Hi,
The following is the model definition for the SIP INVOKE method:
The SIP INVOKE method is modeled as a Call Control method that allows one UA to manipulate the state of an INVITE-based dialog on a remote UA.
The following diagram captures the INVITE-based dialog FSM and how the INVOKE actions fit into that FSM. The left part of the diagram covers the UAC actions, while the right part covers the UAS actions.
The actions that applicable to both are in the middle. e.g. Hold/Unhold.
