The IP Phones you choose will be important, because they are what you and others at your company will interact with daily.  And if you’re on the phone all day, ease of use, sound quality and durability are going to be important aspects of any phone you buy.  There is a variety of new IP SIP based phones on the market, many of which are probably pretty good, but a few may be less so.  That is why we have recommend and supply well known tried and true established IP phone manufacturers, each with a set of models that bridge the gap between the lower cost models and the full featured high end model.  Our list is not without future consideration of adding other models and manufacturers, but should suffice as a good place to match the needs and price points of 90% of IP phone buyers.  Match your IP business phone system with the right IP phone.
