-
355 and ETSI TS 102 345 standards.
[0] Disable = Disable (default).
[1] Enable = 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.
Notes:
QSIG tunneling must be enabled on originating and
terminating devices.
To enable this function, set the
ISDNDuplicateQ931BuffMode parameter to 128 (i.e.,
duplicate all messages).
To define the format of encapsulated QSIG messages, use
the QSIGTunnelingMode parameter.
Tunneling according to ECMA-355 is applicable also to all
ISDN variants (in addition to the QSIG protocol).
For a detailed description on QSIG tunneling, see ''QSIG
Tunneling'' on page 650.
Defines the format of encapsulated QSIG message data in the
SIP message MIME body.
[0] = ASCII presentation of Q.931 QSIG message (default).
[1] = Binary encoding of Q.931 QSIG message (according
to ECMA-355, RFC 3204, and RFC 2025).
Note: This parameter is applicable only if the QSIG Tunneling
feature is enabled (using the EnableQSIGTunneling
parameter).
Enables SIP-to-ISDN interworking of the Hold/Retrieve
supplementary service.
