Phones are dropping out and changing to URL calling is disabled, this is fixed with a restart

They are polycom IP 450’s if that matters, but they have all been dropping out and going to URL calling is disabled. I have everything updated on my server. Do you have any ideas? I need to get this fixed as soon as possible.

@tm1000 has anything changed in recent updates that would affect how phones are registering? I would like to get this issue resolved as soon as possible.

I do not and have never worked on Endpoint Manager. Tagging me doesn’t help with anything.

Who can I contact about the issue?

Commercial module support. Which is free if it’s a commercial module bug and not commercial module support. That or opening a bug on Those are the proper channels.
