I've been tasked to report on traffic flows of Instant Messaging types of communications to include Skype/Vonage use. It certainly is not as simple as the request sounded coming down from mgmt; IM clients port hop, Skype uses ports 80 & 443, etc.
Has anyone looked at this problem and maybe has a template? Is using an URL or domain name an effective filter?
