This situation is not a problem, and therefore does not need a solution: A request sent to the AOR will be parallel forked to both Contact 1 and Contact 2. Clearly, the request to Contact 1 will receive no response. But the request to Contact 2 will reach the UA and receive the proper responses. The request to Contact 1 will be abandoned or terminated either by timeout or when the UA sends a final response. Most importantly, this is an example that parallel forking is an *intrinsic* part of the SIP architecture, and SIP systems that do not perform it well will never work completely correctly.
