The service allows hiding the number from which you are calling. Thus,
you ensure yourself a guarantee that your number does not come to a
telemarketing agency and you won’t be troubled by endless calls with offers.
Telephone service companies have created a special communication service without the need to use customer's equipment. It's called a "virtual number". It also has a text type of "virtual SMS center." Thanks to the virtual link you can make calls or send messages while connected to the equipment of the company.
