[1]), a conference call with up to six participants can be 
established. 
  For local, on-board 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; 
Web: Max 3 Way Conference 
EMS: Max In Board Calls 
[MaxInBoardConferenceCalls] 
Defines 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] 
Defines 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. 
Web: Establish Conference Code 
EMS: Establish Code 
[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.
