In 2000 the company moved into IP based videoconferencing using the maturing H.323 standard, making the entire product line IP capable. Since 2000, the company has expanded its product line greatly, by adding enterprise-class MCUs, Gateways, service-provider class MCUs and H.323 Gatekeepers. In 2001 the company also acquired a consultancy company Delante AS which enabled it to focus more on external software integration and bindings, especially the Microsoft platform. In 2004 Ridgeway Systems and Software, a UK based software house specializing in Firewall and NAT traversal, was acquired. The result of this acquisition was the Tandberg Expressway Firewall Traversal technology, which allows any H.323 video endpoint to place calls through any number of firewalls or NAT devices.
