User's Manual 74. Configuration Parameters Reference
board 3-way conference calls, by using the
MaxInBoardConferenceCalls parameter.

[3] Huawei Media Server = The conference is managed by an
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.

[ConferenceCode]
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.
Conference ID
configure voip > gateway
dtmf-supp-service supp-
service-settings > conf-id
[ConferenceID]
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.
Use Different RTP port

configure voip > sip-
definition settings > dfrnt-
port-after-hold
[UseDifferentRTPportAfter
Hold]
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
