I'm trying to get the built in VoIP to work with WM6.

Making a LONG story short - I've got it about 99.99% working. Here are the issues:

1. I can barely hear the caller. My guess that this is a codec problem. I'm using Gizmo as my sip. Does anyone know if there is a specific codec I should install and be using?
2. It routes everything to speaker phone - so it's using the external speaker instead of the built in earpiece speaker. This is a well known problem - even all the 3rd party WM6 VoIP clients I tried all had the same issue. Not a huge problem for me as I just use a bluetooth headset anyways, but I'd still kinda like a workaround.

Anyone have any clues?

Thanks!
