The Intertex broadband router are the first in the world to allow SIP communication. It has a very general and well-proven SIP support by integrating a SIP proxy and a SIP registrar, dynamically controlling the NAT and firewall. Conventional fi rewalls and NAT routers cannot even be configured to handle SIP between a LAN and the Internet! Microsoft Windows Messenger as well as the Live Communications Server are based on SIP and are expected to rapidly bring Presence, Instant Messaging, Voice, Video and Data Collaboration to the enterprise and everyone's desktop.

The SIP Switch streamlines the usage of email-like SIP addresses used by soft SIP clients and numbers used by SIP phones. It routes common phone calls to PSTN gateways, does ENUM look up, can forward calls and can fork incoming calls to several phones or to voice mail. You can also get your own local numbers, dial 0 (or 9) to reach the outside world and other functions familiar in the old telephony world. In addition you get a set of new features only available in the IP world.
