hello every body


i have problem in receiving fax from e1 lines. this is my scenario:


faxphone----ericson pbx ---e1----asterisk----sip-----zoiper-softphone


when i send fax from zoiper, i can receive it successfully on the faxphone but when i send fax from faxphone, i can not receive it on zoiper. i want do this just by using faxdetect option. when fax comes from faxphone, chan dahdi on asterisk detect fax and redirect to fax extension. in fax extension, i just dial sip peer which is connected to zoiper like this:

exten=>fax,1,Dial(SIP/peer-1/${EXTEN})


peer-1 is a sip peer which is defined in sip.conf like this:


[peer-1]
host=192.168.0.XX
type=peer
context=from-trunk
insecure=port,invite


i set debug messages and understand that sip channel can not identify fax and try to send it like a voice call (set rtp and other things exact a voice call). what is the problem? does chan dahdi should send something for sip to identify fax session? or something is wrong related to chan sip?

i struggle a lot but can not solve this problem. any comments or hints are really appreciated.
