16-Line Gigabit SIP Phone with 4.3-Inch Color Display, Dual USB 2.0 Ports for Bluetooth and WiFi Adapters, PoE, and EXP43 Expansion Module Support
The Yealink SIP-T46U (1301203) is a 16-line Gigabit IP phone with a 4.3-inch color display at 480x272 resolution, dual USB 2.0 ports for Bluetooth adapters, WiFi dongles, USB headsets, and call recording, and Yealink Optima HD Voice with Opus codec for superior audio clarity across varying network conditions. Dual-port Gigabit Ethernet with built-in PoE provides high-speed wired connectivity with PC passthrough and powers the phone directly from the network switch.
The SIP-T46U steps up from the T43U with a larger 4.3-inch color display, 16 SIP accounts, Gigabit Ethernet, and 27 programmable DSS keys across three pages for expanded speed dial and BLF monitoring. The phone shares the T4U series' dual USB architecture, dual firmware images for failsafe upgrades, and unified firmware across the T4U lineup, and deploys through Yealink's Redirection and Provisioning Service for zero-touch provisioning at scale.
Where the SIP-T46U Fits
- Executive and professional offices where 16 SIP accounts handle multi-line call management across departments and clients, the 4.3-inch color display provides clear visual call control with color-coded line identification, and dual USB ports add Bluetooth headset pairing and WiFi connectivity through adapters without sacrificing either port
- High-volume call environments where up to three EXP43 expansion modules add up to 180 programmable keys with LCD display and LED indicators for BLF monitoring, speed dial, and line management, and 27 built-in DSS keys across three pages handle direct station assignments
- Managed Gigabit VoIP fleets where dual-port Gigabit Ethernet with PC passthrough provides full network speed at every desk, zero-touch provisioning through Yealink's RPS handles deployment without manual configuration, and unified T4U firmware simplifies maintenance across all T4U models in the organization
What the SIP-T46U Delivers
- 4.3-Inch Color Display: 480x272 resolution color LCD with backlight provides visual call management, directory search, and line status for up to 16 SIP accounts with color-coded line identification. Three pages of 27 programmable DSS keys use paperless labels for speed dial, BLF, and custom function assignments.
- Dual USB 2.0 Ports: Two USB ports support any combination of two accessories simultaneously, including BT41 Bluetooth adapter for wireless headset pairing, WF40/WF50 WiFi dongle for wireless network connectivity, USB headset for hands-free operation, and USB flash drive for call recording.
- 16 SIP Accounts with Optima HD Voice: Registers up to sixteen independent SIP lines for multi-department call handling on a single phone. Yealink Optima HD Voice with Opus codec delivers wideband audio that adapts to network bandwidth for clear conversations on any connection quality.
- Gigabit Ethernet with PoE: Dual-port Gigabit Ethernet with PC passthrough and built-in PoE for single-cable installation from the network switch. SIP over TLS/SSL provides secure transport for enterprise environments.
- EXP43 Expansion Module Support: Connects up to three Yealink EXP43 expansion modules for up to 180 additional programmable keys with LCD display and LED indicators for BLF, speed dial, and custom function assignments at reception desks and high-volume call environments.
Does the Yealink T46U Have Bluetooth?
The SIP-T46U does not include built-in Bluetooth, but its dual USB 2.0 ports add Bluetooth headset pairing through Yealink's BT41 USB adapter. The dual USB design allows a Bluetooth adapter and a second accessory to operate simultaneously, so the phone can pair wireless headsets while also using a WiFi dongle, USB headset, or USB flash drive for call recording through the second port.
