Developers made it worthless

These guys do not test their product before publishing it. Groundwire used to work but some releases have been buggy / broken features. This last release added “Do Not Disturb” capability - permanently. You can no longer receive calls. Its been over a month and no fix in sight. This publisher is no longer compelling or viable.
