High security private switchboard 6 Months

These calls are not conventional calls from one phone number to another, these calls are between extensions within the same caller group. Imagine that you subscribe to this service for your group of 5 employees and you want to have the highest level of confidentiality, you will have to subscribe to 5 extensions. Once you have paid for the service for the 5 extensions, you will receive instructions on how to download an iPhone or Android application. In these applications you will indicate the data provided and an extension number. Each of the members of your group will have a different extension and thus the calls will be made point to point without using public telephone numbers. There is no external trunking, so no one can call these extensions and no one can call anyone outside the group from these extensions.
