I have a client we’re having some issues at. When I check Asterisk info > peers I see that their extensions randomly show UNREACHABLE.
-I have a poe switch and 5 phones on-site, connected to my cloud hosted fpbx.
-I have no control over their router (it’s managed by their IT vendor)
-they have a static ip
-their router is doing dhcp & nat
-cloud hosted fpbx 13, NAT set to yes on the extensions
Most of the time their extensions show OK, but sometimes a random phone will show UNREACHABLE.
Which causes that phone to not ring on an incoming call & is causing lots of frustration for me and the client. So outside of putting a fpbx on premise or getting them to get an additional static ip and I can separate phone/data lans & put in my own router, what are my options here? what else should I check
