Yealink SIP-T29G IP VoIP Phone
The Yealink SIP-T29G was the flagship model in Yealink’s T2 IP phone series, built for executives and busy professionals needing a high-end desk phone with rich visual feedback and heavy multi-line capacity. It features a 4.3-inch 480×272-pixel colour TFT display with backlight, supports up to 16 SIP accounts, and offers 10 programmable line keys that expand to 27 features across three pages. Yealink Optima HD voice delivers wideband audio with echo cancellation and adaptive jitter buffering, while dual-port Gigabit Ethernet (with PoE on one port) keeps network performance fast. A built-in USB 2.0 port supports Bluetooth headset pairing via the BT40 dongle, Wi-Fi via the WF40 dongle, and USB call recording, and the phone can be expanded with up to 6 EXP20 modules to function as a full attendant console.
