Parameter Description
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. 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 MaxInBoardConferenceCalls
parameter. 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
3WayConfNoneAllocateablePorts parameter.
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).
Currently, the on-board 3-way conference mode (option 2)
is not supported when using SRTP.
For local, onboard three-way conferencing (option [2]) on
MP-112, the following additional parameter settings must
be made:
EnableIPMediaChannels = 1
[ IPMediaChannels ]
FORMAT IPMediaChannels_Index =
IPMediaChannels_ModuleID,
IPMediaChannels_DSPChannelsReserved;
IPMediaChannels 0 = 1, 2;
[ \IPMediaChannels ]
Web: Max 3 Way Conference On
Board Calls
EMS: Max In Board Calls
[MaxInBoardConferenceCalls]
Determines the maximum number of simultaneous, on-board
three-way conference calls.
The valid range is 0 to 2. The default is 2.
Notes:
For enabling on-board, three-way conferencing, use the
3WayConferenceMode parameter.
This parameter is applicable only to FXS interfaces.
Web: Three Way Conference Non
Allocatable Ports
EMS: Non Allocateable Port Number
[3WayConfNoneAllocateablePorts]
Determines the ports that are not allocated as resources for
on-board three-way conference calls that are initiated by other
ports. Ports that are not configured with this parameter (and
that are idle) are used by the device as a resource for
establishing these type of conference calls.
The valid range is up to 8 ports. To add a range of ports, use
the comma separator. For example, for not allowing the use of
ports 2, 4 and 8 as resources, enter the following value: 2,4,8.
The order of the entered values is not relevant (i.e., the
example above can be entered as 8,2,4). The default is 0.
Notes:
To enable on-board, three-way conferencing, use the
3WayConferenceMode and MaxInBoardConferenceCalls
parameters.
This parameter is applicable only to FXS interfaces.
