I have the same problem on missing calls on my xv6900. Actually, it happened on my phone after I used it for 3-4 days after I do a soft reset of my phone. The problem is that the ringer dose not ring and it registers the call as missed call. After I soft reset the phone, the problem goes away until 3 or 4 days later.
Seem like a software problem similar to reboot Windows on your computer.
My question is what does the setting of "HKEY_CURRENT_USER\ControlPanel\Phone "Sleep" = 1" mean?
Does it make the phone not sleep anymore?

Thanks for any information
