Usually those kind of problems come if people are not using an outbound proxy. Other problems are when phones place calls from received call lists where the contact is not clear. But it should be possible to locate the problem looking at the INVITE with the Request-URI.
In your setting the line 1 looks a little bit suspicious because the domain name is a IP address. In multiple-domain environments it would be a little bit strange to have a alias name that is the IP address.
Maybe you should try to temporarily remove the alias name "localhost" to really point out where the domain does not match in your setup.
Where you able to fix this problem? I'm having the same problem and I'm going nuts trying to fix it.
