Virtual Private Network

The Virtual Private Network (VPN) service allows the CSP’s enterprise subscribers to facilitate communication within the company by utilizing virtual private numbering plans, closed user groups, and advanced call routing functionalities. The multitenant service features instant scaling, allowing the subscriber to immediately increase the number of users without any investments in infrastructure. The service is not location-dependent, enabling the enterprise to cover all of its offices and remote employees.

The service’s integration with the CSP’s billing system allows the provider to offer flexible charging rates to its enterprise subscribers. Different rates can be charged for calls made to other abbreviated numbers within the company, on-net and off-net external calls, and calls made from a specially designated geographical office zone. The service can also split the bill between business and personal calls for each individual user, allowing them to use the same device for multiple purposes. Virtual short numbers can be created and managed at the subscriber’s convenience via a web-based GUI or mobile application.

For additional call control, forwarding, and routing functionalities, VPN can be easily upgraded to a full-featured Virtual PBX. The service can also be integrated with other enterprise services such as Switchboard and Virtual Contact Center.
