I am using a default configuration on my voice-port. Since my PBX is connected to a Cisco Router via a PRI, would I need to modify the "input gain" or "output attenutation" ? For inbound and outbound calls voice quality is great, and I hear no echo, I am just having this issue with a conference or transfer out of the PBX.
