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.
