I posted the below prior to seeing this thread was ongoing:

Up until yesterday and today I've been very happy with my MJ. Yesterday, however, it started a trick that I'm not fond of. I can call out with no problems, but incoming calls result in dead air. I find out when I call them back that they can hear me but I can't hear them. I've called my number using my cell phone and my wife can both hear me and talk with me perfectly. Of course that's while we are both in the house.

I ran a VoiP test for those of you who are a technically inclined (I'm not) and got the following results.

download speed - 2.88 mbps
upload speed - 716 Kbps
quality of service - 99%
jitter - 0.1 ms
packet loss - 0.0%
MOS score 4.0

None of that means anything to me although the narrative that accompanies the scores says that I should have no problem sending and receiving high quality voice and that has been the case up to this point.

Anyone have any ideas? Please keep it simple as I'm not overly conversant in MJ!
