Duration: 60 minutes
Cost: FREE
AT&T’s secure VoIP architecture supports advanced applications for business as well as wholesale services that often become the foundation of offers that service providers create for their own customer base. AT&T Labs scientists will present AT&T's scalable VoIP architecture, built for all of AT&T, and demonstrate its application to the unique needs of wholesale customers.
The presentation will begin with a description of the capabilities needed to build the network of the future. The focus will turn to actually implementing these capabilities into the evolving AT&T network using state-of-the-art technology. The discussion will cover AT&T's adoption of IMS and introduce AT&T's Common Architecture for Real-Time Services (CARTS). AT&T's CARTS architecture is based on 3GPP/IMS standards but includes many enhancement to implement current and future real-time services that use IP as the main transport technology. CARTS supports the key apparent trends in the telecommunication industry such as: converged user devices, converged services, multiple access technology, access agonistic services, global mobility with no geographic boundaries, flexible customer-focused network and finally proliferation of services.
The presentation will conclude with a description of the AT&T wholesale offer AT&T Voice Over IP Connect Service or AVOICS, which is CARTS-compliant.
AVOICS is the flagship wholesale voice over Internet protocol (VoIP) offer for U.S. service providers that require IP-based connectivity to AT&T’s global IP network for U.S. domestic originated U.S. and international call termination, utilizing Session Initiation Protocol (SIP) signaling. Based on the design considerations of the CARTS architecture, AVOICS is highly scalable and provides customers with a consolidated method for terminating IP and TDM originated traffic.
