No, it doesn't. The endpoint has to listen for media at the address and port specified in the SDP it sends, but those can be quite different. (And often is, if any sort of third-party call control is involved (including music-on-hold).) Worse, the media does *not* have to be *sent* from the address/port specified in its SDP. Although some endpoints filter the media packets that they'll accept based on the SDP they receive. The best practice is for an endpoint to send media from the address/port that it used to receive media.
