User's Manual
(Enable3WayConference is set to 1).
The valid range is a 25-character string. The default is "!" (Hook-
Flash).
Note: If the FlashKeysSequenceStyle parameter is set to 1 or 2,
the 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).
Notes:

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.

This parameter is applicable only to FXS interfaces.
Defines priority call handling, for all calls.
