Reliable incoming calls, horrendous call quality – Acrobits Groundwire Review

Groundwire's PUSH service is the most reliable I've found to receive calls on my iPhone, but the call quality of incoming and outgoing call is absolutely terrible. I have HD voice enabled, and calls are always garbled and have a constant background noise. This isn't a problem on any other softphone app of headphone I've used.
