I have spend the last 48 hours scratching my head on this one.
Reading all the resources I could find.
I tried the following widcomm versions: 1100,1200,1700,2400,3600,4200
Every conceivable registry setting.
I am happy to say I finally figured it out for my HTC Touch with WM6
Here is the excerpt from the manual that helped me figure it out.
Provide options to set how quickly incoming calls are automatically answered during hands-free operation. Choose options as 3, 4, 6, 8, or 10 seconds). Choose Never to disable this option. However, these settings do not apply when the ring type is Silent.
Red being the important part. I put my phone on normal mode for the ringtone, and what do you know! It now waits for me to accept the call!
Now I must search the rest of the forum for those other users I saw with the same problem. Help it helps
