[ktouati]

Hi Guys,
I'm having a non-obvious issue, i am using Fax for asterisk to receive faxes, so when i test using a website that send faxes it's working great: the fax is received and the fax2mail app is called and i get it in my email box. but when i try using a regular fax machine everything in logs (turned on debug) but all of the sudden a line appear saying:
Channel 0/1, span 1 got hangup request, cause 16
and then the fax2mail is not called for some reason and no fax received, can you help me guys with that?
thanks!!!

I'm having the exact same issue. The call is getting disconnected before the fax can complete. If I send a one page white piece of paper, then it makes it through before getting disconnected because of little to transmit. If I send a one page fax with content on it, it doesn't make it. Anyone have any ideas on this one?

You guys using T.38? What about a gateway from IP to analog? If so, which one? Also, have you tried forwarding from your email to the fax address on the asterisk box to rule out a protocol issue? Please include a little more info about the hardware you have in your config.
