I'm using Freephoneline and the outgoing calling ain't working. Incoming is fine. I noticed they have a new skin. But I also noticed it wasn't working before too for about a week. I got the new skin a few days ago. This should affect Fongo, Freephoneline and DellVoice.
For me seems to be working, I just did 1 test. I had problems with the registrations though. Few days ago a friend of mine told me he noticed his Asterisk is not registered to FPL. Reloading sip.conf didn't fix the problem, he had to restart Asterisk. When I've checked I had the same behavior and I also had to restart Asterisk to have FPL account registered.
