A primer lesson in SIP


Tags :


There has been lots of talk recently around SIP and getting connected to each other via Sametime.  What the heck is SIP?  To most of us it is just magic after many hours of stirring the kettle of SSL and ports.  Would it trouble you to know they designed the RFC's for SIP around the SMTP, HTTP and SDP protocol RFCs ?  It goes on to scavenge parts of others before finally deciding it can run on multiple protocols like TCP and UDP.

NOTE: However, Sametime SIP does not support UDP, only TCP.  Sametime also does not allow you to add groups from a SIP community to your buddylist.  You can create a group and then add SIP users individually to that group.  You cannot just grab a group like you are able to from the Sametime directory.  The SIP task in Sametime is also one of the last tasks to start up.

Whew!  Who knew it could be so much fun.
