moto g lollipop error: call not sent. Unable to make outcalls? moto g lollipop upgrade from kitkat 4.4.4, 
I can send SMS, receive call. 

But, whenever I dial a number, try to call someone, I get this message :

Call not sent

What can I do ??
Under "Mobile network settings", I switched "Preferred network type" from 3G to 2G, and rebooted the phone. I was then able to make calls again.
Then I switched back to 3G and rebooted, and it still works.

Odd...
