481 Call Leg/Transaction Does Not Exist using SipUnit

I've changed from SIPr to SipUnit, and I'm trying to make a basic call. The server has digest authentication. Unfurnately, I keep getting a "481 Call Leg/Transaction Does Not Exist" and I'm sure it is because of a pretty obvious reason, but I can't seem to solve it... I've tried everything. Here is the critical piece from the PBX's logs. Thanks in advance, if someone can explain to me why this is happening!

I'm using code similar to the example TestWithProxyAuthentication.java.

In that flow you attached, registration was not completed. After receiving "407 Proxy Authentication Required", You should send 2nd REGISTER with Proxy-Authorization header.
