Calling Card System

Built-in Virtual Office

More than just a unified account, this service provides a virtual PBX where several ordinary numbers combine to make up a virtual office. Every virtual office has its own IVR, voice mail and fax service. You can freely configure the list of services available - number shortening, call forwarding, conference calling and many more.

The Virtual Office feature makes PROTEI Calling Card truly unique on the telecommunications market.

Tariff flexibility

Call costs can be calculated depending on the calling number, recipient number, time of day, type of card and geographical location of the subscriber - an important plus when dealing with mobile subscribers.

Full range of card types

Allows debit, credit and no-limit cards.

Billing system

Built-in billing system with RADIUS support. Can equally be integrated into your own billing system.

Operating and Maintenance Center

Powerful maintenance and statistics system.

Remote workstations

System has Web access with full support for remote dealers.

Private and corporate users

Using Call Back, where incoming calls are free the subscriber pays only for the conversation, not for connection to the Call Center.
