We've been using Dash from VirtualPBX for about 4 months now. It's great. It has all the features we wanted. We have 6 lines. We use YeaLink handsets with the service and we have great call quality. We switched to the Dash offering because it allows for simultaneous ring. Now any available rep can pick up an incoming call. I worked with support when setting up the Dash service and they were very friendly and knowledgeable.
