A Kerio Operator customer reported that a remote extension at a salesman's house was receiving phantom calls from an extension that doesn't exist. Kerio support asked that they turn on both asterisk debug logs and start a packet-sniffer limited to port 5060. This was done, but nothing was seen going to the salesman's phone. They noted:
Proper security on VoIP systems goes beyond the local network if you have remote extensions at user's homes. You probably don't control their router, so thinking about issues like this is important.
