SIP User Scenarios

The Internet Gate fully supports the SIP protocol, which means that you may use SIP based services and applications all the way from the Internet, through the firewall, and on to your secure inside network.

The Internet Gate keeps track of all connected SIP users. It analyses all passing SIP traffic, handles NAT related issues with private IP addresses and routes incoming as well as outgoing messages to the correct destination/user.

The way the Internet Gate handles SIP traffic makes it useful for more than just a firewall that supports SIP traffic. You can for instance easily set up the Internet Gate to work as a SIP server, allowing inside and/or outside users to register.

If you have a registered domain name you may use the Internet Gate as a SIP server for that domain. With a DNS record pointing to the SIP server, all registered SIP users can be globally reached with the user's SIP address.

Even if you have registered your IP address at Tekea, DynDNS, DNS2Go, or some other dynamic DNS service, you can set up the Internet Gate as SIP server for that domain.

The Internet Gate SIP server also works as an outbound and inbound proxy server when an external SIP service provider hosts the main SIP server. In this case the Internet Gate SIP Server can still be used for local services, such as routing inbound calls, simultaneous ringing of several phones (by parallel forking), 911 emergency call routing and finding the next hop server for outbound calls.
