STUN Remote Phones Unregistered By 16.0.7 Update

[AE-IT]

I just applied the 16.0.7 update about 2 days ago and now the remote phones are unregistered. The web-admin portal for the phone says: [extension]@[FQDN] : Register Failed. Anyone else have this happen? I can't think of any changes that could cause this other than the 16.0.7 update two or three days ago.

Hi @AE-IT

Regardless of whether the phones worked previously, it would now be a good idea to revise the deployment since you are facing issues. STUN might sometimes work even without the correct settings in place, and then stop working later.
