They can hear me, I can't hear them - incoming calls

Over the past few weeks it is suddenly hit or miss whether I can hear the caller.  I test the settings afterwards and they are fine. 

Also, my phone is ringing, along with my computer, but not giving me a way to answer on the phone, until it finishes one cycle of trying, and continues to ring longer on a 2nd cycle, then the interface on my phone pops up on my phone to answer. 

Why all the sudden bugs?
