54.3. CTIMIX - Conference

The CTIMIX module enables conferences with any number of participants.

The Abilis supports various way of conference:

The Abilis provides system messages for Basic Conference, that can be changed by administrator, see Section 63.18, “Mixer / conference”.

[Note]Note

In a simplified and permanent conference the messages aren't played.

[Important]Important

The CTIMIX resource requires the SOFT-PBX licence.

[Tip]Tip

Interesting chapter: Section 75.22, “How to configure a Conference”.

54.3.1. Activating the CTIMIX resource

Add the resource to the Abilis system with the following command.

[09:08:14] ABILIS_CPX:a res:ctimix

COMMAND EXECUTED

The CTIMIX resource may already exist in the system, but may not yet be active. Set it active with the command:

[09:10:00] ABILIS_CPX:s act res:ctimix

COMMAND EXECUTED
[Caution]Caution

You must restart the Abilis to make the resource running (use the command warm start to reboot the Abilis) after adding or setting the CTIMIX active.

[Tip]Tip

If the CTIMIX resource is activated and the CTIAS resource isn't, Abilis automatically adds the CTIAS resource:

[12:11:11] ABILIS_CPX:a res:ctimix

COMMAND EXECUTED (ADDED ALSO RES:CtiAs)
[12:15:48] ABILIS_CPX:s p ctimix act:yes

COMMAND EXECUTED

[12:15:56] ABILIS_CPX:d p ctimix

[Important]Important

By default, the sesnum parameter is 3 and offers the conference only between 3 participants, for more participants is needed to increase it.

An important parameter is ROOM-ID, that shows the conference ID for a basic conference (in this case 2222). If the conference is permanent the ROOM-ID have P-x format (in this example P-1).

54.3.3.2. CTIMIX statistics

The following command is used to display the statistics of the CTIVM resource:

d s ctimix / d se ctimix

It shows the statistics of the CTIMIX resource such as the total number of successfully calls (CALL-SUCC), the total number of failed calls (CALL-FAIL), the total duration of conference (CALL-TIME), the number of created conferences (CREATE), etc.

The calls from participants have to be routed to CTIMIX by means of CTI Routing.

[Note]Note

For a simplified conference isn't needed to configure a CTI routing.
