Yealink SIP-T31P Classic Business IP Phone Description
The Yealink SIP-T31P IP Phone is a popular entry-level IP phone suitable for small businesses, home offices, and general office use. It features a 2.3-inch graphical LCD screen with a 132x64-pixel resolution and backlight for clear visibility. This display is clear and easy to read, even in low-light environments, and is perfect for displaying information such as caller ID, call status, menus, and settings. The SIP-T31P’s intuitive interface and dedicated buttons for common functions make the phone easy to use.
The Yealink SIP-T31P enhances audio quality with HD voice support, and it goes even further by integrating the Opus codec, a highly advanced audio codec known for its ability to deliver clear and natural conversations across various network conditions. Engineered with Smart Noise Filtering Technology, which further improves the audio experience during calls, especially in noisy environments, this IP phone actively filters out unwanted noises like keyboard typing, ambient office sounds, or other distractions, ensuring that the focus remains on the speaker’s voice.
Equipped with unified firmware integration, YDMP (Yealink Device Management Platform), and YMCS (Yealink Management Cloud Service) support, you can easily update firmware across multiple devices at once, ensuring consistency and compatibility with your system as well as enjoy centralized management and monitoring of your Yealink devices. Designed in classic gray color and wall-mountable, the SIP-T31P comes with a multi adjustable angle stand, enhancing ergonomics and usability. You can adjust the stand to your preferred viewing angle for comfortable use whether sitting or standing, making it easier to read the screen and navigate through calls.
SIP Accounts
The Yealink SIP-T31P IP Phone supports 2 SIP accounts, meaning it can handle two separate phone lines. This feature allows you to manage and receive calls on both lines simultaneously. You can use one for personal calls and the other for business or split them based on different services. The SIP-T31P is a good option for environments that require multiple lines on a single device, such as small offices or home offices.
Local Conferencing
Supporting local 5-way conferencing, the Yealink SIP-T31P IP Phone allows up to five participants (including yourself) to join a single conference call. This feature is great for small teams or group discussions, as it enables collaborative communication without needing external conference bridge services. With local conferencing, the SIP-T31P device can host the call internally, so you don’t have to rely on a third-party conference service. You can easily manage your conference call by adding participants directly from the phone interface.
Connectivity, Power
The Yealink SIP-T31P comes with two Ethernet ports (10/100M), which provide flexibility when integrating the phone into your network setup. One of these ports is typically used as a LAN Port for connecting the phone directly to your local network or router and the other, a PC Port used to connect your computer or another device, allowing you to run both devices through the same network cable, simplifying your workspace and reducing the need for additional cables. Additionally, the PoE (Power over Ethernet) support means the SIP-T31P phone can be powered through the same Ethernet cable used for data transmission, eliminating the need for a separate power adapter. This is especially helpful in environments where you want to keep your setup clean and efficient.
Broad Compatibility
Compatible with a wide range of IP PBX systems and platforms, the Yealink SIP-T31P works with popular platforms like Asterisk, 3CX, Broadsoft, Elastix, FreePBX, Kamailio, and Microsoft Teams (with specific configuration). This broad compatibility ensures the SIP-T31P can seamlessly integrate into many existing VoIP setups, making it a versatile choice for businesses with varying infrastructure needs. Plus, this phone supports EHS (Electronic Hook Switch) wireless headsets, which allows for hands-free communication. You can pair the SIP-T31P with compatible wireless headsets from brands like Yealink, Plantronics, and Jabra, providing more freedom and flexibility during calls.
