Good afternoon,

There has been no glitches, nor outages on our end in quite some time. Best bet would be if this continues to be an issue to open a support ticket for a more detailed look.

I've also bumped your nat keep alive to check every 5 minutes for connectivity. Basically if you are seeing "cannot connect to server" within the pap2's GUI, your local NAT / Firewall settings are probably blocking our re-registration request. Be sure to disable if active any SPI / ALG SIP firewall within your router as this type of Stateful Packet Inspection is well known to cause issues with VOIP services.

Cheers,
-James
