The predictive dialer adjusts its speed automatically, based on how many phoners are on the system and how many calls are being answered. Sometimes, you will want to adjust the speed of the dialer up or down, especially as a list gets "older" (after a couple of passes). When you start a phoning session, it is important to wait at least 20 minutes before you starting adjusting performance - you want to give the dialer time to assess the dialing conditions and settle into a rhythm.
To assess the speed of the dialer, look at the upper area of the Performance tab. D and %D tell you how many calls the dialer has had to drop. These are calls that were connected to a person on the line, but there were no agents available to take the call, so the dialer had to hang up the call. AW tells you how many seconds your phoners are waiting between calls.
There are no absolute rules on what numbers you should aim for. %D under 5% is important - you don't want to waste the opportunity to talk with people by hanging up on them. Average wait times will depend on a number of factors. Few phoners on the campaign will mean longer wait times. Long conversations also mean longer wait times between calls (because the dialer can't predict when the call will end). Lists that have already been dialed for days may mean longer wait times.
For standard voter lists, using answering machine detection, a ratio of 4:1 is a good starting point. If you are not using answering machine detection, 2:1 is a good starting point.
To adjust the performance, right-click on the campaign name. You will see a drop-down menu - choose the Performance option.
Adjust the speed by changing the Ratio. A higher number (going from 3:1 to 4:1, for example) means that the dialer will use more lines - dial faster. Do not change more than one step at a time. After you have made an adjustment, wait at least 15 minutes before making any further adjustments.
If you have questions about this, feel free to talk with a PCT support person. We will be happy to work with you to make sure that your phoning is as productive as possible.
