What is SIP?
The Session Initiation Protocol (SIP) is an IETF-defined signaling protocol widely used for controlling communication sessions such as voice and video calls over Internet Protocol (IP). The protocol can be used for creating, modifying and terminating two-party (unicast) or multiparty (multicast) sessions. Sessions may consist of one or several media streams.
Tulane is leading a new initiative among Internet2 universities to replace our traditional telephone system with a cloud-based SIP (Session Initiation Protocol) system referred to as Internet2 Net+ SIP Service. When complete, users will have much greater control over how they use telephone service. SIP will eventually integrate voice technology with our other systems, allowing procedures like one-click dialing from your computer, integration with Microsoft Lync, and voicemail online. SIP is now in the pilot phase, but once the service goes live, Tulane affiliates will be able to make and receive phone calls using their Tulane phone number from any device – tablet, laptop, desktop or smartphone. Users will have much more flexibility in managing phone calls and voicemail, for example,
As CTO Charlie McMahon said in a recent interview with Information Week “With network upgrades complete, we are rolling out a cloud-based SIP service for our telephony. So we will be able to retire our traditional PBXs. That will allow us to converge our mobile and landline infrastructure, achieving the holy grail of fixed-mobile convergence in the telephony world.“
