Toolpack monitoring sip generator
The Toolpack Monitoring "Sip Generator" is a behavior that can be attached to a call flow, and that will send simulated SIP messages to a destination host, simulating that a SIP calls is being monitored.
The SIP simulator sends SIP messages, but does not expect any reply from the destination. It simulates both sides of the SIP call (simulating a sip "Invite" from one side, then "100-Trying" from the other side, etc.)
It also sends a copy of the monitored legs audio using RTP packets, as indicated in the SDP of the simulated SIP message (Invite, 183-Progress and 200-OK).

SIP simulator call flow
The SIP simulator is behavior (based on CTBCAFCallBehavior) and is thus attached to a call flow. It receives all events from all call legs of the call flow.
It will identify the "main" legs of the attached call flow (one incoming and one outgoing), and watch for call state changes of these legs. Corresponding SIP messages are generated.
