User's Manual
setting of the ConferenceCode parameter is overridden.
Defines the Conference Identification string.
The valid value is a string of up to 16 characters. The default is
"conf".
The device uses this identifier in the Conference-initiating INVITE
that is sent to the media server when the Enable3WayConference
parameter is set to 1.
Enables the use of different RTP ports for the two calls involved in a
three-way conference call made by the FXS endpoint in the initial
outgoing INVITE requests.

[0] Disable = (Default) The FXS endpoint makes the first and
second calls on the same RTP port in the initial outgoing INVITE
request. If a three-way conference is then made, the device
sends a re-INVITE to the held call to retrieve it and to change the
RTP port to a different port number.
For example: A first calls B on port 6000 and places B on hold. A
then calls C, also on port 6000. The device sends a re-INVITE to
the held call to retrieve it and changes the port to 6010.

[1] Enable = The FXS endpoint makes the first and second calls
on different RTP ports in the initial outgoing INVITE request. If a
three-way conference is then made, the device sends a re-
INVITE to the held call to retrieve it, without changing the port of
the held call.
For example: A first calls B on port 6000 and places B on hold. A
then calls C on port 6010. The device sends a re-INVITE to the
held call to retrieve it (without changing the port, i.e., remains
6010).
Note:

When this feature is enabled and only one RTP port is available,
only one call can be made by the FXS endpoint, as there is no
free RTP port for a second call.

When this feature is enabled and you are using the Call Forking
feature, every forked call is sent with a different RTP port. As the
device can fork a call to up to 10 destinations, the device
requires at least 10 free RTP ports.

The parameter is applicable only to FXS interfaces.
Global parameter defining call priority handling.
You can also configure the functionality per specific calls, using
Tel Profiles (TelProfile_CallPriorityMode). For a detailed
description of the parameter and for configuring the functionality
in the Tel Profiles table, see 'Configuring Tel Profiles' on page
