Parameter Description
3-Way Conference Mode
configure voip > gateway dtmf-
supp-service supp-service-
settings > 3w-conf-mode
[3WayConferenceMode]
Defines the mode of operation for three-way conferencing.
 [0] AudioCodes Media Server = (Default) The conference-
initiating INVITE sent by the device, uses the ConferenceID
concatenated with a unique identifier as the Request-URI. This
same Request-URI is set as the Refer-To header value in the
REFER messages that are sent to the two remote parties. This
conference mode is used when operating with AudioCodes
IPMedia conferencing server.
 [1] Non-AudioCodes Media Server = The conference-initiating
INVITE sent by the device, uses only the ConferenceID as the
Request-URI. The Conference server sets the Contact header of
the 200 OK response to the actual unique identifier (Conference
URI) to be used by the participants. This Conference URI is then
included by the device in the Refer-To header value in the
REFER messages sent by the device to the remote parties. The
remote parties join the conference by sending INVITE messages
to the conference using this conference URI.
 [2] On Board = On-board, three-way conference. The
conference is established on the device without the need of an
external Conference server. You can limit the number of
simultaneous, on-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.
