SIP Trunking & Data Open or Closed Internet? 14. June 2014 Kerstin (0) Data connectivity - without it SIP won't work It's common knowledge that Voiceflex's primary product offering is SIP Trunks and that will continue to be the case; however without a good data connection SIP will not work. There are many different forms of data connectivity but if you don't understand or sell data services you'll find it near impossible to sell SIP or hosted applications with confidence. If you own the customer data connection you will own the customer. They will consult with you on cloud based applications which will give you the opportunity to sell additional services. There are a number of words bandied about with reference to data connectivity with specific applications such as SIP which should be taken into consideration. Open & Closed Internet Connections The "Open Internet" is the Internet as we know it. It's open because it uses free, publicly available standards that anyone can access and build to, and it treats all traffic that flows across the network in roughly the same way. Customers can make their own choices about what applications and services to use and decide what lawful content they want to access, create, or share with others. This openness promotes competition and enables investment and innovation. However, the disadvantage of this is you never know the route the traffic will take. And if there's a problem within the ether there's nowhere to lay the blame, which is a problem for high dependence applications. The Voiceflex terminology for a closed connection constitutes the voice traffic never hitting the open internet from the local exchange to any of our data centres; it is never mixed with other traffic. A lighter quality of connectivity and if there's problems within the ether we can re-route traffic from one data centre to another. All down line ISP's used by Voiceflex have a minimum of two direct connections to the Voiceflex core platform in two different data centres. Any data connection supplied by Voiceflex for voice traffic, no matter what size will be on a closed internet connection; all other traffic will be routed over the open internet. We would always recommend (but never insist) closed internet connection for voice traffic.
