Support essential office calling with a desk phone built for clarity, speed, and straightforward deployment. The Yealink SIP T31G pairs 2 SIP lines with HD voice and Opus codec support, giving users cleaner audio for routine business conversations and call handling. Dual-port Gigabit Ethernet keeps the phone from becoming a network bottleneck, while PoE support reduces cable clutter at the desk. This model is a practical fit for organizations that want a capable endpoint without paying for features they will not use. The 2.3-inch graphical LCD with backlight improves readability in varied lighting, and the local 5-way conferencing feature supports small team collaboration from the handset. EHS support adds compatibility with wireless headsets for users who need hands-free operation. With unified firmware, support for YDMP/YMCS, and a stand with two adjustable angles, the SIP T31G is designed for managed environments where consistency matters. It also supports wall mounting, making it easier to deploy across reception areas, shared workstations, and standard office desks.
