[asterisk-users] Asterisk 1.8.22

[Mikael Fredin]

It's very likely someone scanning your asterisk for extensions to use for
dialing out through your asterisk. Secure your asterisk and maybe create
extensions that aren't practically possible to find through scanning.

Save logs from your asterisk of whenever an extension is called (if that is
an option) and you will probably see them scanning from 1-1000 or more.

This is very common unfortunately, because too many asterisks are waiting
to be hacked by automated scripts..
