Like it.
This is a great simple app. I use it through my Voip provider voip.ms, without any issues. The developer is quick to respond to support questions. When they sort out having this reconnect from sleep this will be perfect.
I do like the ideas shared below to have this sit in the system tray as a drop down perhaps make it a premium option I would be willing to pay for that
