Unified Communication 6; conference calls

[cris_jimenez]

I created a MRGL and added to the phone config setting and to the device pool.

however everytime I try to setup the conference call, I actually can do it, however I get busy tone on the phones that I'm trying to conference in

could you please help on how to fix this

If you have given a bandwidth limit in the location configuration setting of the phone, and if the call bandwidth exceeds this configured limit, the conferencing will fail. In order to resolve this issue, configure Unlimited Bandwidth in the Phone Location Configuration Settings.
