I can't imagine what. The selection of active/passive is pretty 
straightforward and doesn't depend on much of anything. The 
offer/answer/delete commands as reproduced in full in the log are all 
the input that rtpengine gets, and with the same input it should always 
produce the same result.

The only thing to consider is that in your pasted log, the "offer" 
command is truncated in the SDP and so some of the flags are missing. I 
don't think they would make a lot of difference though, and I tried a 
few different variations and still couldn't reproduce it.
