That’s correct. I haven’t renewed EPM for years now. The reason is because my organization uses Sangoma phones. Sangoma phones can be provisioned without paying for EPM. Please let me know if that’s accurate or not. Should I buy an update to EPM?
I should add that now all S500 phones have Follow Me Enabled (automatically). When I try to disable them, it says “failed to load xml files”. I suspect that it’s a problem with the phone apps.
Okay, since you’ve paid for Endpoint Manager you have two options. You can renew the maintenance in the normal way and continue to get updates once again. If you have no need of the paid features (i.e. you don’t need to provision non-sangoma phones) then you can open a billing and customer service ticket and request to have the paid EPM license for your deployment abandoned, and then use it as if you’ve never paid for it. https://wiki.freepbx.org/display/FPAS/How+To+Open+A+Support+Ticket
