This is incorrect. When UA-B sends a 302 Redirect to PBX-2, that means there was never a SIP call established _AT ALL_. Instead the Dial() that was placed by the incoming IAX2 channel out to UA-B is now _redirected_ to the new destination, as if it had called that destination originally.

I don't know what your issue is with RDNIS, but I don't see how that would make this appear to be a 'SIP call', since it is not. It is an incoming IAX2 channel that is now placing a call to the new destination.
