How in the hell does that make any sense?  are your normal incoming calls 
quiet too or just voicemail?

I am not sure I understand why the txgain/rxgain isn't fixing it without 
adding unacceptable echo...  this all seems very odd...  I mean for a test 
you should be able to dial an echo() application and have extremely quiet 
echoed audio... is this the case?

This is a HELL of a band-aid.
