Understanding VOIP can be a challenge for newcomers, but can it be simple and easier approach?
VOIP is now mostly built with SIP. SIP is textual protocol same as HTTP so if you know HTTP reading SIP messages will be easy. It acts similar and has similar behavior (request/response) but focus is more on Session. With realtime media like audio/video there is always session after which it ends. Creating, Updating, Clossing this Session is something that SIP is designed
To understand and have good debug skills it is important to know how SIP works in different situations. Here I will try to provide some simple documentation to help you BUILDERS.
