RFC 3665's Basic Call Flow Examples Revisited

This series of documents illustrates the basic examples provided in RFC 3665, as an aid to SIP implementers, designers, and protocol researchers. RFC3665 is an Internet BCP (Best Current Practices) released in December 2003 and co-authored by: Alan Johnston, Steve Donovan, Robert Sparks, Chris Cunningham and Kevin Summers. SIP messages are reported in strict conformance with this RFC.

Note: PDF documents have been registered with the option "Fit in Window" and should be viewed as such.
