The Yealink T48G is designed to handle demanding integrated communications needs. Yealink claims that the T48G was crafted with a "future-proofed infrastructure investment," jargon essentially meaning that the phone will not fall into obsolescence in the coming years.

The Panasonic KX-TGP600 is the newest iteration of the TGP series of DECT phones from Panasonic.

Polycom also engaged in forward thinking with the release of its UC 4.0 software.
The Grandstream GAC2500 is the first conference phone from the company. It follows in the path of the GXV3275 and 3240 as a touch screen Android device. The smartphone-esque feel makes it sleeker than the conference phones we've become accustomed to, and the inclusion of this sort of interface means that the GAC2500 has already broken new ground, before we even start the review.
The Cortelco C62 marks the company's foray into executive IP phones. Unlike the Cortelco C56, a product that pared down its capabilities as much as possible, the C62 takes a slightly different approach by offering features that are common to most mid range phones (multiple lines, more BLF buttons).
