The Internet Gate fully supports the Session Initiation Protocol (SIP). SIP is used to establish multimedia sessions between users on a network (i.e. the Internet).

By default the Internet Gate is completely SIP transparent. The Internet Gate analyses the passing SIP traffic and dynamically controls the firewall to make multimedia packages pass through.

You can configure how the SIP traffic should be managed by the firewall, set up the Internet Gate to act as a SIP Server for a domain and set up rules which users that should be able to register on the SIP server.

Your Internet Gate can be software upgraded with the SIP Switch Software. This software will enhance the functionality of your Internet Gate and give it PBX-like features for software and hardware SIP clients integrating them with each other, the SIP world and the old telephony network via gateways.
