I assume that you mean that the 100, 183, 180, and 200 are responses to the initial INVITE. As always, the response to a request is routed using the Via headers as they appear in the request when it reaches the UAS. > 2/ MGCF has to send a BYE; Will it use Record-route here? Once the dialog is established, all requests sent by a UA within the dialog (such as BYE) will be routed using the Record-Route headers as the UA received it in the request or response which established the dialog.
