VoIP Network

VoIP Call Flow Examples | QoS

Our VoIP network

Nationwide uses a proprietary network that optimizes both performance and economics for your VoIP business success. Using a geographically dispersed Super-POP architecture, Nationwide localizes traffic on the public Internet. VoIP calls are sent to the closest Super-POP and if need be, transported across the our private VoIP backbone to the called destination. Unlike almost all other VoIP network service providers, Nationwide does not use the Public Internet for inter-continental transport of your VoIP calls. Nationwide uses various Internet backbone carriers to effectively place our Super-POP's "one hop" away from all major Internet backbone carriers. In this way, Nationwide delivers the best-case customer experience, minimizing jitter, latency, and packet loss and maximizing call quality. The Super POPs are located in New Jersey, Chicago, Atlanta, and Las Vegas.

Redundancy Factors

On Nationwide's network, VoIP to PSTN transit occurs on Class 4/5 hybrid telephone switches designed for "Five Nines" reliability in carrier operation environments. All VoIP applications operate on geographically distributed architecture where paired hardware and software resources can assume all network traffic at any time. Our VoIP backbone is based on MPLS service operating on transport facilities obtained from two national carriers who operate diverse local and long-haul fiber routes. Finally, each MPLS fabric is fully meshed between each Super-POP.

VoIP Quality of Service?

• Quality of service or QoS, is of utmost importance for businesses. We use a two-step process to ensure great sounding conversations. First we evaluate the number of phone users and type of online activity. This will help us determine what type of internet connection will fit your business. Second, we will provide or recommend a router that will give your phone calls (a.k.a. voice packets) priority over any data transfer, thus providing QoS (quality of service). A router that can provide QoS is necessary because your voice and data are converged on to one network. You can read more about our network below.

In a prolonged power outage situation, is there a backup system in place to allow seamless and continuous service to all end-users?

• Our Super-POP locations are housed in carrier-class "Telecom hotels" or major Telecom "carrier quarters." Each facility provides redundant power, diverse fiber facilities and redundant environmental control services to ensure our goals of Carrier Class VoIP services are met. The Super POPs are located in New Jersey, Chicago, Atlanta, and Las Vegas.
