Unless you enjoy spending money out the wazoo for VoIP hardware, the latest Grandstream phones, four additions to their GXP series aimed at fulfilling desktop phone needs for SMBs, should interest you, according to a recent review from OnSip.com:

“Today we’re going to be taking a quick look at the GXP 2100, a phone that currently sits in the middle of the pack. Introduced back in October of last year at ITEXPO (News - Alert) West, the GXP 2100 is Grandstream’s 4-line desktop phone.”

It supports HD audio on the handset, and features a back-lit 180 x 90 LCD “that’s small but gets the job done,” the reviewer notes, adding that “if you’ve ever used an older Grandstream phone from their GXP series, then you’ll be familiar with the key setup on the 2100.”

Other points from the review:

Voice quality
Calls negotiated using the G.722 wideband codec sound great on the Grandstream GXP 2100. It probably isn’t quite the best example of high definition audio we’ve ever heard in our long history of phone testing, but it is still very impressive considering the price of the hardware. If you’re looking for a way to introduce high definition audio to your team, the GXP 2100 is an inexpensive way to do it. Note that you will not get the benefit of high definition audio when calling a landline, mobile phone number, or another VoIP user who doesn't have hardware that supports G.722.

Ease of use
GXP 2100 doesn’t stray too far from the other phones in the GXP line. With 4 line keys and 7 configurable multi-purpose keys (BLF/speed dial), the phone can handle up to 11 call appearances, more than enough for your average user. Users can configure their 7 multi-purpose keys in the Grandstream device configuration web portal.

Summary
We were impressed with this phone, which is no surprise considering that we also liked the GXP 2020 when we reviewed it last year. The GXP 2100 does just about everything comparable VoIP phones from competing manufacturers can do at a fraction of the price.
