    Connected to my Shoretel IPBX quickly. Call quality was good. But even with it disconnected, it was killing my battery.

    Unless you're a telecom engineer or incredibly cheap or incredibly poor, there is no reason to use this complicated mess of a program and protocol. Stay away from SIP and you'll live a longer, happier life.
