asterisk users - Sep 2005 - Zap calls dropping just after answer

I've got a problem w/ zap calls being dropped right after they are
answered.  I have a log file:

http://pastebin.com/368526

Everything looks OK except for the 

DEBUG[25563] chan_zap.c: Exception on 9, channel 1

that seems to come up quite often.  As soon as the other end of the Zap
answers (my cell phone), and I can even hear a half second of noise, the
line goes dead and gets hungup.

In my case, Zap/1 is the first channel of a 24 channel T1 line to a
Fujitsu PBX.  All seems configured right as I can dial out and the cell
phone will ring.  This is very frustrating, can anybody help out w/
this?

This was solved.  My T1 link to the PBX needed to use em signaling
instead of fxs_ks.
