Depends on the config and what type of message the caller managed to
make asterisk create... You could (and probably should) put asterisk on
a private routable network (i.e. NATed behind a firewall). The best
would be to put ser and asterisk on the same network and only allow
outside world to contact ser and let ser contact asterisk using the
private address of asterisk. Alternatively you could use tcp to
asterisk and stop udp traffic.
Why the caller wouldn't receive audio, I don't understand...

Hi guys. Say you have this setup, with an account for
the caller on both
Asterisk and SER:
Caller -> SER -> Asterisk -> VoIP Provider -> Callee
If the caller were to spoof SER's IP address and place a call directly to
Asterisk (thus circumventing SER), what would happen?
If the call was in fact setup, obviously the caller would not receive any
audio from the callee. However, would the call be setup? When Asterisk
responds to the caller's request and sends SIP packets back (to SER),
would SER say "I don't know anything about this call! Asterisk, kill this
call please."?
Thanks for your input!
