Call Scenarios and Applications
In call sequence 3, a recording device is added to the call using
NOTE:
State or national laws may require you to inform the parties on a call before recording the call.
The recording device is treated as a party on the call. A single party dropping will still leave two parties on the call, so the call will not drop automatically at that point. The application must drop the recording device when it is appropriate to do so. In this example, the application drops the device when it sees station A drop from the call.
