Inbound Calls From Korea Not Ringing

[Red Hazard]

The past few days I have seen in Call History calls from a known number in S. Korea posting as one minute but it does not ring. The number is White Listed. Is that causing the problem? BTW, Nomorobo is activated.

There shouldn't be anything different about those calls. If you open a ticket with the examples, we can check the logs to see if anything strange is happening with them. It's possible it's getting mixed up by NoMoRobo or a call filter, but without looking at specific examples though, it's hard to say.
