We used this callback system when I worked at a call center selling products from TV infomercials, although it wasn&#x27;t anywhere near as advanced as the example in this article. The dialing was automated but we had to manually initiate each call, and make sure we were speaking to the right person.<p>I don&#x27;t even know how many times I&#x27;ve said the phrase &quot;We are currently experiencing a high volume of calls&quot;. Hopefully never again.
