Where can I get cheap call forwarding numbers?

Question

Telephony

Hello. Maybe someone knows how Avito and other large portals substitute other customer numbers and redirect to a real number. It is necessary to implement the same thing, but it is extremely expensive to buy numbers for each client, of which there are hundreds with a subscription fee of 300 rubles per month. Is there a cheaper way to acquire a large number of call forwarding numbers?

Answer 1

Dmitry, good afternoon!
It was our company that implemented a case with the substitution of numbers for Avito, Yandex, etc.
We can contact and discuss.

Answer 2

Zadarma - overall great service.
