There are no shortcuts, read RFC 3261 thoroughly and mug up
all scenarios of a SIP call, you should know all types of
methods and headers. Usage of Via header and branch
parameter. Why ACK and its significance. Dialog vs
Transaction vs Session. How to modify a dialog? When does
media starts flowing in a SIP call? What will happen if ACK
is lost? How a SIP gateway interacts with SS7 signaling and
give its flow end to end. Hope this helps.
