I just noticed a new drop down at the bottom right corner of the MJ screen on my PC. It has a green 911 circle, shows my address to the right and when you move your cursor over the green circle it says "The 911 service has validated this location successfully".
I am in Canada with no land line. In Canada, we pay 911 service access fees on all our cell phone plans (I think .75/mo.). I'm not sure why everybody is still hung up (sorry, bad pun), on 911 calls with MJ in Canada . If you have a cell, you're good, MJ can be the backup.
