The main office has CCM 5.1.3
The branch office has Avaya PBX.
The avaya phone system is added as a H.323 gateway in the CCM and both the phone systems are integrated using H.323.
Everything is working fine except that the branch office users are complaining that the volume(decibel) level of the call is very low.
Is there a setting on the CCM to tweak the volume level of the call outbound a H.323 gateway?
Thanks in Advance.
