Hello I'm trying to isolate a issue have a few hundred polycom 331s that are located in seperate networks accross the US. Every few weeks, random phones will lose registration with the error "URL Call Disabled" however just simply rebooting the phone will allow it to register again. I've attempted to replicate this issue in my lab in every possible way to see if its the network causing this but the phones will re-register without having to reboot. I also noticed that during the error, the phones still have an internet connection. I'm stumped on why does it need to hard reboot to register successfully.
I attached the log file and config file (removed the auth details) however I copied a few lines below to show what happens before I reboot the phone.
