Hello, I am testing the FreeSWITCH mod_spandsp module. I have got a gateway registered in FreeSWITCH which supports fax and using the following command to send the fax, but It always ended up with the "result (49) The call dropped prematurely" error. Also if I remove fax_enable_t38 variables, it's giving "Reinvite Codec Error!". I have pastebin the entire log in http://pastebin.freeswitch.org/15394. originate {absolute_codec_string='PCMU,PCMA', fax_enable_t38=true,fax_enable_t38_request=true}sofia/gateway/Pulse/1XXXXXXXXXX &txfax(/var/www/html/faxtest/docs/15Feb2011103600.pdf.tiff) Please assist. Thanks, Rex -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/The-call-dropped-prematurely-e... Sent from the freeswitch-users mailing list archive at Nabble.com.
