I've checked voip.freephoneline.ca with several Freephoneline numbers at different locations within Canada using different ISPs. Incoming calls are working on all of them, which means registration is working fine on that server for those numbers at 3:12 p.m. EST.
If you're continuing to experience issues with voip.freephoneline.ca, for SPA/PAP series ATAs, navigate to Line 1 (or whatever you're using for FPL)-->SIP settings, and change SIP Port to a random number between 30000 and 60000. Do this for security reasons (to help avoid SIP Scanners/hackers). Also, this step may help to temporarily address a corrupted NAT association that's developed between a router and ATA (if you're having registration issues, try selecting a new random port number in this range, and then reboot the ATA. If that works, you were dealing with a corrupted/stale NAT association in your router).
For Obihai ATAs, Navigate to Voice Services-->SP(FPL) Service-->X_UserAgentPort. X_UserAgentPort should be a random port number between 30000 and 60000. Just pick a port number in that range.
If you've already chose a random number in that range, choose a different number in that range. Save settings, and reboot the ATA. If that works, you were dealing with a corrupted/stale NAT association in your router.
If you're switching back to voip.freephoneline.ca at this point (from another server), you won't be able to check for NAT corruption. Registration should work at this point unless a temporary IP ban is in place due to too many registration attempts within a short interval when using voip.freephoneline.ca
Regardless, voip.freephonline.ca has been the least reliable proxy server over the past year. You may be happier using voip4.freephoneline.ca:6060 or voip2.freephoneline.ca.
