Almost perfect... Almost

Believe all the positive reviews - this app is great! I used to use google voice and I had not found a viable app that worked reliably or with ease (and G-voice doesnt allow free outgoing calls!). Sideline has nailed it... But theres one drawback.
Theres something about the way outgoing calls appear to whomever youre calling and I often get a "this number has been disconnected" notification when I try calling. However, if I call again from my real phone number, it will connect just fine. This is problematic if you need to reach clients frequently like I do without them having your real number. So far I have not encountered any issues with clients calling me, though. If there werent any issues making outgoing calls, this would absolutely be a 5 star app. But given this shortcoming, I cant give more than 4.
Texting and everything else work perfectly.
