Hi,
I'm trying out the FPL PC desktop app to see if the call quality and reliability is sufficient for me to dump Bell and go with FPL or Fongo. When I run the built-in connection test from the app, the call service reports as OK, but the data transfer fails with the message "unable to send/receive sound data! Port 13000 should be available." Despite getting this error, I can both send and receive calls with the desktop app and the call quality is good, no dropouts or choppiness in the few tests of it run so far. I have tested my internet connection with a few VoIP test tools and it passes with flying colours.
I tried opening the 13000 UDP port manually in my Windows XP firewall, it made no difference. I do have the SIP ALG running on my Dlink DIR 655 router, but it does not interfere with calls so far. Can I safely ignore this test failure and feel confident Fongo or FPL is going to work for me?
