Call Scenarios and Applications
Issue  7 March 1998
A-83
In call sequence 3, a recording device is added to the call using Single-Step 
Conference. This could be done (for example) when an agent signals the 
application to record this call.
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.
