The Yealink SIP-T31P with Power Supply is the same dependable entry-level phone as the standard T31P, packaged with a power supply unit so it can be deployed in any location regardless of whether PoE is available. For small offices, home workers, or branch sites without PoE infrastructure, this bundle removes one less thing to think about during setup. The T31P supports two SIP lines, features a clear display, and delivers HD Voice quality on every call. The full-duplex speakerphone handles quick hands-free conversations reliably, and the phone is compatible with a wide range of SIP-based platforms and hosted VoIP providers. For businesses deploying phones at scale across multiple locations with varying infrastructure, the PSU bundle offers a consistent and predictable installation experience. It is a no-fuss phone for everyday communication, made even easier to roll out with the power supply included in the box.
