I'm working now, but if you look at the forums you will see many people complaining of incoming calls going directly to voicemail. That was happening to me and when troubleshooting I found two different scenario's:
1: Incoming Invite would be received from a server other than the one to which I was registered (it appears FPL has about 5 servers or so in the mix now). Asterisk would of course reject this call as coming from an unknown source.
2: Incoming call would not make it to Asterisk at all with nothing being seen at the firewall (as proved with a Wireshark capture) and a call failure message being logged in my FPL CDR logs (and the Portal showed my line as registered).
At no time with either of these scenario's would the FPL staff admit there was a problem, and they still won't. I've also been informed, for now, that they have rolled back to a 1 server solution, obviously showing they were having problems implementing load balancing/redundancy. By the way, anyone seen the new requirements/demands that they are placing on 3rd party devices?
