Hi list,
i noticed from the cli my asterisk box is accepting unauthenticated calls
how can i prevent this?
CLI:
-- Accepting UNAUTHENTICATED call from 192.168.0.2:
> requested format = gsm,
> requested prefs = (),
> actual format = ulaw,
> host prefs = (g729|ulaw|alaw),
> priority = mine

Isn't that an internal ip address?
Cheers,
Dean

The way that I've done it is to set the context= line under [general] in sip.conf to a context that just gives the congestion command and hangs up the call, something like this: exten => s,1,Answer exten => s,n,Wait(2) exten => s,n,Congestion exten => s,n,Hangup I suppose you could really just use Hangup instead, but this seems to work for me.

Actualy to have fun.. make it a playback(dialtone),300 ;) that will make your little hacker think they have a dialtone then Record the number dialed and put that in a db for further investigation.. Actualy could also be a user that has no clue on how to configure the system.
