[Asterisk-Users] Random disconnect of calls

[Chris A. Icide]

This was happening to me as well.

What finally fixed it was disabling echo cancelling on the X100P cards in 
the zapata.conf files.

However this resulted in a horrid echo on my cisco phone when I was using a 
line attached via one of my x100P cards.

So I went back and re-enabled echo cancelling and set echotraining=yes.

I've had much better luck with, however I still get a dropped call now and 
then.
