asterisk users - Nov 2018 - Ports that voip hackers seem to be interested in

To any that might be interested, below is a list of ports, preceded by the
frequency.
Personally, I find it interesting that port 5038 is now of such interest to
hackers. This data spans about a day of access attempts. A total of 67
systems (different source IP addresses) participated in this "survey".

These were logged when we dropped their packets.
