Featuring a large 7″ digital TFT-LCD with 800×480 pixels resolution, the VP-2009 is pretty slick looking and supports HD voice (G.722) and popular HD codec (H.263 & H.264). Installing the VP-2009 was a breeze. I didn’t even have to reboot the phone. The call quality was excellent. And I also tweaked the picture quality and frame rate slider. There was no lag, excellent resolution, and fast frame rate for the video transmitted by the VP-2009.
In any case, let me just say the VP-2009 has one of the loudest speakerphones I’ve ever tested. I couldn’t believe how loud it was with absolutely no distortion. Echo cancellation is critical when using speakerphone at a high volume and I found the VP-2009 to perform beautifully. No complaints. Adjusting volume is done via the touch screen as well as the physical left and right arrow buttons
Conclusion
I was very impressed with the Yealink VP-2009. The video quality was excellent, the touch screen was very responsive, the speakerphone quality and volume was very good, and this phone just looks good sitting on your desk. I’ve said it before, but I will reiterate that Yealink is making in-roads into the U.S. IP phone market. This is now the second Yealink IP phone I’ve tested and I’ve been very impressed both times. Yealink offers a plethora of features at a very affordable price. I fully expect Yealink to improve market awareness and market share if they keep producing high-quality and feature-rich products like the Yealink VP-2009 video phone. I predict Yealink will have at least 10% U.S. market share in new IP phones purchased by the end of 2011.
