Works better than any other VOIP app – Acrobits Groundwire Review

I've tried almost all of the other apps available today for VOIP for a hosted FreePBX server and nothing has worked consistently unless I've left the app open in the foreground. Groundwire allows you to do other things on your phone and alerts you to incoming calls with a notification whether it's in the foreground or not. Very solid app and very well done. Worth the money if you need a mobile SIP solution.
