My guess is that the control traffic related to voip might be SIP over UDP. That kind of traffic is soley controlled by the application and the server, if the client is NAT-ed an abundance of SIP control packets might be necessary for keeping the portmapping alive. But these persons who though that a control protocol should be done over UDP, should be the first againt the wall in my book.
