I'm not sure you've provided enough of the trace here. It finds the peer, but 
rejects it with a 401 Unauthorized, which is not uncommon. And I don't see any 
authentication information in the first INVITE. This is why the 401 is sent 
back, as the WWW-Authenticate line contains the realm and nonce which should be 
used by the other end to generate the authentication, and then send another 
INVITE back with authentication.

Since you've only shown the two packets in the trace, it is impossible to tell 
what is going on beyond the 401 response from Asterisk.
