I am seeing hundreds of suspicious messages in the Asterisk Log File full on a server. It is Asterisk 2.9 and is very old right now. I am working on updating our installation and am very new at this.
/var/log/asterisk/ tail -f full
Such as:

They do not appear to be getting through and hacking our trunksWe were going to block these IP Ranges in our firewall. Does anyone know any negative affects this may have?

Thanks in advance if you can help.
