See original post; Sangoma Phones, ATT Fiber Uverse, EdgeRouter Setup
So I was able after factory resetting the phone to go in and manually configure an extension. Which now registered. If I go into endpoint manager I see my configured endpoint with the MAC and it shows as registered and has the ping response time. The phone is set to auto provision with sangomas server, which I can see in sangomas portal the polling attempts.
However the phone STILL refuses to pull the actual configuration. Even after selecting the force phone to check configuration and update the phone will pop up saying its checking the config and it was successful but never actually pulls it.
The phone has Login Int, Login Ext and now Line 3 being the one I manually registered.
So does anyone have any ideas on what gives why the phone will no longer properly pull configuration? It started first as refusing to register any of the lines (as it had the existing configuration), eventually I factory reset the phone and in my original topic you can see more about the issues I had.
Also to note, I removed the edge router and I even now factory reset the ATT modem so its the factory settings so it should work no issue. The phone still refuses to pull any configuration
