I think that did IT!!!!!!!!!!!!!
just called my phone about 15 times and it rang every single time!
I had only tried the original Sprint radio and with the latest radio 1.11. Now using Tellus 1.04 and my phone seems to be ringing every time now [crossed fingers].
I'm not sure if it was just the radio or a combination of all the other settings with the Tellus radio... but I'll keep calling and will report if my phone misses any calls.
