I would like to point out the offer and answer with no m= lines are technically legal. Here is one example of this:
https://tools.ietf.org/html/rfc4317#section-5.1

In general, SDP session with no m= lines or with all the m= lines refused with port 0 means that the session is active but no media is sent. This is used either to pause playback when communicating with media servers or for session warm up before the actual media is established.
