On-Premises Call Control

An administrator must assist a remote employee in placing a free call to an international destination. The administrator calls the employee and then conferences in the international party. The administrator leaves the call, while the employee and international party continue speaking. Which action prevents this type of toll fraud in Cisco UCM?

  • A Set service parameter ג€Advanced Ad Hoc Conferenceג€ to 2.
  • B Set service parameter ג€Drop Ad Hoc Conferenceג€ to ג€Do not allow outside parties.ג€
  • C Set service parameter ג€Advanced Ad Hoc Conferenceג€ to FALSE.
  • D Set service parameter ג€Drop Ad Hoc Conferenceג€ to ג€When Conference Controller leaves.ג€
Explanation

Cisco Unified CM’s Drop Ad Hoc Conference service parameter prevents toll fraud caused when an internal conference controller disconnects while external parties remain connected. Configuring it as When Conference Controller Leaves terminates the active ad hoc conference when its primary controller hangs up, so the employee and international party cannot continue the call after the administrator exits.
