Seeing an issue with early media that arrives before the 180 or 183 with SDP. When the media arrives prior, it is being buffered and then flooded out once the 180 or 183 arrives. This causes the delta on the packets to be around 0 instead of ~20ms. Once the buffer is cleared the call is fine for the remainder of the call. Here is a short sample of the packet timing from rtpproxy to the client side.
