I need help with Gizmo/GoogleVoice calls on my iPhone with Groundwire 1.1. The Gizmo number is linked to my GoogleVoice account as one of the forwarding numbers. I haven't changed anything from the defaults when adding a Gizmo account, and I don't know anything about codecs to mess with that on my own either.

When I select to call somebody in my Google Voice account online ("Number to call") by using my Gizmo number ("Phone to call with"), Groundwire rings as it should, I pick up and then I hear the ringing of the phone being called. When my friends pick up on their end though, I hear them but they can't hear me at all.

I'm using Groundwire on WiFi only.
