</span>sip.conf configuration<br>
In the [general] section, define:<br>
<br>
<br>
[general]<br>
...<br>
allowguest=no<br>
alwaysauthreject=yes<br>
...<br>
<br>
<br>
The "allowguest" line disables anonymous SIP calls to your PBX. Some SIP<br>
providers connect as a guest user, however, so this may be inappropriate<br>
for your situation. Also, if you want to accept anonymous SIP calls,<br>
this line would block them, so you wouldn't want that. But it is listed<br>
here because it is the safest configuration.<br>
<br>
The "alwaysauthreject" line is important. This causes a hacker to get<br>
the same response from your PBX when they try to guess passwords whether<br>
or not they guessed a valid username. This also has the side-effect of<br>
making poorly written scanning scripts (the vast majority of hacker<br>
scripts seem to be poorly written) take less resources on your Asterisk<br>
box, as even if they scan a valid username, they'll think it doesn't<br>
exist.<br>
