There are times when you do not want to allow each and every caller to use your toll-free number to contact, instead like to limit it to few paid customers.

For example if a software company, which gives softwares on monthly subscription basis wants to allow only paid customers to contact them on their single nationwide toll-free number to limit the expenditure on toll-free number can activate this feature. With Ziffy white list this can be done in a jiffy.

Ziffy white list allows companies to limit their expenditure on toll-free numbers. This feature saves a lot of money for the companies as only genuine customers will be allowed to call on their toll-free numbers.

If you want to block only a few callers on your IVR or Toll Free number, then you can use BlackList feature.

Kindly note all calls received from unknown numbers i.e. which are not in white list will be rejected and charged @ Rs 0.10 per call.
