Yealink SIP-T23G Gigabit IP Phone

The Yealink SIP-T23G is a cost-effective business IP phone built for small to large office environments needing solid multi-line calling without a complex interface. It features a 132 x 64-pixel graphical LCD, supports up to 3 SIP accounts, and includes 3 line keys with dual-colour LEDs for busy lamp field, line appearance, call park, and call transfer indication. Yealink HD voice technology, backed by echo cancellation and adaptive jitter buffer, delivers clear wideband audio through the handset or speakerphone. A dual-port Gigabit Ethernet switch supports fast network performance, the phone runs on PoE, and flexible provisioning is available via FTP, TFTP, HTTP, or HTTPS for straightforward IT deployment.

Important: this product has reached End-of-Life. Yealink discontinued the T23G for sale on September 30, 2021. It is no longer manufactured or actively supported by Yealink, and buyers should treat any available stock as legacy or refurbished inventory rather than a current product. The manufacturer’s recommended replacement is the Yealink T33G.
