[SIPForum-discussion] Update and re-INVITE

[asif hykadi mushtaq]

Its mentioned in RFC that 
- "re-INVITE has an impact on the state of the dialog, in addition to the session."
- "Update can be sent by a UA within a dialog (early or confirmed) to update session
parameters without impacting the dialog state itself"


Wanted to understand whats mean by state of dialog and state of session.


Regards,
Asif
