    abstract =  {This document defines the SIP INVOKE method, which describes a mechanism by which a UA can invoke a well-defined action on a remote UA. These actions are represented by well-defined URNs that must be registered with IANA. This document also defines a new event package 'invoke', and the Action and Action-Progress request headers.},
