T46S won't register
I got a brand new T46S yesterday that doesn't register with FreePBX, while a new set of W60P do. I'm also able to connect using a T28 and via a SIP app on my iPhone, so I'm certain the account info is correct. I have tried factory resetting the device, nothing works.

How to troubleshoot?

Hi,

Below are some options for what to do:
- Maybe the phone IP address is blacklisted in FreePBX?
- Replace the Lydis firmware with the International one?
- Check the power supply of the phone, try not to use PoE.
Kind regards,
Frank.

It was a NAT issue, changing the default SIP port solved the issue.
