This system (NS700) was installed within a local network and all phones (KX-NT553, approx. 12) have worked flawlessly for years on the internal network.
When the COVID-19 lock down happened, seven of the phones were deployed remotely and connected directly to the internet at each person's residence with several different ISPs. The IP addresses were updated and the phones generally work well. All required POEs and the POEs are of varying manufacturers. All deployed phones pass through the same firewall (Watchguard).
However, two of the seven deployed phones are regularly rebooting and the other five never reboot. More interestingly, the two that reboot always do so at or near the top of the hour (between X:55 and X:05). These two phones probably reboot 18-22 times a day always at or near the top of the hour. This is not random and the reboots will happen both during active calls or when the phone is idle.
Any thoughts?
