5. After a bridge occurs, we have 2 or 3 channels' CDRs

- 6. Parking has to be accounted for in the code:
- a. Parking will cause ast_bridge_call to return
- either AST_PBX_NO_HANGUP_PEER or AST_PBX_NO_HANGUP_PEER_PARKED;
- in the latter case, peer is (most likely) a bad
- pointer, you can no longer deref it. If it does still
- exist, it is under another's thread control, and
- could be destroyed at any time.
- b. The same applies to AST_PBX_KEEPALIVE, in which
- case, the chan ptr cannot be used, as another thread
- owns it and may have destroyed the channel.
- c. In the former case, you need to check peer to see if it
- still exists before you deref it, and obtain a lock.
- d. In neither case should you do an ast_hangup(peer).
- e. Do not overwrite the result code from ast_bridge_call.
