Really, I want to know the packet of signaling in voip.
For example, after H.323 endpoints have disscovered a local gatekeeper, they must exchange H.225 RAS messages with the gatekeeper. Endpoints first send registration request RRQ messages to gatekeeper on UDP port.. But I don’t know whatthing in “RRQ messages”, the most important that I don’t know the difference between packet of signaling and packet of data.
Could you explain for me ?
