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.

Yes turning off echo cancelling would be fatal. We have some serious echo going on here that I can not seem to track done. I am assuming it is just this old building. Maybe we can go ISDN or so but the dropped calls are rather bad.
