Are there any advantages of outbound calling over inbound?
There are two advantages. One is that call centers doing outbound calling are only open those hours during which they can call; that is, they are not open 27×7, but perhaps 9am to 9pm, Monday through Friday. (Though some calling does lend itself to weekends.) The other advantage is that you only schedule your staff to work when there is work to do. This way your labor costs track with your revenue.
