installed the CUCM 7.1(3b)su2 patch and now when using the conf softkey the connected conference goes to mute status(or at least that is what it sounds like) when the 3 party is connected. Disconnect the 3rd party and the call is back to normal.

Hi Donna,
What version of CUCM did you upgrade from? Are all three parties IP phones on the CUCM? Do all 3 parties experience the same "dead air" when the conference begins? What types of IP phones are in use? What version of firmware are they running? Can it be reproduced with every conference call that's initiated or is the issue intermittent? What conference resources are available in the IP phone's MRG/MRGL?

I upgraded from 7.1.3.10000-11. Yes all phones are VOIP on the same CUCM. I have it on our lab system right now. I am using 7965, 7975 and 7911 phone. They all get the dead air. They only have one MRGL. When this happened I tried to upgrade there firmware. so it is 9.0.3.

Are the conference resources CUCM or IOS based? can you attach a screenshot of the conference resource page and point out which ones are configured on the IP phone's MRG/MRGL.

I can't tell from you images if the conference bridges are all registered. Another test you could do is remove the conference bridge from all MRG (Media Resource Group) and test it again. The next thing I would do is pull a detailed call manager trace if it still fails. When it fails does the conference just not setup, do you hear a busy (reorder tone), or do you see no conference bridge available on the phone?

Can you paste the IOS configuration for these CFB's? Since it would appear that at least two of these conference bridges are configured in IOS, it would be good to examine this configuration as well.

Thank you all for helping me. It was the MRGL, it got removed from the phones. As soon
as I put it all back everything worked.
HAve a great day!
