Appendix C State Transition Tables

This appendix contains the state transition tables for all the conversation states. Each table contains the following information:

The intrinsics that can be called from the state.
The state of the local side of the conversation after the intrinsic has executed and a status info value has been returned.
The state of the remote side of the conversation after the intrinsic has executed.

*** means that the state cannot be determined from the local side of the conversation.

Table C-1 “Confirm State” shows the Confirm State transition table.
