The Yealink SIP-T21P E2 IP Phone’s display is a different colour than the rest of the phone. The phone’s dual colour gives it a one-of-a-kind appearance that will blend in with your decor. Aside from the standard phone, it supports two VoIP accounts, making it suitable for both large and small businesses. HD quality features provide a much more enjoyable user experience. Call waiting, call forwarding, call return, group listening, 3-way conference calls, and other modern call features are available. To make calls, this phone uses the direct IP address rather than the SIP proxy. There are also integrated screenshots, a dial plan, and an XML browser. The phone’s phone book can store up to 1000 entries with phone numbers and names. Because of the presence of an intelligent search method, you can easily search the information, including phone book details and call history. It has a dual colour scheme, and the aesthetics are simply stunning. It has an unknown number call rejection feature as well as an auto-answer feature that can be customised to meet your specific needs. The message waiting for indication assists you, and the voice mail option allows you to leave and receive messages when you are unavailable. It has a 13264 pixel LED display that is medium in size. It has a single colour LED that displays line status information.


  • An intercom, paging, music on hold, call recording, and other modernised features are also available in this user-friendly device.
  • It has two LED line keys, six feature keys, six navigation keys, and two-volume control keys for easy control of the available options.
  • Some of the lights are illuminated for increased visibility.
  • Using the national language selection, you can adapt to your native language.
  • It can also be wall-mounted depending on your needs and preferences.
  • If you require privacy protection, it comes with a phone lock.
