[Asterisk-Users] TxFax/SpanDSP problems

[Serge Oleinikov]

Hi Eric !
I have the same problem with Canon fax mashine as you have.  I have wrote an
email to Steve (developer of spandsp) some weeks ago and got no answer how
to fix the problem :(
Looks like connection was dropped by fax mashine without any reason
