iPod Docks

[DeadRinger]

Have been using the Pure-Fi Anywhere 2 with my iphone 3G for a couple of weeks, everything worked fine until today. Playing Pandora, it interupted the music and rang for incoming calls.  Now when a call comes in, the music keeps playing, no ring. iphone still works fine with Pandora when not docked, calls ring through ok.  What to do?
