Description
■ The feature is similar to that of the
EnableISDNTunnelingIP2Tel parameter. If both
parameters are configured, the
EnableISDNTunnelingIP2Tel parameter takes
precedence.
■ The corresponding global parameter is AddIEinSetup.
Enables QSIG tunneling-over-SIP for this SIP entity. This
is according to IETF Internet-Draft draft-elwell-sipping-
qsig-tunnel-03 and ECMA-355 and ETSI TS 102 345.
■ [0] Disable (default).
■ [1] Enable = Enables 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.
Note:
■ The parameter is applicable only to digital interfaces.
■ 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
Tunneling.
■ The corresponding global parameter is
EnableQSIGTunneling.
Enables the device to copy the called number, received in
the SIP INVITE message, to the redirect number in the
outgoing Q.931 Setup message, for IP-to-Tel calls. Thus,
even if there is no SIP Diversion or History header in the
incoming INVITE message, the outgoing Q.931 Setup
message will contain a redirect number.
■ [0] Disable (default).
■ [1] After Manipulation = Copies the called number
after manipulation. The device first performs IP-to-Tel
destination phone number manipulation, and only then
copies the manipulated called number to the redirect
number sent in the Q.931 Setup message to the Tel.
Thus, the called and redirect numbers are the same.
