I hope you might give me some hints on how to find where my configuration is wrong, I am new to Asterisk and do not know, how to find the problem.
Running Asterisk (version: 126.96.36.199~dfsg-3) on Debian Wheezy. On the same maschine: hylafax fax server. I want hylafax to use t38modem (a virtual T.38 modem) for sending faxes. t38modem schould connect to asterisk on the same host.
If hylafax sends a fax it should use t38modem which ist connected to asterisk. Asterik is expected to establish an outbound connection to my SIP provider which supports T38. The asterisk box is behind nat.
For some reason, t38modem tells hylafax the line is BUSY so there is no fax send. I don’t know why there is a busy signal, maybe the call forwarding configuration is wrong, maybe the registration on my SIP provider fails, maybe ….?
I simply don’t know how to debug what’s going on. If Asterix trying to establish an outgoing connection … Maybe you can help to enlighten me 🙂
