[Asterisk-Users] Help! Zap echo on bridged calls

[JD Austin]

I've been going nuts lately trying to get rid of an annoying echo 
problem that makes my asterisk server unusable when clients try to call me.
Here's the breakdown of the issue  - Hoping that someone can throw me a 
clue:
My setup is as such:
Single AMD Athon machine with X100P clone card and voip through multiple 
providers .

    * Inbound calls through the X100P that do not bridge to voip are fine.
    * Outbound calls that do not bridge with the X100P are fine.
    * PSTN ->*->VOIP calls have so much echo on the called party side
      (sidetone) that it is almost impossible to have a conversation.

I've played with rxgain txgain, echocancelwhenbridged,etc nothing seems 
to work.  Yes Im completely restarting asterisk and running ztcfg.

Anyone figured this out?
Heres my zapata.conf :
