Yealink YEA-SIP-T23G IPv6 Professional Gigabit IP Corded Phone

Yealink SIP-T23G – Affordable Gigabit IP Phone for Small Business

The Yealink YEA-SIP-T23G is a reliable, feature‑packed Gigabit IP corded phone designed for small businesses, call centers, and home offices that need professional voice quality without breaking the budget. With a 3‑line backlit LCD, HD audio, and dual‑port Gigabit Ethernet (with PoE), the T23G delivers fast network speeds and crystal‑clear calls. It supports IPv6, ensuring future‑proof compatibility with modern networks. The phone is easy to provision and use, making it a favorite among IT managers and remote workers alike.

How It Works

The T23G connects to your SIP‑based VoIP system via the built‑in dual Gigabit Ethernet ports – one for the network, one for PC passthrough (saving you a switch port). Power over Ethernet (PoE) allows you to power the phone with a single Ethernet cable, reducing desk clutter. The 3‑line backlit LCD displays caller ID, call status, and menu options clearly. You can manage up to 3 SIP accounts, with dedicated line keys and an intuitive navigation pad. The full‑duplex speakerphone with acoustic echo cancellation ensures natural hands‑free conversations. For private calls, plug a headset into the RJ9 headset port. If you prefer the freedom of a wireless solution, consider pairing this desk phone with a professional wireless headset – explore our selection at FindHeadsets for Bluetooth and DECT models that work seamlessly with Yealink phones.

It features a 3‑line backlit graphical LCD (132×64 pixels), 3 SIP accounts, and 3 physical line keys with LEDs. Audio includes Yealink HD Voice (wideband codec G.722) and a full‑duplex speakerphone with acoustic echo cancellation. The handset is hearing aid compatible (HAC). The phone has two Gigabit Ethernet ports (with 802.3af PoE) and an RJ9 headset port. It is wall‑mountable and comes with a stand for desk placement. The keypad is backlit for low‑light environments.

Why Choose This Product

The T23G offers an unbeatable combination of price, performance, and essential features. Gigabit Ethernet ensures fast data transfer, even when daisy‑chaining your PC through the phone. IPv6 supports future-proofing your investment. The HD audio quality is noticeably better than older office phones, reducing listener fatigue. The 3‑line display and backlit keypad make it easy to use in any lighting. For small businesses, the T23G is easy to provision and manage, with features like remote configuration and automatic firmware updates. It’s also a great upgrade from legacy analog phones or slow 10/100 VoIP phones. The full‑duplex speakerphone is clear enough for small meetings, and the RJ9 headset port lets you use a headset for privacy.
