How do I change the provisioning server info on a remote device?

Hello,

I have a handful of remote devices that will need their provisioning server details changed in the next few weeks, problem is that I can’t physically get to them and I’ll have no one in the location to change the info for me at the time of change, so I need a way to remotely change the info on these devices.

How can I do this through the PBX?
