Taking a closer look at SailFin (Part 2) : More Details on SIP features.
By Binod P G on Dec 18, 2008
RFC 3261 defines the basic set of requirements of a SIP implementation. Some parts of the RFC need fine tuning so that it works for all corner cases. I have blogged about how Record Routing proxies can be buggy when the implementation is strictly compliant with RFC 3261. SailFin uses sun deployment descriptor to handle such corner cases.
