Why isn't my Lumia 1520 ringing?

Lumia 1520 not ringing

A call will be made to me, but it won't ring; then I will be notified that I have a missed call. A minute or two later, another call will come in, from the same caller trying again, and it will ring through just fine

Do a soft reset, just to see if it helps matters. Come back and tell us if it worked or not, and we'll go from there.
Have a lovely night.
