Kyrocera DuraForce Pro fails to register on 3CX 15.5.346.651

[matthew83]

I have 100+ multi model phones running on our PBX. Only the Kyrocera DuraForce Pro's are broken on this version. Any help would be greatly appreciated.

The App comes up and looks like its trying to register but never does. I can reboot the phone pull up 3cx and get it to register once. Sometimes. Any help would be greatly appreciated. Thank you.

I just downloaded the latest Beta hoping that would fix my issue and it does not.

I doubt this is related to the specific brand and phone. Can you tell me a bit about this extension's settings? Are you using TLS, UDP or TCP in this extension's provisioning settings on the PBX?
