COLT Telecom - VoIP Enabled WAN Solutions, a COLT Business Briefing

  1. 1. VoIP Enabled WAN Solutions: Is it time to converge your infrastructure? A COLT Business Briefing Data Voice Managed Services
  2. 2. IT’S SIMPLE: YOUR INFRASTRUCTURE SHOULD ENABLE YOU TO COMPETE Voice and data convergence technologies are real; they exist, and they are being put What we want to prove is that you need to address all the infrastructure issues to good use by enterprises of all shapes of sizes. The hype surrounding this subject right now, and avoid trying to migrate toward convergence in a piecemeal way has obscured a simple truth: whatever you decide to do about taking your without a clear plan. communications infrastructure into the future, it has to be right for your organisation, and enhance your ability to compete. This means that you have to start with a We believe that the best and most complete way to deliver a converged business and not a technological objective: you want to work smarter, faster, more infrastructure is to VoIP enable your data network. The following pages efficiently and productively, whilst cutting costs. make our case. In this briefing, we’re going to examine how you can reap the financial benefits of Convergence, whilst delivering productivity enhancements enabling your people to seamlessly make use of services like conferencing and unified messaging more easily. Convergence can help you compete more effectively giving you the flexibility and responsiveness you need to satisfy the demands of ever more sophisticated customers, suppliers and end-users. Convergence is not, as some have claimed, the Holy Grail for business in the 21st century. You need a cost-efficient and flexible infrastructure that gives you the right platform from which to do business in a smart and dynamic way. “The effort which organisations are currently expending on the transition to internet protocol voice will, in the long term, be rewarded with lower infrastructure opex costs, reduced telephony tariffs and increased productivity for their employees.” IDG, Managing the Transition to an IP network, 2007. 2
  3. 3. WHAT’S HAPPENING OUT THERE RIGHT NOW? Despite all the claims about an increase in agility and the ability to reduce costs, it is fair In our opinion, it makes sense to embrace IP telephony in stages, especially if your to say that the concept of Convergence, though much touted, has yet to really take off enterprise is large and complex. What we’re seeing is the deployment of IP telephony in any practical sense. in new sites and integrating them into the existing infrastructure. That way, you get to try out VoIP technology, learn how it works and then use its success as a model for That’s because moving voice from its own separate network and merging it with the total Convergence. data network is a big decision. So, by putting in place a VoIP enabled WAN solution you can open up the promise Enterprises are, despite impressive technological advances, moving to IP telephony of Convergence in an efficient and managed way. cautiously. IT managers are keen to maximise the investment that’s represented by their traditional voice systems (TDM), and they’re worried about quality of service and their own Let’s define what the solution actually is. lack of experience in using IP networks for both voice and data. To overcome those fears and concerns, enterprises often trial new technologies resulting in a mixture of networks being used. That caution doesn’t mean that the promise of Convergence isn’t understood and welcome: far from it. Datamonitor recently found that over 60% of IT decision makers have deployed some form of voice and data Convergence within their organisations. 3
  4. 4. WHAT IS A VoIP ENABLED WAN SOLUTION? The traditional model is familiar: voice and data networks are separate. Each uses discrete A VoIP enabled WAN also facilitates the integration of voice with a host of other clever equipment at different sites and is supported by different teams of people who are applications that make us more productive, flexible, mobile and, most importantly, experienced with the various enabling technologies. It’s a rigid set up that’s hard to change more responsive. or enhance and takes a lot of investment to transform. For many VoIP is the gateway to true Convergence: it’s the point where most The power and utility of the simple phone call has not been diminished by all the technology organisations start their journey. Most want to evolve into the future, gently nudging that’s come out over the last two decades. All the surveys show that the cost of calls makes their people and systems into a new way of working and then continue to build on up a major element in the operating budgets of all kinds of organisations.Voice over Internet each success as they reap the benefits of each wave of change. Protocol (VoIP), on the other hand, turns voice into digital packets and sends them out across the data network. So, VoIP, which is often facilitated by the purchase of a new PBX, It makes sense; VoIP is the perfect place to start as you migrate to a converged future. enables you to connect to the “PSTN” at an IP level. Access to your network is converged. Your IP WAN can now be used to carry voice calls within sites and to move “off-net” voice around your network using VoIP to deliver those calls for less. You can, therefore, remove or reduce the need for separate voice and data circuits. Traditional Model – seperate voice and data networks Converged Model – voice delivered across the data network 4
  5. 5. IS YOUR NETWORK READY FOR IP VIDEO? IP Video is usually discussed in the context of wide area communications or providing videoconferencing between distant sites yet the bulk of IP video traffic is generated from video on demand and videoconferencing applications that are being layered on top of todays converged voice and data IP networks. With recent developments IP video streaming is adding to an already large and complex matrix of traffic patterns and logical networks, with unique requirements and attributes, which propagate throughout a converged network. All this has the potential to drive up operational and network capital costs - if not planned carefully. Preparing a corporate network for IP video can be a daunting task comments Swartz, but it is necessary. IP Video offers a wide range of corporate value including economic and productivity advantages. He continues for many business and IT leaders, IP Video is an important component in their corporate Green, risk management and physical security and marketing strategies. Traditionally broadcast and videoconferencing services have not been integrated; they were physically and logically separate networks and services from both each other and other corporate networks. The value proposition for the video services of the 90s were mainly economic (reduced travel expense, increased productivity, etc) but they lacked video quality, ease of use and subsequently broad adoption. But video conferencing and in particular IP Video is fundamentally changing access, usefulness and quality as IP video is layered on top of a converged network. IP video is the enabler for a wide range of new video communication and collaboration services where video and audio quality is now outstanding and ease of use has been radically simplified. IP Videos value proposition to business and IT leaders is multi-variable. IP video is not just delivering the traditional economic and productivity advantages comments Swartz. He stresses that as energy costs rise, macro economic conditions worsen and airport travel security requirements consume more time spent per trip, the benefits from IP videoconferencing dramatically amplify e.g. reduced personal and corporate carbon footprint. Professionals are beginning to view IP videoconferencing solutions as economically feasible, commercially smart and corporately acceptable. So with the advent of IP Video, network infrastructure decisions have far reaching consequences and the capacity to offer huge benefits but to yield the expected benefits it is essential to carefully plan the deployment and implementation across a high quality converged network.

