Hello, I'm currently researching a project that would enable us to pull the actual signaling (SIP conversation) along with our CDRs The best way I can tell to approach this is to set up a server on a SPAN port which mirrors all my proxy servers' traffic. I was curious if anyone else has ever used this approach; and if so, what tools were being used to filter out and subsequently log the signaling (SIP) traffic. If not, is there a better way to approach the problem? Thanks. -Daniel
