For a case in which a proxy forks an INVITE to two locations (A and B), receives a 407 from one location (A) but waits to see if its the best response, then receives a CANCEL from the caller, which results in sending a CANCEL to other location (B), which eventually results in the proxy receiving a 487 from B. Which response does the proxy return to the caller?
It seems the 487 is the response expected by the caller, but RFC 3261 states that some 4xx responses, such as 407, should be given precedence over others. I could not find a clear answer for this anywhere. Any help would be greatly appreciated.
