Yealink SIP-T28P Review
Yealink, a Chinese manufacturer of IP phones, is starting to make inroads in the U.S. market with its line of VoIP phones. Several months ago Yealink sent me a Yealink SIP-T28P IP phone to review. The SIP-T28P is a six-line phone sporting a large 320x160 LCD screen and has full HD voice support (wideband codec, wideband handset, wideband speakerphone). The SIP-T28P was one of the first IP phones to support the G.722 wideband codec that is now all the rage in the VoIP market.My first impression of the SIP-T28P was that I liked the large LCD and the sleek ergonomic design, which had large, easy to press buttons and a useful four-way arrow navigation keypad.
