Parameter Description
TxDTMFOption
Web: Rx DTMF Option
CLI: rx-dtmf-option
[IpProfile_RxDTMFOption] Enables the device to declare the RFC 2833 'telephony-
event' parameter in the SDP.

[0] Not Supported

[3] Supported (default)
The device is always receptive to RFC 2833 DTMF relay
packets. Thus, it is always correct to include the 'telephony-
event' parameter by default in the SDP. However, some
devices use the absence of the 'telephony-event' in the SDP
to decide to send DTMF digits in-band using G.711 coder. If
this is the case, set this parameter to 0.
Note: The corresponding global parameter is
RxDTMFOption.
Web: Hold
CLI: enable-hold
[IpProfile_EnableHold] Enables the interworking of the Hold/Retrieve supplementary
service from ISDN PRI to SIP (digital interfaces).

[0] Disable

[1] Enable (default)
Notes:

Digital interfaces: To interwork the Hold/Retrieve
supplementary service from SIP to ISDN (QSIG and Euro
ISDN), set the EnableHold2ISDN parameter to 1.

The corresponding global parameter is EnableHold.
Web: Add IE In Setup
CLI: add-ie-in-setup
[IpProfile_AddIEInSetup] Defines an optional Information Element (IE) data (in hex
format) which is added to ISDN Setup messages. For
example, to add IE '0x20,0x02,0x00,0xe1', enter the value
"200200e1".
Notes:

This IE is sent from the Trunk Group IDs that are defined
by the SendIEonTG parameter .

You can configure different IE data for Trunk Groups by
configuring this parameter for different IP Profiles and
then assigning the required IP Profile ID in the Inbound IP
Routing table (PSTNPrefix).

This 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.
Web: QSIG Tunneling
CLI: enable-qsig-tunneling
[IpProfile_EnableQSIGTunneling] 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.
Notes:

QSIG tunneling must be enabled on originating and
terminating devices.

To enable this function, set the
