Most PRI setups in the US that I've delt with are esf.  My setup below:

#
# Zaptel Configuration File

span=1,1,0,esf,b8zs
defaultzone=us
loadzone=us
bchan=1-23
dchan=24


Zapata Configuration file
switchtype=national
context=pri
signalling=pri_cpe
group=1
echocancel=yes
echotraining=yes
echocancelwhenbridged=yes
rxgain=-1.0
txgain=-4.0
busydetect=no
callprogress=no
pridialplan=unknown
usercallerid=yes
callerid=asreceived
channel => 1-23

You'll see the b channels restart when the first come up:
