I have this book from a number of years ago and found it quite useful. I like having a resource that isn't Cisco-centric.
SIP: Understanding the Session Initiation Protocol, Fourth edition: Johnston, Alan B.: 9781608078639: Amazon.com: Books<https://www.amazon.com/SIP-Understanding-Session-Initiation-Protocol-dp-1608078639/dp/1608078639/ref=dp_ob_title_bk> From: cisco-voip <[email protected]> On Behalf Of ROZA, Ariel via cisco-voip Sent: June 15, 2021 8:55 AM To: cisco-voip ([email protected]) <[email protected]> Subject: [cisco-voip] Suggestions on book on SIP protocol? People, Can anyone give me a good reference on books that explain the SIP Protocol? I already have a significant working knowledge on SIP. I have set up some trunks On CUCM and CUBE and troubleshooted many more. But I am still lacking on the WHYs of many things. So I am looking, for example, for theoretical explanations of SIP call flows and the variations of headers and options, without being dry as hell as a RFC or Cisco technical documents. Some good book that can be used as reference material. One of the issues I have with Cisco tech notes is that when they do examples-by-debug often they lack explanations or discussion of possibilities. What have you people read and can recommend?
