[VOIPSEC] VoIP and Fraud

[Mahesh Thakkar]

Dear All,

I am new to VoIP, but not to communication. I am in telecom for the
last 7 years (GSM) and looking after Revenue Assurance and Fraud. I
would like to know what are the vulnerabilities of VoIP and loop holes
for fraud in practical day to day business and how one can protect or
be prepared to act against VoIP fraud.

Responses are highly appreciated
