asterisk users - May 2004 - PRI to PRI fax pass through

Hi

I have Asterisk with two E100P cards
One connected to PSTN and other to my local PBX

I'm running into problem with faxes.

Faxes are connected to PBX and asterisk should  just bridge the fax call
from one span to another.

Problem is that even if the fax image reach the over end 90% the fax
receive the transsmit error.
Its happend for incomming (PSTN->asterisk->PBX->fx) and outgoung
(fax->PBX->asterisk->PSTN) directions

dial string include the c option (clear channel)

TRUNK_El=Zap/g1

exten => _[0 1-9].,1,SetCallerID(${MyPreffix}${CALLERIDNUM})
exten => _[0 1-9].,2,Dial(${Zap/g1}/$[EXTEN],100,c)
exten => _[0 1-9].,3,Congestion

And also i have sometimes the echo (even the echocansel is yes in
zapata.conf)
May be it related to the fax also?

Any ideas is appreciated

maybe slips ?  I had similar problem.
check timing parameter of  E100P (zaptel.conf),
check interrupts, sharing is not allowed  (/proc/interrupts)
my 0.02$
