Power Cycle Desk Phones (Reboot/Restart)

Restart a desk phone to clear temporary registration, audio, or display issues without erasing settings.

Restarting a desk phone can help clear temporary registration, audio, or display issues. A restart does not remove phone settings or erase registered lines.

This is different from a factory reset, which clears device settings and should only be done when you intend to reconfigure the phone.
