SIPSorcery is a service that allows you to manage all of your SIP devices and SIP providers in one handy web based application. Normal VoIP services focus on call termination. call origination, allocating virtual numbers, voicemail etc. Our service is different; it solves the problem of how to juggle multiple SIP services and devices. You can think of it as the conductor in an orchestra where the musicians are your SIP providers and devices.
