Help S4 calling problems

[StaraZagora]

Hi all! I'm a proud owner of a Samsung Galaxy S4 and a few days ago the OS has been updated to the last one 5.0.1. (mostly known as Lollipop). But... unfortunately I've got a problem when receiving a call from certain numbers... Any ideas how to fix that?
Thanks a lot!

You've not actually said what the problem is, which is a bit of a problem for diagnosing it and helping you.

Is there anything special/different about these numbers as opposed to those that do work?
