external, third-party Conferencing server. The conference-
initiating INVITE sent by the device, uses only the ConferenceID
as the Request-URI. The Conferencing server sets the Contact
header of the 200 OK response to the actual unique identifier
(Conference URI) to be used by the participants. The
Conference URI is included in the URI of the REFER with a
Replaces header sent by the device to the Conferencing server.
The Conferencing server then sends an INVITE with a Replaces
header to the remote participants.
Note:

The parameter is applicable only to FXS and BRI interfaces.

Three-way conferencing using an external conference server is
supported only by FXS interfaces.

When using an external Conferencing server, a conference call
with up to six participants can be established.
Defines the maximum number of simultaneous, on-board three-way
conference calls.
The valid range is 0 to . The default is 2.
Note:

For enabling on-board, three-way conferencing, use the
3WayConferenceMode parameter.

The parameter is applicable only to FXS and BRI interfaces.
Defines the DTMF digit pattern, which upon detection generates the
conference call when three-way conferencing is enabled
(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".
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
