  1. 1. ViBE – OverviewVoice & Data on onelink with no effect onvoice quality
  2. 2. Overview In principle the idea of VoIP is great, reducing costs and integrating voice with your existing data infrastructure. VoIP allows you to get rid of PSTN lines and PBX systems meaning a big reduction in management and maintenance, which, most importantly cuts your costs. But while VoIP undoubtedly brings many benefits, users still have to make a number of compromises to reap these rewards. In reality VoIP suffers from one major ViBE effectively creates a connection overBY ANALYSING EACH problem; call quality quickly degrades over any link (ADSL, 3G, ISDN or satellite) thatVOICE DATA PACKET, low bandwidth links.

Once the number of calls increases, and data is also sent over the link, then VoIP ViBE removes the bandwidth problems call quality starts to degrade. that have always been associated with VoIP, allowing calls to be carried over Compressing the voice data would seem v voipex x cost effective ADSL. like the most obvious way of getting more VoIP calls across the available bandwidth, ViBE finally delivers VoIP without compromise. however such compression is detrimental TELECOMS TECH How ViBE Works to call quality. ViBE tackles the problem in a much more effective way. By analysing For any VoIP call to be of a high quality its each voice data packet, stripping away voice data needs to flow continually from the unnecessary data, ViBE can send an point to point. Once the flow of voice data unprecedented number of VoIP calls over is interrupted the call becomes jittery and a data network. both participants are likely to find it hard to understand what the other is saying.
  3. 3. ViBE – Benefits60 simultaneous calls over an average UK broadband connection
  4. 4. Benefits ViBE’s main benefit is its ability to use standard ADSL (broadband) connections to carry a high volume of VoIP calls simultaneously - and all at business class quality. The number of calls ViBE can carry at once is dependent on the bandwidth available. But 60 coexistent calls plus other data - like email and web browsing - is possible based on the UK’s average upload speed of 768Kbits per second as at February 2011. By taking advantage of ViBE’s ability to is approached. Problems such as pops, use ADSL you can avoid IP infrastructure crackles, and even gaps in speech can upgrades when making the move to VoIP. become evident. ViBE guarantees a high ViBE lets you maximise the use of your quality of all calls regardless of bandwidth. existing IP infrastructure, with no need ViBE reduces the time your voice takes to get for an expensive bandwidth upgrade to to its destination.
