for T.30 it would need the audio file and you can decode it easy.

I would recommend a tcpdump trace and see what's happening. If transmission is via T.38, it's not too difficult to determine, what's happening there with Wireshark. In case if T.30 it's much more difficult of course.

a fax log would be nice to have ...

provide a log to pastebin pls.

in general "The call dropped prematurely" means, spandsp didn't "hear" far-end fax at all or it was a pure voice call on the other end.

Greetings list. 

I am using freeswitch to receive fax from DID numbers. But i see most of fax calls being failed due to " Timer T2 expired" and "The call dropped prematurely". I tried to enable fax debug but could not understand why it is happening. 

Could someone please help in out in understanding the reasons of these failures and how to over come these failures.

Using FreeSWITCH Version 1.6.19~64bit ( 64bit)

Best Regards.
