The Yealink SIP-T43U with Power Supply is the same dependable 12-line Gigabit phone bundled with a power supply unit, making it straightforward to deploy in any location where Power over Ethernet is not available. Whether that is a home office, a small branch location, or an older building with legacy network infrastructure, this bundle removes the setup barrier entirely. The T43U offers 12 SIP lines, dual USB ports, Gigabit Ethernet, and HD Voice. It is a clean, well-built phone that handles a moderate to heavy call load without issue, and it supports Yealink’s expansion modules for users who need additional line keys or a larger button panel. Compatible with most major SIP-based platforms and hosted VoIP services, the T43U is easy to provision and straightforward to support. The included PSU simply extends its reach to more deployment scenarios without changing anything about the core calling experience.
