Hi, Need help. I saw this persistent log message when running PJSUA sample program : *14:22:27.749 sip_endpoint.c Message Request msg NOTIFY/cseq=102 (rdata00AD9234) from 153.20.19.191:5060 was dropped/unhandled by any modules* See attached for a more complete log. What is the cause of this log message? Is this a problem. I did mange to receive call from an IP Phone. But the messages looked worrying.
