My Company has used VoiceSpring for going on 3 years and we could not be happier. I have worked in IT for 15+ years and the new hosted phone system along with the $150 a month savings and the support they provide us with is far superior to what we were getting from one of your top 3 phone companies. When calling in or placing a service ticket we are serviced quickly and by someone local and in there office not a call center that is out sourced to some 3rd world country. I have worked with the same techs for the last 3 years and these guys know what they are doing when it comes to phones and networks. They are worth looking at if you are upgrading your old phone system or want a phone system that is very current with the times. Also, as an additional note they also include all future upgrades & warranty for as long as you have their system not yearly maintenance contracts or hidden fees.
