> Using the Dial application, when the outgoing call leg receives a 200 from the callee answering the call, and then immediately after receives a re-INVITE from the callee updating a media stream direction, Asterisk does not correctly update the media stream of the first call leg (to the caller). Asterisk does send multiple re-INVITES to the first call leg but the last one does not contain the correct stream directions from the re-INVITE.
> When sending the re-INVITE with some delay (e.g. 500ms), Asterisk correctly updates the stream direction of the first call leg (see attached traces).
