Call conferencing doesn't work

julienf28 · ‎07-15-2009

We have CCM 3.3 (i know, we are upgrading to the newer version of 7.X soon) and when we try to do a call conference with 3 people in the office, it just doesn't work. What service in CCM is this using?

IPVMS, try resetting the CFB from GUI, if it doesn't work bounce the service. I'm assuming you're using SW CFB, for HW CFB you might try no sccp/sccp

In version 6.0, i restart the service â€œCisco IP Voice Media Streaming Appâ€.

Enable CallManager detailed trace, you should find "out of resource" or simulator message.

Conferencing resource can be configured as a profile on the Voice Gateway if you have enough DSP resource. How to find out?

Do the "Max sess ?" under the "dspfarm profile 1 conference", you only need one!!

You can also do a "sho inv" - look at PBDM's.

Now add "Hardware conferance bridge" "GW-CNF" in CallManager and add to Resource Group for phones. Restart CallManager.

After Restart check CFB registration, and test.

If you still have problems add the transcoding profile using the same procedure you used for conferencing:

dspfarm profile 2 transcode
