Ok, so you believe the same as before, that a media body establishing a session should probably stop any local tone generation, but that SIP shouldn't specify this interworking behavior. I can live with less specification I just wanted to know if this was an intended change in behavior as opposed to less specifically specified behavior. > > > > I am also curious about whether terminating an existing media stream (e.g., > > 180 with SDP containing m line with 0 port after a 183 with media) should > > restart a local ringback tone. > > Same as above; I dont think its our role to dictate UI. > > -Jonathan R. > > -- > Jonathan D.
