/mcpCall Is Redirected to a Hunt List of Chaperones and Chaperone Enables Call Recording and Conferences in the Called Party Configuration Phone A, C1, D are in cluster devices. B matches the translation pattern BXXX where External Call Control is enabled. Application sends a lineMakeCall at A to call B. CEPM determines this calls need to have a chaperone’s supervise. CEPM returns the permit decision with the obligation <divert>, destination HuntPilot C, which is a hunt pilot of chaperones, and a reason string “chaperone”. CUCM redirects the call to the hunt pilot C, and the chaperone member C1 answers the call. After talking to A briefly and discovered that A intended to talk to D, the chaperone C1 starts to establish a conference to D. C1 presses the conference softkey and dials D. CUCM queries CEPM for the call, with calling user C1 with DN C1, and called user D with DN D. CEPM returns the response with permit decision with <continue> call routing directive, since the policy server detects that the caller is the chaperone. CUCM rings D’s phone and D answers the call. C1 presses the conference softkey again, and the conference is established. The chaperone C1 presses the “record” softkey. This triggers the call recording being setup from C1’s IP phone to the recorder. When the call recording is eablished successfully, the recording warning tone is playing to the C1’s phone. The recording warning tone is enabled by setting service parameter Play Recording Notification Tone To Observed Target to True. A and D starts to talk under the supervision of the chaperone.
