Problem with freepbx Cisco SPA 303

Freepbx its online but when I try to provision the ip phones it wont connect to the PBX (Cisco SPA 303 phones ) the proxy is the correct IP of the PBX.

any ideas? I am getting error : FailedAuthenticate

Could be anything… I would start by making sure your extension/secret are correct

Then try to register from a soft client (ZoIPER)

Watch asterisk debug by logging in via ssh then ‘asterisk -rvvvvv’

Let me know what you find

Are you using Endpoint or Manual Config?
