sounds like you have port 5060 or your sip extension port open to all and are being attacked.

are they sip or ip phones

yes, SIP extension .

already change port 15060/15X6X but still call from 100/101/XXXX. any solution?

Have you setup the proxy port to something out of the way like 1xx or 7xx on the system media gateway and have your firewall block the internal port for the sip server, use the fire wall to do port forward from that port to the sip server internal address.

keep away from the 15xxx ports on the proxy
