Key Features
Dual-Port Gigabit Ethernet: Equipped with two 10/100/1000 Mbps ports (LAN and PC passthrough) to connect a workstation directly through the phone without bottlenecking 1Gbps office network speeds.
Integrated Power over Ethernet (PoE): IEEE 802.3af Class 1 PoE compliance enables single-cable power and data deployment (Note: AC power adapter sold separately).
Dual VoIP Account Support: Manage up to 2 SIP accounts simultaneously with dedicated programmable line keys and LED status indicators.
Yealink HD Voice & Smart Noise Filtering: Full-duplex hands-free speakerphone with Acoustic Echo Cancellation (AEC) and Opus codec support eliminates background office chatter.
Local 5-Way Conferencing: Host instant multi-party team calls directly from the handset without requiring an external conference bridge.
EHS Wireless Headset Ready: Dedicated RJ9 headset port with Electronic Hook Switch (EHS) support for seamless hands-free multitasking.
• Performance / Technology
Powered by Yealink's upgraded T3 series computing architecture, the SIP-T31G delivers fast response times during call transfers, directory lookups, and multi-line switching. Industry-leading Smart Noise Filtering Technology actively suppresses non-human background noise—such as keyboard typing, air conditioning, or nearby conversations—while wideband audio codecs (Opus, G.722) ensure lifelike voice reproduction.
• Design & Ergonomics
Crafted in a professional Classic Grey finish, the SIP-T31G features an ergonomic handset, tactile keypad, and a two-angle adjustable desktop stand (plus wall-mounting capability) to eliminate screen glare under bright office lighting. Context-sensitive soft keys and a dedicated 5-way navigation cluster make browsing the 1,000-entry local phonebook effortless.
• Compatibility / Use Cases
Running on Yealink Unified Firmware and compatible with the Yealink Device Management Platform (YDMP/YMCS), this IP phone supports zero-touch auto-provisioning for rapid IT rollouts. It integrates seamlessly with major IP-PBX and hosted VoIP platforms—including 3CX, Yeastar, Grandstream UCM, Asterisk, and FreePBX—making it ideal for corporate branch desks, reception areas, retail counters, and home offices.
• Why This Product Stands Out
Unlike standard Fast Ethernet (10/100 Mbps) entry-level VoIP phones that throttle the internet speed of the PC plugged behind them, the Yealink SIP-T31G provides full Gigabit Ethernet passthrough. It gives businesses an affordable, future-proof desktop telephony endpoint that preserves network throughput while delivering executive-level HD audio.
