The SIP Switch is a software that upgrades the Intertex Internet Gate products (Intertex IX66 AirSIP and Intertex SurfinBird IX67) to include PBX-like functionality and also makes it easier for you to manage your telephony. Even without the SIP Switch the Intertex Internet Gate is fully SIP transparent. The SIP Switch extensions (Dial Plan, User Accounts and more) integrate SIP phones with PC clients and ordinary telephones via gateway services.
