SIP Configuration

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.

The SIP Switch

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.

Specific users that you want to be able to register on the Internet Gate you add in the table:

SIP User Name If Match full SIP URI for incoming calls is selected under General SIP server settings , you should enter the full SIP User Name (e.g. peter@company.com) in this column, otherwise just enter the SIP User Name e.g. “peter of peter@…). This is also the user name you enter when logging into the personal page through User Log In at the first page of the user web interface.
Authentication User ID Enter the User ID used for authentication of SIP requests. Authentication for registering at this SIP Server can be turned on in the General SIP Server Setting and authentication can also be forced in the Dial Plan.
