Make sure your timing is being set correctly on the t1 from the telco.
 I had the exact same problem before I realized I was doing things
wrong.

Timing is set in the /etc/zaptel.conf file in the span section:
# My FXS channel bank uses internal timing
span=1,0,0,esf,b8zs
             ^
# SPAN 2 is the T1 to telco set it to get timing here
span=2,1,0,esf,b8zs
              ^

Once I fixed this, nearly all my fax troubles have gone away.
