I have a client that just upgraded their on premise system to v20. They also have several hundred legacy unsupported phones. New supported phones are onsite and ready to be installed but I noticed that their provisioning url is http and not HTTP(s) .
- How do I force the system to change the provisioning url to be secure?
- And how do this without wrecking the provisioning on all of the old legacy phones until they are removed from service.
