Thats normal! The moment you send the 200 OK you must be prepared to receive the media.

Once the final answer is sent, the offer-answer media negotiation is complete. Therefore RTP listening port can be opened just after sending final success response (200 OK) and on the other side RTP data can be sent right after receiving the final success response.

The result is that my device sends an ICMP for the first two received RTP packets. Is this behavior normal or should I not wait for the ACK but open the RTP listen port as soon as I send the 200 OK?
