
If an ISDN phone user presses digits (e.g., for
interactive voice response / IVR applications such as
retrieving voice mail messages), ISDN Information
messages received by the device for each digit are
sent in the voice channel to the IP network as DTMF
signals, according to the settings of this parameter.

The corresponding global parameter is TxDTMFOption.
Defines the second preferred transmit DTMF negotiation
method. For a description, see
IpProfile_FirstTxDtmfOption (above).
Note: The corresponding global parameter is
TxDTMFOption
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.
Enables the Call Hold feature (analog interfaces) and
interworking of the Hold/Retrieve supplementary service
from ISDN PRI to SIP (digital interfaces). For analog: The
Call Hold feature allows users, connected to the device, to
place a call on hold (or remove from hold), using the
phone's Hook Flash button.

[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.

Analog interfaces: To use the call hold service, the
devices at both ends must support this option.

The corresponding global parameter is EnableHold.
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).
