Our Technology

---

We use a private IP network and softswitch technology to deliver high quality, affordable communications services. We are a peer to the local phone company and support the primary line telephone services: E911, operator services, line features such as Call Waiting, Caller ID with Name, Three-Way Calling, Call Forward, etc. And unlike many VoIP companies who use the Public Internet to transport voice calls, where quality is "best efforts" and highly dependent on their broadband Internet connection, voice calls with Cbeyond travel over a dedicated IP connection and never touch the Public Internet; allowing Cbeyond to manage the Quality of Service and achieve 99.999% availability.

Here is how it works: At each of our customer locations, we install and manage a Cisco Integrated Access Device (a router about the size of a pizza box), which connects to both a customer's existing phone system and LAN. We send our IP traffic across our private Cisco-based backbone network, while handing off Internet data to our Internet service provider partners and phone calls to the Public Service Telephone Network (PSTN). No voice traffic ever goes over the Internet.
Networking Made Easy

Our VoIP network is more efficient than the old way of delivering voice and Internet services. To provide a bundled offering, traditional telecom service providers had to bring together two different networks to deliver their communication services - one for voice traffic, another for Internet traffic. But with our VoIP network, we're able to provide both voice and data traffic over the same network which allows us to dramatically reduce what it costs for us to provide these services and create a higher level of customer service. Our single network with one source of data and advanced operating support systems translates to faster and smoother installations; one number to call for support and online account management tools which put the power of moves, adds and changes into our customers hands - and at their convenience.
Typical bundled services versus Cbeyond Integrated Voice and Data Services

Our VoIP network also improves Internet performance for our customers by maximizing their bandwidth. The old way of providing services set a certain amount of bandwidth for voice traffic, and a certain amount for data traffic. When phone lines aren't in use, all of the bandwidth reserved for voice is just sitting idle. But with Cbeyond's network, since voice and data travel over the same path, when voice lines aren't in use, the full T-1 connection is used for data transfer. We call this Dynamic Allocation of Bandwidth, and it means that our customers always get the fastest Internet connection possible.

But the benefits of our network technology don't stop there. By creating a network that talks the same language as the Internet (even for voice traffic) we'll be able to deliver future business tools, software and Internet advances over our network directly to our customers. So they can feel confident that our technology will not become obsolete in a few years, but rather will be the foundation for future advances for their growing businesses.
