AG-VIP Overdialer / Predictive Dialer - more time to talk

Basics and aims
TAPI-based overdialer
Integration Predictive Dialer


Basics and aims


The option Workflow includes a TAPI-based Powerdialer. With this you can increase the number of dialing attempts compared to manual dialing by about 40%. The Powerdialer starts a dialing attempt for the agent. If you have a large amount of addresses or a target group with bad availability, it makes sense that an agent starts multiple dialing attempts at the same time. Huge address amounts can be contacted much more efficiently with this tool.

The efficiency advantages of the AG-Overdial server, compared to the dialing processes in the power dial mode, can be simulated previously and free of cost. With the Outbound-Simulator, you see at a glance how much work time you can save and how many more addresses you can contact.

Tapi-based overdialer

Minimum requirements:

  • AG-VIP incl. Option Workflow
  • 3rd-party-TAPI with function "Line Blind Transfer" - see TAPI test tool
  • ideally virtual TAPI lines with no connected device and via which the Overdialer can initiate external calls and, when connected, pass on calls to a free extension line.
  • Sufficient free exchange lines

In contrast to the Powerdialer, the dialing is done via central CTI server. Depending on the set overdial factor, more free lines are being dialed than free agents are available. Background is the assumption that a part of these dial attempts will fail because of busy lines, non-availability or wrong numbers.
+ agents have less waiting time for connected calls
+ higher address throughput More dialing attempts
- Agents sees address record only if the call is already connected
- solely server-based solution
- requires more outgoing lines to make overdial technically possible
- dropped and burned calls, which means several dialing attempts are started for a free agent at the same time As soon as the first call is connected, it is given to a free agent by the overdial server. The other calling attempts are dropped. Should there be a second connected call and no agent is free, the server hangs up (burned call).
Suitable for: B-to-C bulk business
