  • The GXP 1405 is lightweight and compact. Depending on what you're used to, the hardware quality may leave something to be desired. For example, the base and handset could feel a bit hollow to you if you're accustomed to the thicker plastic found in Polycoms.


  • Whether you're on board with combining Flickr and desk phone or not, the GXV 3175 is an exciting product. The Internet browser application is the best one we've tried on a desk phone to date. GXV 3175 to GXV 3175 video calling worked seamlessly (no surprise), and there is evidence that video will play nice with others as well. The phone offers so many features that I'm sure we left a lot of stones unturned. Is it perfect? No, but that's to be expected when you have a device that's trying to be a jack-of-all-trades.


  • 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.


  • The Grandstream GXP 2020 Enterprise SIP phone is in the company's GXP series of phones, a line that focuses on devices that are "feature rich, auto-provisionable for mass deployment, easy to use and competitively priced". The company specializes in very affordable VoIP equipment and the GXP 2020 is no exception. At around $80, this phone is probably one of the most affordable 'executive class' phones on the market.

    - I appreciate how easy it is to use the phone in general, and how much info it gives in the display.


  • The Grandstream GXP-2000 IP phone is a good choice if you need multiple account handling flexibility and extension phone capabilities, for example, in a small business or home office
