SIP User's Manual
Enables QSIG tunneling-over-SIP for all calls. This is according
to IETF Internet-Draft draft-elwell-sipping-qsig-tunnel-03 and
ECMA-355 and ETSI TS 102 345.

[0] Disable = Disable (default).

[1] Enable = Enable QSIG tunneling from QSIG to SIP and
vice versa. All QSIG messages are sent as raw data in
corresponding SIP messages using a dedicated message
body.
Notes:

You can enable QSIG tunneling per specific calls by
enabling QSIG tunneling for an IP Profile.

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 to all ISDN
variants (in addition to the QSIG protocol).

For more information on QSIG tunneling, see 'QSIG
Tunneling' on page 260.
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.

[0] Disable (default)

[1] Enable
Notes:

This parameter is applicable to Euro ISDN variants - from
TE (user) to NT (network).

If the parameter is disabled, the device plays a Held tone to
the Tel side when a SIP request with 0.0.0.0 or "inactive" in
SDP is received. An appropriate CPT file with the Held tone
should be used.
Determines the activation/deactivation of delivering raw Q.931
messages.

[0] = ISDN messages aren't duplicated (default).

[128] = All ISDN messages are duplicated.
Note: For this parameter to take effect, a device reset is
required.
Determines the encoding format of the SIP Tel URI parameter
'isub', which carries the encoding type of ISDN subaddresses.
This is used to identify different remote ISDN entities under the
700
