[cisco-voip] CF off net low audio issue

[Ryan Ratliff]

Try 'show port voice' on the router and look at output attenuation on  
the outbound port and input gain on the inbound side.  You'll want to  
play with those to get the volume where you want it without  
introducing echo, etc.

I have several smaller physician offices that will forward their main

on FXO port 2 etc.

The problem I have is that the audio level the caller hears is greatly  
attenuated; almost beyond discernment.  However if I call the far end  
directly the call is very clear so it appears my router is the problem.

Anyone have any thoughts on this?
