Cisco SPA112 Factory Reset: Methods, Default Login, and Security Context
The Cisco SPA112 is a two-port analog telephone adapter that MSPs and VoIP admins still encounter regularly in the field. When you lose the password, inherit a used unit, or need to reprovision the device for a new SIP provider, a factory reset is the fastest path forward. This guide covers all three working reset methods (physical button, IVR code, and web interface), explains the SPA112 versus SPA122 IP address confusion that wastes time on nearly every first attempt, and documents the default login credentials after reset. It also covers the critical end-of-life and security context that most competing pages skip entirely.
