to debug this, i wanted to look how a working T.38 transmission look
like, so setup two cw with spandsp6_pre10
[faxout] ;cw 1
exten => s,1,TxFAX(${FAXFILE},debug)
exten => s,n,Hangup
[faxin] ;cw 2
exten => 123,1,RxFAX(/tmp/faxfile.tiff,debug)
exten => 123,n,Hangup()
But the transmission always fail. On cw1:
Fax send not successful - result (14) Received bad response to DCS or training.
Log: http://callweaver.pastebin.com/m10782863
and cw2:
Fax receive not successful - result (13) Unexpected message received.
Log: http://callweaver.pastebin.com/m3140c592
Is spandsp's T.38 not compatible with spandsp's T.38?
