You can install a log watching program that looks out for specific
log entries and can take action. Eg; writing a firewall rule to ban
the ip address of the system trying to make unauthorised calls.<br>
<br>
'swatch' is a good tool for this in linux systems.<br>

look at the 3rd column... This is someone trying to figure out
how to get calls thru your public context with various prefix

<-- that’s the intl destination umber probably a phone in
gaza (definitely in Isreali controlled areas, but I think I
looked up this number or similar number in the past)<br>
<br>
To protect yourself, only allow calls to local extentsions
from the public context... <br>

They're coming in on the 'public' context which'll mean an
unauthenticated call on the external profile. That would be
the context allowing you to receive calls from strangers.
Providing that context doesn't allow them to dial out via
providers that charge you this isn't an issue.<br>
