Yealink SIP-T31P VoIP phone

The Yealink SIP-T31P is a corded IP phone designed for office users who need reliable voice-over-IP communication. It supports up to two SIP accounts and delivers Yealink HD Voice quality. A 2.3-inch graphical LCD with 132x64-pixel resolution and backlight provides clear call information. The classic gray handset is wall mountable for flexible desk placement.

Upgrade from basic analog handsets

This phone replaces traditional analogue handsets by adding dual 10/100 Ethernet ports and 802.3af PoE support for single-cable deployment. The jump is worth it when a business requires Opus codec support and local 5-way conferencing without an external bridge. It also adds EHS wireless headset compatibility for hands-free operation. Buyers who need more than two SIP accounts or gigabit network throughput should consider other models.

Sustained call handling

Under continuous use the dual-port 10/100 switch maintains stable connectivity for both the phone and a daisy-chained PC. PoE power delivery eliminates separate adapter clutter during long workdays. The graphical display remains legible during extended sessions thanks to its backlight. Local conferencing performance stays consistent without relying on server-side resources.

Questions about this item

What wall-mount spacing does the SIP-T31P need?

The phone is wall-mountable and uses the standard 100 mm centre-to-centre hole pattern found on most wall plates.

Which Ethernet port should the LAN cable use during setup?

Plug the network cable into the LAN port; the PC port is for daisy-chaining a computer and will not provide network access to the phone itself.

How often should the 2.3-inch graphical display be cleaned?

Wipe the 132 x 64 pixel LCD with a dry microfibre cloth whenever dust or fingerprints appear; no internal maintenance is required.
