If you don't want to have both in the second INVITE, you can try putting both rtpengine_offer calls in branch routes instead. I haven't worked with rtpengine, but with other messages changes like this if you place them in the branch route then they affect only the current branch; after failure the original message will be returned and you may then be able to add RTP/SAVP only.
