In Cisco Unified Contact Center Enterprise Outbound option with SIP Dialer, which two campaign modes require a dialer port to place a call? (Choose two.)

Question

Options

• ADirect Preview dialing mode
• BProgressive dialing mode
• CPredictive dialing mode
• DTransfer to IVR dialing mode
• ECourtesy Callback Dialing mode

• A

• B
  91% (43)
• D
  2% (1)
• E
  2% (1)

Explanation

Progressive (B) and Predictive (C) are the two modes where the SIP Dialer autonomously places outbound calls on behalf of agents, which requires reserving a dialer port (a SIP channel/connection) to manage each call leg. In Progressive mode, the dialer places one call per available agent; in Predictive mode, it dials ahead of agent availability using statistical modeling - both require the dialer to hold that port while the call is in progress.

Why the others are wrong:

• Direct Preview (A): The agent reviews the customer record and manually initiates the call themselves - the dialer is not involved in placing the call, so no dialer port is consumed.
• Transfer to IVR (D): Calls are handed off to IVR resources immediately upon answer; the dialer does not maintain a port holding the call for agent connection.
• Courtesy Callback (E): This mode calls back customers who opted out of queue; the callback is routed through normal inbound call handling, not through a reserved dialer port.

Memory tip: Associate the two P's that need Ports - Progressive and Predictive. Both are fully automated dialing modes where the dialer does the calling, making a port reservation mandatory. Any mode where the agent or IVR drives the call does not need one.
