  • There is already an open issue for this[1], but noone has worked on it as of yet.

    I can’t say for certainty, but this is likely because of the way codec and stream negotiation in Asterisk works. Each leg is independent (negotiated between Asterisk and an endpoint), and the result of an outgoing leg (be it from a 200 OK or 183 Session Progress) is not forwarded to the calling side. There is continued work being done to improve this so in the future it could become smarter, but it is not yet there.
