My sip.conf

This has nothing to do with sip.conf.

It might happen if rtp.conf specified a port range that clashed some other common service, or hacking target, or even if you were pinging a port in that range.

You should get a packet capture and try an work out what service the packets were really intended for, or otherwise whey the incoming packet is damaged.

This diagnostic happens when an incoming RTP packet is malformed.
