We have had to take down our Polycom and Poly provisioning due to emergency maintenance. Polycom phones attempting to provision will fail. All other supported phone manufacturers should work as expected. Update 12/18/25 10:03 AM: We continue to work on the issue and expect to have the Polycom provisioning server back online within 24 hours.
