They are very fast to respond, they give you options that other companies may not offer (such as being able to set up multiple different types of phones). There is no free trial option at this time which I consider unfortunate but understandable given their small size compared with larger vendors like Vonage or even smaller ones such as RingCentral; however it doesn't seem too difficult once we signed our contracts because there was enough flexibility built into them so signing wasn’t something customers were concerned about. We needed an easy way to setup new phone numbers without having to have someone come out everytime - also setting voicemails via email has been extremely helpful!
