Problem Sending And Receiving Faxes

Hi list!

I installed Hylafax on a Ubuntu-Server 14.04. On this server runs Asterisk 11.7.0, too and it was configured like my own Asterisk server at home, but it does not work… πŸ™

So, I configured Asterisk to connect to Deutsche Telekom and it does!
Then I configured iaxmodem to speak with the Asterisk and it does, too.

But when I try to send or receive a Fax, it does NOT… I always get “no carrier detected” (if sending) or “Ring detected without successful handshake” (if receiving).

In Asterisk debug modus I can see (sending!):
