Asterisk fax - receives just half of the page

Postby asilem87 » Wed Aug 12, 2015 6:28 am

Hi all,

I have strange problem that I can not solve and I need help. I have asterisk 11.3 and centos 6.5. I am connected to my provider via SIP trunk, and he supports t.38. I configured ciscoSPA232D ATA Line and connected it to my Asterisk PBX. I also configured extensions, incoming and outgoing calls etc. and everything is working. However, I am able to send faxes to the remote machine but I have problems with receiving faxes. I tried to receive fax with different fax machines but I got just half of the page ! I also try to send from different fax numbers and the sittuation is same, I receive just half of the page. I am not expert with fax debbuging but from the wireshark trace EOP is missing . I tried to upload screenshots but I've got could not upload attachment message. If you need additional information please let me know I can add sip debug or something similar.
