[asterisk-users] SIP hacked connection?

[Kyle Kienapfel]

I can only suggest the most obvious cause without knowing how its
configured, sorry.
Take a look at the default context in sip.conf

for me:
[general]
context=default

my "default" context doesn't exist, so if a call comes in from an
unknown user, asterisk complains about not matching whatever number
they are asking for. if i changed it to context=internal which does
have dialing rules, then people would be able to dial out through my
asterisk box.
