I have CUCM 10.5 and a Cisco 2921 ISR with a PVDM3. I have working conference audio and video, as well as transcoding and MTP. These profiles on the CUBE are registered in CUCM. I configured video conferencing last and I have a PVDM 128 however I only have enough resources allocated to complete maximum 1 session, 4 participants in a video conference.
We can set up 8 participants in a audio only conference and I can have multiple sessions on audio only conferences.
I done a test with 4 video endpoints, desk phones and Jabber. Experience was good. However what if we only want an audio conference with up to 8 people? I found that since video endpoints will start video automatically this will begin as a video conference. When we reach 4 participants this is our limit. When I try to add a 5th person in to the conference, my expectation was that video will be dropped and the 5th person will join and all participants will now only have audio, and no video at all. However the experience was that I cannot add a 5th person.
What is the best way forward? It seems enabling Video conf. removes support for audio only conferences.. Is there a way to escalate to audio only conferences using the ISR?
