I’ve been successfully running 16 lines on an internal only network. but about a week ago (30 days later). Some of my phones came up with the error below. They are all Avaya 1120e. I saw that it was a TLS configuration issue, but does anyone have tips on how to fix this. I’m not sure if it is freepbx or specific to the phones.
