Tonight beginning at 11:59PM PDT we will be performing a software upgrade of various components of our voice network in Santa Rosa. No service impact is expected from this, but users may experience sign-outs/session time-outs on voice portals during the maintenance. Estimated time is around ~1 hour.

Update: Maintenance is now complete

Please see https://forums.sonic.net/viewtopic.php?f=14&t=2992 to see the maintenance was not non-intrusive. I experienced the same thing: device not registered and the Phone LED on the Grandstream was off. A power cycle restored service.
