Great. Haven't seen this - thank you.

The whole concept is interesting. Suppose the call forks and one UA answers with 484, another with 486 and another with 180 ringing. What are you supposed to do? I think there's a problem with the RFC 3261 here and don't know if it's been clarified.

Now - in the case of Asterisk if we call out to two devices from the dialplan and one responds with 484 and another with 180 ringing - what happens in Asterisk?
