Hi,
Firs things first, i have set up a lot of these phones externally and i find that they do work quite often, however from 3cx perspective we recommend using the 3CX sip proxy tunnel releaving you of any grief.
First things first, I realise you been trough most of these steps but I will go trough them again.
1. Ensure you have done all the correct port fowarding on your router. Any SIP alg on your router must be disabled.

2. Run the firewall checker and ensure there are no warnings.
3. Paste screenshots of the setting of your device blanking out your ips and usernames please or i will delete your post immediatley for your own safety.
4. If all else failes, wireshark is your friend, pm me with a link to a capture and I will help you, DO not publicy display this link or again I will delete your post for your own safety.
