So far, it has been observed every call made to the company doesn’t count as an opportunity for the business while you can miss any call or differentiate at once. Junk or spam calls tend to waste the time and productivity of the agent which leads to inflating the bill expenses. An advanced feature of IVR, the customer is allowed to block all those spam calls by adding them into a blacklist. IVR makes sure blacklisted callers don’t land up on IVR and these callers will always receive a busy tone.

For instance, if a company deals with a particular region then calls can be sorted on the basis of the geographical barring list.

A company can create a whitelist for limited the number of callers to the enterprise. However, all blacklisted calls would be charged on the basic plan for missed calls.
