Hello, I continued to see this errors in the logs: <br>
<br>
<font face="Calibri" size="2"><span style="font-size:11.0pt">[2015-12-02
10:05:57] NOTICE[19949]: chan_sip.c:23277 <span class="SpellE">handle_request_invite</span>:
Failed to authenticate device 100<a class="moz-txt-link-rfc2396E" href="mailto:sip:100@xx.xx.xx.xx"><sip:100@xx.xx.xx.xx></a>;tag=10cdeaf7<br>
<br>
how do I guard against this kinds of attacks? Also, to get the
IP address from where this attack come from I use the following
command "tcpdump -lni eth0 -f "udp port 5060" is there an easy
way to get the attacker's IP? <br>
<br>
Thanks, <br>
Motty<br>
