The Yealink T21P has been phased out and is no longer available for purchase. The recommended replacement is the Yealink T31P.
The Yealink SIP-T21P E2 is a step up from the previous edition. The phone offers a backlit LCD display and dual-color LED keys, which the Yealink SIP-T21P does not. The backlit display presents information more effectively and with better clarity. Dual-color LED keys can be used for availability features such as busy lamp fields and immediate line status indication.
Yealink HD Voice technology lends the SIP-T21P E2 phone amazing call quality and voice recognition. Adaptive jitter buffer, echo cancellation and full duplex technology further enhance the phoneâ audio capabilities. Communicate through the phoneâ handset, speakerphone or headset port. The phone supports additional features such as IPv6, OpenVPN and other ultramodern solutions. Power the phone via PoE or the optional AC adapter.
Note: AC adapter not included.
