Hello Friends
I Made new Implementation of IPT with CUCM 8.0 (Pub and 1 Sub) and H323 Gateway. Calls are working fine, But When I make Conference call Internally It fails. Suppose from Phone A I called Phone B, Phone B Answer Call. From Phone A I press Conference Button and Dial Phone C, phone C Answer the call, Now from Phone A I press Conference Button Again to have Conference it fails either all call dorp or it revert back to resume Call to Phone B.
Please advice
Thanks

Hello Abbas,
I faced a similar kind of issue with my CUCM 8.5. Call Manager service restart fixed the issue.
Thanks,

Abbas,
What are you using as a conference bridge? Are you using HW bridge or software (CUCM server)? If HW please post config.
Is your conference bridge registered?
Is it assigned to proper MRG
Is the MRGL with this MRG assigned to proper Device Pool?
What regions are used for the call?

If you are certian your CUCM configuration is proper, my only suggestion would be to look at CM SDI trace logs for reasons of the drop.
