Test: Using ChanSpy in Asterisk
We need to find a way for one super-user to be able to listen to conferences A and B at the same time but the conferences should not hear each other. (Most likely, can't use ConfBridge)

Cureent solution:
1. As soon as someone goes into Conference A, we have a dummy user connecting to the same conference. (The dummy user/channel is necessary in order to deal with multiple users coming and leaving the conference).
2. Using Chanspy, we listen to and clone the dummy user's channel.
3. We connect cloned channel to Conference C.
4. Repeat steps 1-3 for Conference B.

Questions:
• Do you have any issues with the current setup?
• Do you have a better solution?
• Approximately how many lines of code will the solution take?
• How many hours will this project take?
