Hi
I have changed NSE to REINVITE on ATA. Now there is word 're-invite' in
logs, so something changed. But fax is still not working.
I did both directions.
Receiving fax from ISDN CAPI --> ATA --> fax:
http://marek.terminus.sk/cw/full_2_in.gz
http://marek.terminus.sk/cw/callweaver_incoming_fax_2_in.tcpdump.gz
Sending fax from Fax machine --> ATA --> ISDN CAPI
http://marek.terminus.sk/cw/full_2_out.gz
http://marek.terminus.sk/cw/callweaver_incoming_fax_2_out.tcpdump.gz
When I was sending fax I observer interesting fact. I have asterisk on
receiving side with NVBackgroundDetect but call was not detected as fax. I
did the same fax sending before but instead of callweaver I had asterisk.
In that case receiving asterisk detected fax with NVBackgroundDetect. I
have filling I cannot get rid of that there is signal somehow degraded
when using callweaver. Also when I tried BackgroundDetect on callweaver -
dtmf and fax detection was very very unreliable. With NVBackgroundDetect
and asterisk it works 100% reliable. Same machine, same environment, same
configuration, only one difference: with asterisk I use mISDN, with
Callweaver CAPI.
Best Regards
Marek
