Sending fax

Hello,

I’ve tried to send fax using Asterisk with SpanDSP(txfax), but unfortunately it doesn’t work. I am able to recive fax. When I put all needed information info fax.call file, I am able to hear ringing destination phone/fax, but when I hang up it, I hear only silence(= doesn’t hear anything:)). I use g711a codec.

Thank you
