Let me propose an idea: We should consider SUBSCRIBE as a "normally authenticated" request in much the same style as INVITE.
Thus, we would "preemptively" perform the authentication challenge in the Proxy if the request claimed to be from a sipXecs identity that possessed credentials. This challenge would be done regardless of the event package to which the SUBSCRIBE was directed. This would eliminate the directed call pickup problem of XX-7668. I think that it would not cause much extra authentication traffic, as all sipXecs-provided subscription servers require authentication (or should do so). To improve efficiency, it would be helpful if sipXecs subscription clients would "preauthenticate" themselves, that is, provide suitable authentication headers in the initial requests, thus avoiding the additional round-trip for authentication.
