The Yealink SIP-T48S is a full-featured Gigabit IP desktop phone engineered for executives and busy professionals who demand a premium communication experience. Centered around a vivid 7-inch 800x480-pixel backlit color touch screen, the SIP-T48S delivers intuitive navigation between applications, directories, and call screens. Yealink Optima HD Voice technology — incorporating wideband codecs including G.722, AMR-WB, and Opus — ensures lifelike, crystal-clear audio on every call. The phone supports up to 16 SIP accounts simultaneously and features dual-port Gigabit Ethernet for high-speed network connectivity. Power over Ethernet (IEEE 802.3af) eliminates the need for a separate power supply. A USB 2.0 port enables optional Bluetooth (via BT40/BT41 dongle), Wi-Fi (via WF40/WF50 dongle), USB call recording, and USB headset connectivity. The SIP-T48S supports up to 6 EXP50 expansion modules for up to 240 additional DSS keys, making it ideal for receptionists and power users. Built-in security features include TLS/SRTP encryption, OpenVPN, and IEEE 802.1X. Compatible with major IP PBX platforms including 3CX, BroadSoft BroadWorks, and most SIP-based systems. Power supply is not included.
- 7-Inch HD Touch Screen with Optima Voice: The SIP-T48S features a 7-inch 800x480-pixel backlit color touch screen that makes navigating calls, directories, and applications fast and intuitive. Yealink Optima HD Voice with wideband codec support (G.722, AMR-WB, Opus) and full-duplex hands-free speakerphone with AEC delivers crystal-clear audio quality on every call.
- 16 SIP Accounts and Gigabit Ethernet: Supports up to 16 simultaneous VoIP SIP accounts for maximum call handling flexibility in busy environments. Dual-port Gigabit Ethernet enables rapid call routing and allows the phone to share network connectivity with a connected PC without requiring a separate port. IEEE 802.3af Power over Ethernet (PoE, Class 3) is supported — no separate power adapter required.
- USB 2.0 for Bluetooth, Wi-Fi, and Recording: The built-in USB 2.0 port enables flexible expansion: add Bluetooth via the BT40/BT41 USB dongle for wireless headset connectivity and contact sync, or add Wi-Fi via the WF40/WF50 dongle to connect wirelessly. The USB port also supports USB call recording directly to a flash drive and wired USB headset use via the Yealink UH36.
- Up to 6 Expansion Modules and 29 DSS Keys: The SIP-T48S supports up to 6 EXP50 expansion modules via the RJ12 EXT port, adding up to 240 additional programmable DSS keys with LCD and LED indicators — ideal for attendant console or reception deployments. The phone itself provides 29 one-touch DSS keys plus 7 feature keys (message, headset, hold, mute, transfer, redial, speakerphone) and 6 navigation keys.
- Enterprise Security and Easy Provisioning: Security features include TLS/SRTP voice encryption, OpenVPN, IEEE 802.1X, AES configuration file encryption, and HTTPS certificate management. Zero-touch mass deployment is supported via Yealink's Redirection and Provisioning Service (RPS). Compatible with 3CX, BroadSoft BroadWorks, Cisco UCM, and most SIP-based PBX platforms.
