Did you manually , or auto-configure?
Is it local to the server, or using STUN, or behind an SBC?

the phone appears on the phone dashboard but it doesn't let me go into the settings.

Do you mean that it won't allow you to log into to GUI of the HT801 because the password may have changed?

Have you looked at the 3CX Activity log after a call attempt? I'm assuming that 3CX shows the extension as registered.

@isaiah c Firstly, follow the guide and upgrade the firmware if the device to 1.0.35.4 (as of this time).

Then factory reset the device, and reprovision it again from scratch as per the guide

Once it is provisioned and appears in your "Phones" page correctly indicating the correct extension number, you should now try and make a test call. Try ringing the voicemail extension (usually 999).

Does this work for you?
