What kind of VPN connects the two sites?
The new Firewall is a Fortigate unit. We connect via the Fortigate client software.

That's the first clue that something is wrong. Fortigate are very problematic and undocumented.

You said this was over a VPN? When they disconnect are you able to ping the phones from the PBX? How are the phones configured, do you reference the PBX by domain name or by IP address?
-
Is thew PBX on site or hosted? That was not clear.

PBX is not hosted by a third party, but it is hosted by another division of the same company. So it acts like hosted to the site with the registration problems. It is an "on premises" PBX across the country with the phones registering over the VPN.

Phones are configured to use DNS name for the PBX server in the SIPserver. However both name and IP have been tried.

According to the "hosting site", their network tooling says that there is packet loss over their site to site connection.
-
using the webGUI on one phone, just pushed a reboot.
Registration failed after restart.

So it seems to be network related then. So this isn't really a PBX or SIP registration problem something funky is going on over the wire.

I call this done. Not the problem of the PBX.

Can you run this for a longer period and see what the loss rate is? Something like 100 or 500 packets?

Is there still packet loss on the line according to the hosting site? If there is that would be where I would start. It doesn't seem like the PBX or phones are the issue.
