Anyone using Weave VoIP? Specifically with Revolution EHR? I got a cold call from them and sat through their demo. Seems like it has some very cool features and attractive pricing. We've been considering making the switch to VoIP for a while, and if this works as advertised it could save us some $$ and headaches. I found some reviews on Google and many were good but some were alarmingly negative, so I'm hoping someone here has some real world experience with them.
