The message appears to be correct. There is a problem with the sender, or possibly with a router. According to the SDP, the port should be 65511 or 65513, but was actually 1024.

I couldn’t solve the problem yet. Is there anyone who advises me what to do?

Examine the actual ICE negotiation and the flow of the traffic, and see if it truly is coming from a source that is not in any of the ICE candidates. If that’s the case there’s not really anything you could do, except modify the code I guess to remove the denial of service protection for that scenario.

The router configuration is just port forward to ports 5060 and 5061 and 10000-20000. I understand you reply. do you have any advice to resolve this problem?

Thanks alot
