EOH Network Solutions (EOH NS) believes its voice over IP solution, using Voice over IP Broadband Enhancement (ViBE) technology, will provide clients with greater flexibility in terms of choosing a cost-effective alternative to traditional fixed-line telephony infrastructure.
The technology, patented by Voipex, allows a more effective use of bandwidth for voice and data applications, resulting in a higher density of voice calls, security and resilience.
"We considered a number of different protocols and implementations before settling on ViBE. Traditionally, implementing VOIP on a data network was complex and required a very specific bandwidth calculation, based on a number of different factors, which included the last-mile access technology deployed and codec used on the network. The complexity was compounded with rules limiting voice to 70% of the available bandwidth. This led to poorly designed voice over IP implementations, or ineffective use of bandwidth. With ViBE, we're able to get the bandwidth usage of a single voice session down to 8kbit/s per call using the G.729 codec - thereby effectively allowing up to 300% more voice channels on the same amount of bandwidth required a year ago," says Brandon Dienar, Sales Manager of EOH NS.
EOH NS is delivering the Telviva N+ VOIP solution from within its carrier environment at the vendor-neutral data centre facility at Teraco. The platform provides organisations with a complete IP gateway that converges traditional voice, VOIP and GSM.
"We view voice as an important part of our strategy. We have a dedicated voice engineering team of 20 engineers who have developed the solution, support and manage the voice aspect of our network and they work closely with our voice product managers to ensure that we are meeting the client requirements and delivering a quality product to the market. In line with this, we have also opted to go with a focused voice rollout, using a dedicated network design approach, keeping voice traffic separate to data on the client's network by means of a dedicated last-mile for voice traffic. This ensures a consistent experience on the voice quality regardless of whether there's congestion on the client's data network. With ViBE and last-mile access pricing having dropped significantly, we can do this at a very economical rate. Depending on the client's call volume and usage patterns, average savings of 25% can be expected compared to their existing Telkom billing," adds Dienar.
The solution is already deployed at 1 400 sites locally, servicing 19 000 extensions and carried 4.5 million voice minutes for a number of large enterprise clients as at August 2012.
