Why won't my remote phone register?

Having problems registering remote phones, or can't access 3CX Company Phonebook on a remote phone?

Check to make sure your phone was provisioned with the remote 3CX provisioning URL. If you provisioned the phone on the local network, then moved the phone to the remote site, it most likely is using the local provisioning URL.

In this case, re-provision the phone using the remote provisioning URL.
