Hi Pros,

I am trying to utilize PVDM2-64 on 3825 Router for conference bridge. I have made all configs as per CCO Docs. But still I am unable to get it running.

When I configure SCCP, then create a profile for conferencing, it shows option for maximum sessions as 0 only. Due to that I am unable to no shutdown the profile.

I am attaching a show tech-support of the router. Please let me know if I am missing any commands or any specific sequence needs to be followed.


Regards,

Pratik

I see you have two E1s. Are you using both ? Your sh inventory output shows u have have 64 channel DSP and both E1s are configured. The problem here is that you dont have enough DSP resources for conferencing. If you are not using the second E1, try removing the pri-group command from that E1 controller and that should help!

Hi Sankar,


Thanks for the info. Worked like a charm. Didnt realize those DSPs are required for voice too...
