It happened that rtpengine with multiple rtp workers sometimes receives 
RTP packets ordered sequentially but forwards them a bit reordered 
introducing out-of-order frames. With one rtp worker everything works 
fine. The idea was to start a couple of single threaded rtpengines and 
loadbalance from opensips. But it looks like not with the current 
opensips/rtpengine module.
