Yealink Network Technology Co., Ltd SIP-T31G VoIP phone classic gray

Essential VoIP desk phone

The Yealink SIP-T31G is a corded IP phone built for everyday business calls. It connects through dual-port Gigabit Ethernet and draws power over the network cable. A 2.3-inch graphical LCD with 132-by-64-pixel resolution and backlight shows caller details and menus clearly. The handset delivers Yealink HD Voice audio quality for natural conversation.

Suits small offices and remote desks

This model supports up to two SIP accounts and local five-way conferencing, making it a fit for teams that need basic multi-line handling. It also works with EHS wireless headsets for hands-free use. Buyers who need more than two lines, a colour display, or built-in Wi-Fi should look at other models. The phone is wall-mountable for flexible placement.

Steady performance on long calls

PoE power delivery removes the need for a separate adapter, so the device stays online during extended sessions without extra cables. Dual Gigabit ports pass network traffic through to a PC while the phone maintains its own connection. Opus codec support keeps voice quality consistent even when bandwidth varies. The monochrome LCD remains readable under continuous office lighting.
