[Asterisk-Users] TxFax/SpanDSP problems

[Eric Wieling]

It would be VERY nice if TxFax exited with a non-zero return code if the
fax was not actually sent.  In the case of the problem with sending to
the Canon fax machine, this always returns "0":

$status = $AGI->exec("TxFAX", "$fax_filename|caller");
