Yes, it is correct behavior. It is the *required* behavior for proxies. See RFC 3261 section 16.7 item 5. > Is this right behavior of proxy or it should forward only the ringing > response in which call leg it has been answered ? Consider the case when both legs have returned a 180 but neither leg has been answered. At that point, the proxy cannot guess which leg will be answered, so it cannot use that information to determine which 180 to forward.
