[cisco-voip] Conference Failed between 2 CallManager Clusters

[Alan Su]

Hi Daniel, Matt:

The disconnection happened on the 2nd Conf pressed, I think it's caused by
the g711 issue like you guys mentioned. I'll try to setup a hardware
transcoder to fix it. Thanks a lot for your help~

Regards,
Alan
