What should be my main concern when making a VoIP conference call? Should a business worry about confident data being tapped or a third party listening to the conversations?
I have had this question before, and in my opinion, a business has a far greater risk from the cell phones that their employees carry around and use in public areas. I have heard conversations from competitors in airports, on airplanes and conferences. But back to your question, if the network is set up properly, you should be fine. I feel that you would more likely face an attack to web servers or have laptops stolen and used than to have your VoIP compromised. There are several ways to secure the voice links, just as in data, for instance VPNs.
