6.8.7 Three-Way Conferencing Parameters
The three-way conferencing parameters are described in the table below.
Table 6-39: Three-Way Conferencing Parameters
Parameter Description
Enable 3-Way Conference Enables or disables the 3-Way Conference feature.
[Enable3WayConference]

[0]

Disable = Disable (default)
[1] Enable = Enables 3-way conferencing
Note:
3-Way Conference Mode
For this parameter to take effect, a device reset is
required.
Defines the mode of operation when the 3-Way Conference
feature is used.
[3WayConferenceMode]

[0]

AudioCodes Media Server = 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.
(Default)
[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 3-way conference. The
conference is established on the device without the need
for an external Conference server. The device utilizes
resources from idle ports to establish the conference call.
You can limit the number of simultaneous, on-board 3-way
conference calls, by using the parameter
MaxInBoardConferenceCalls. In addition, you can
designate ports that can’t be used as a resource for on-
board, conference calls initiated by other ports, using the
parameter 3WayConfNoneAllocateablePorts.
Notes:

This parameter is applicable only to FXS interfaces.

When using an external conference server (i.e., options
[0] or [1] ), more than one three-way conference may be
supported (up to six).

Due to device hardware constraints, the on-board 3-way
conference mode (option 2) is currently not supported
when using SRTP.
