Of course i use Wireshark and i see T.38 traffic but it isn't clear to me why the fax fails every time. I would like to know if there are T.38 tools/plugins that analyze a .pcap file more thorough.<br><br>In my setup the analogue fax device and the ATA are near each other at the customer site. The ATA connects (via T.38) to the Asterisk server which is in a datacentre with the Cisco PGW. The PGW is connected to the public telephone network.<br><br>Has anyone experience with sending T.38 fax messages between Asterisk and a Cisco PGW? </body>
