This says you were running DTLS-SRTP on both sides of the call. Probably 
not what you wanted, since the first side is only reporting errors and 
no valid audio received. Check your signalling to rtpengine, probably 
you're using the same flags for both offers and answers, or possibly no 
flags at all. Enable debug logging in rtpengine to see exactly what's 
coming through.

Cheers
