Integrating the Next Generation Technology at the Core There are four telecommunications protocols that dominate the business telephone system industry: SIP, H.323, VoIP and TDM. Unfortunately, heretofore no telecommunications manufacturer was able to provide a single, turn key solution to integrate these standards into a single autonomous unit. In 2005, Iwatsu Voice Networks released the Enterprise-CS, a Multimedia Protocol Gateway using QuadFusionTM Technology. QuadFusionTM was designed to capitalize on the benefits of all four voice technologies. If desired, SIP, H.323, VoIP and TDM can run exclusively on the Enterprise-CS or they can be mixed and matched as dictated by the application. And because each call control application runs at the core, each protocol runs as fast as the next. Background A Telecommunications When designing the application software for the Enterprise-CS, developers used an open architecture model that leverages current and future call control vehicles. The hand picked design team spanned three continents and had the combined goal of designing a single system that is not only flexible, but also capable of becoming the market segment leader. After many months of research and design, QuadFusionTM Technology was born. At the core, the Enterprise-CS is a Multimedia Protocol Gateway (MPG) that was designed around the QuadFusionTM Technology. This is a key factor because it allows customers to leverage the best solution at a given time; yet Enterprise-CS MPG is flexible enough to upgrade to a completely different technology at a later time. Simply put, Enterprise-CS MPG synergizes four disparate telecommunications standards: Session Initiated Protocol (SIP), H.323, Voice over Internet Protocol (VoIP) and Time Division Multiplexing (TDM). Each standard has its own strengths and weaknesses. The Enterprise-CS MPG with QuadFusionTM Technology embraces each standard’s strength. What emerges is an entirely new paradigm of flexible voice communications. SIP Session Initiated Protocol (SIP) is a stateless, client-server protocol used to establish communication rules on a case-by-case basis for users. It allows packet-based networks to carry voice, video and data. As a protocol, SIP can establish sessions for features such as audio/videoconferencing and interactive gaming and call forwarding, allowing flexible deployment over IP networks. Because SIP is an open standard, SIP applications can be rapidly developed and deployed lowering overall cost. Additionally, any vendor’s SIP application can use the Enterprise-CS MPG for session control. SIP trunks are currently changing the business model of telephone companies. Before SIP, a customer would order trunks from the telephone company. The telephone company, in turn, would run copper to the customer site and charge accordingly. This creates a long term, fixed relationship between the telephone company and the customer: if the customer wants telephone service, it must be ordered through the telephone company. SIP trunks, however, remove the inflexible relationship between the telephone company and the customer. With SIP, customers are free to choose their broadband service (i.e., xDSL, cable or VPN) and purchase their trunks from a variety of SIP trunk providers. This eliminates the single-source provider, and gives customer the freedom to choose the service providers that best suit their business needs. H.323 Like SIP, the H.323 protocol is used for on-demand conversations. Whereas SIP’s primary design was open source communication amongst dissimilar applications, H.323 was designed for real-time voice and video conferencing. Much narrower in scope, the H.323 stack places an emphasis on voice quality first, followed by video quality. H.323 is an open standard and enjoys the benefit of a large development network. Software developers such as Microsoft developed thin, powerful H.323 clients. Microsoft NetMeeting is an example that deploys real time video conversation over an IP medium. The ability to videoconference multiple parties using a non QoS network (i.e., the Internet) is H.323s primary strength. VoIP The Enterprise-CS Multimedia Protocol Gateway also provides a VoIP stack to deliver TDM quality voice applications. The unique ability of the Enterprise-CS is the full feature set available to VoIP users. Every feature available to the TDM user is available to the VoIP user including automated attendant and ACD. Using QuadFusionTM Technology, VoIP users can literally be located anywhere in the world. To the end user, this feature offers tremendous savings. Call centers, for example, can be centrally located with remote agents spanning the country. Agents simply use a VPN connection to access the Enterprise-CS MPG regardless of their location. TDM Time Division Multiplexing has enjoyed over (20) years of development and refinement. TDM’s stability and feature set are well understood. However, it is important to understand that QuadFusionTM Technology provides a bridge between the IP based protocols and the TDM features. The conversion from IP to TDM and back is seamless within the Enterprise-CS MPG. This ability allows VoIP applications to communicate with TDM resources with no degradation in voice quality. The ability to support IP telephony features is key to users with existing TDM systems, allowing them to leverage their current infrastructure and still use IP-based applications. Often, TDM users give up some features when they make the switch to an IP based protocol. With QuadFusionTM Technology, this is simply not the case. The Enterprise-CS MPG provides the ability for end users to purchase the most appropriate solution with the flexibility of moving to an entirely new technology at any time. Because the Enterprise-CS Multimedia Protocol Gateway integrates four protocols at its core, each provides a robust, stable feature set. Moreover, any of the four protocols can be mixed and matched. For example, a small, (12) person startup business begins in Austin, Texas and needs a basic business telephone system. For cost reasons, the business uses the Enterprise-CS MPG as a TDM voice telephone system. A year later, the business flourishes and now has (30) employees at the Austin office and another (6) in the new Miami location. Leveraging the initial cost of the TDM resources, the business decides to keep TDM applications in the Austin office. The Miami location uses SIP stations and ties the Miami office to the Austin office using VoIP over a VPN circuit. Each day, the two offices conduct a videoconference using H.323. This is an example of the power of the Enterprise-CS MPG using QuadFusionTM Technology. Summary OK, So Right, Can’t Any Provider Do This? H.323 Server SIP Server VoIP Server TDM Server
