Executive IP Phone for Professionals

The Yealink SIP-T46S-SFB is an executive IP phone built for Microsoft Skype for Business environments. It targets busy executives, sales professionals and front-desk staff who need a familiar, high-resolution interface. The handset supports USB Bluetooth connectivity for mobile call switching and can pair with the Yealink EXP40 Expansion Module for up to 240 additional contacts. Its Optima HD technology and SILK speech codec aim to simplify daily workflows.

Wired Gigabit Network with Dual Ports

Connectivity relies on two RJ-45 ports providing Gigabit wired network access and Power over Ethernet support. The phone operates over cable using SIP, SIP v2, IPv4 and IPv6 protocols. Wireless capability is limited to Bluetooth for peripheral pairing only; there is no Wi-Fi radio. Caller ID and speakerphone functions are integrated, but all core telephony traffic stays on the wired Ethernet infrastructure.

Upgrade from T46G for Skype for Business Users

This model replaces the older T46G with a faster interface and a richer 4.3-inch colour TFT display. The jump is worthwhile for organisations standardised on Skype for Business who need the native on-screen interface and improved overall performance. Buyers who require Wi-Fi connectivity, a different UC platform or a non-executive feature set should consider other options.
