Dialing Modes

When you configure your Outbound campaign, you'll need to choose a dialing mode that best suits your campaign. The dialer you choose will depend on the type of campaign, the number of agents assigned to the campaign, and legal requirements. The article and video below provide an overview of each dialing mode.

Automatic Dialing

When you use an automatic dialer, the dialer automatically dials phone numbers and then bridges the answered calls to agents. You have two automatic dialer options to choose from: Predictive and Progressive.


Predictive is the fastest among all the dialing modes because the automatic dialer uses an algorithm to predict agent activity and call flow so that it can safely dial multiple phone numbers for each available agent.

Because of this constant rate of dialing and connecting, agent idle time is reduced, and the dialer can run through the contact list much quicker than it could in any other mode.

To minimize call abandonment, use Predictive only in campaigns with at least 15 agents.


In Progressive mode, the dialer places only one call for every one available agent. For example, if six agents are available, the system dials six phone numbers.

This guarantees that there’s an available agent for every contact who picks up the phone, so there’s no risk of exceeding the 3% allowable call abandonment rate set out by federal regulations.

Use Progressive if you have fewer than 15 agents assigned to a campaign.

Switching Modes: ASM and Transfer

When a campaign using an automatic dialer runs in Active Switching Matrix (ASM) mode, the system does two things before it dials out: it looks at the routing parameters so that it knows how to route the call when it detects a voice on the line, and it reserves an agent up front. By doing this work up front, it can safely bridge the call to an agent within two seconds after detecting a voice on the line, as required by federal regulations.

When a campaign runs in Transfer mode, the system waits until it has a contact on the line before it checks the routing parameters and looks for an agent. Because this process will always take longer than two seconds, it’s not recommended in sales or telemarketing campaigns that are bound by federal regulations.


To enable Progressive or Predictive dialing:

  1. On the Outbound tab, go to Pattern Options and select Dialer Pass
  2. Select Pacing Options
  3. Check the box next to Enable Predictive Pacing to enable Predictive dialing or leave it unchecked to enable Progressive dialing
  4. Check the box next to Enable Fast Bridging to run the campaign in ASM mode. If you don't check the box next to Enable Fast Bridging, the campaign will run in Transfer mode.

Manual Dialing

In manual dialing, agents dial customers or contacts manually.


Preview dialing is a manual dialing mode, where an agent requests one or several records from the system, previews each record, and dials the contacts manually.


To enable Preview dialing:

  1. Go to the Outbound tab
  2. In Pattern Options select Preview pass
If you select the Preview pass, the system will not honor any Pacing Options.

Outbound IVR

Outbound IVR dialing enables you to play personalized and interactive automated messages to your contacts. All processing of these outbound calls is handled by Designer.

There are two Outbound IVR dialing modes: Power GVP and Predictive GVP.

Use Account Manager to enable the dialing mode and use Designer to set the routing parameters.

For both Outbound IVR dialing modes, you must create an Agent Group in Platform Administrator and select that Agent Group when creating the sub-campaign in Account Manager.

Power GVP

With Power GVP, messages can be personalized for each contact and they can be interactive (For example, Press 1 to take the survey). Agents are not involved in these campaigns, so contacts are never given the option to speak to one. When the message ends or when the contact completes an interaction, the call ends.

Power GVP uses a Fixed pacing model, which enables you to specify a number of contact attempts per minute.


To enable Power GVP:

  1. On the Outbound tab, go to Pattern Options and select Voice Pass
  2. In Pacing Options, specify the following:
  • Pass Name
  • Pacing Model: Fixed
  • Requested Attempts per Min: Specify a number
  • Priority: Mandatory

Predictive GVP

Predictive GVP is similar to Power GVP, but with this mode, a contact is given the option to speak to an agent (For example, Press 1 to speak to an agent).

Predictive GVP can run in either ASM mode or Transfer mode. and you can select pacing options based on either the Target Abandon Rate or the Average Distribution Duration.


To enable Predictive GVP based on Target Abandon Rate, specify the following in Pacing Options:

  • Pass Name:
  • Pacing Model: Predictive
  • Check Abandon Rate Pacing
  • Target Abandon Rate: 3%
  • Priority: Medium

To enable Predictive GVP based on Average Distribution Duration, specify the following in Pacing Options:

  • Pass Name:
  • Pacing Model: Predictive
  • Click Average Distribution Duration
  • Average Distribution Duration (secs): 30 (for example)
  • Priority: Medium
