Are you using FQDN or IP address to auto provision? Is the phone in office or remote?

 

[Tomtom78]

The phone is in remote and I am using IP... now, after one night the phone appears registered and works however online appears as: UNPROVISIONED

How did you provision the phone? Did you use RPS, copied the provisioning link into the phone or did you manually provision the phone?