  6. 6. DELIVERING AGILITY AT LOWER COST IS THE REAL PRIZE Advocates of Convergence always cite the same business reasons in its favour. It’s important that these are defined in terms of the specific ways that an IP WAN can deliver them in the real world. Few talk about the fact that there are up-front costs, or `the need for new technical skills to make convergence work. You have to take into account the issues of service levels and reliability as well as security. You need to make the most of your existing investment in TDM, and work out the best way to migrate. We’ll discuss some of those points later, but first let’s look at the main business benefits that can be achieved: Cost Efficiency Flexibility Productivity » The old way of working used two distinct sets of technology, » In the past, dual networks required a lot of infrastructural work – » More and more enterprises are increasing their productivity by with multiple wires to every desk, and costs associated with new lines, new hardware and constant software changes – but a enabling workers to operate remotely.

  7. 7. DEPLOYMENT OPTIONS The business justification seems clear, but you still have one of three options: you can do So, at some point in the very near future you’re going to have to make a decision nothing; invest in a new IP PBX only; or converge your infrastructure with a VoIP about VoIP and, possibly, convergence. Do you resist the wave of enthusiasm for enabled WAN solution. both, or do you embrace the future wholeheartedly? As we said up front: we believe the third option is the best one for organisations seeking The VoIP enabled WAN solution enables you to move into the future at your own pace. to achieve all the benefits we’ve described. But, it makes sense to look at the case for choosing the other two as well. But who can you trust to get you there? Should you do nothing? You can keep on working with separate voice and data networks and avoid any complications that might arise from moving voice onto an IP network. But how long can that last? Your competitors will be cutting costs and becoming more productive whilst you are inhibited by the structural limitations of running two separate networks. Should you just buy a new IP PBX? That means your new IP PBX works on your existing infrastructure. But to get the most out of moving to IP you have to consider your entire infrastructure. Purchasing an IP PBX and connecting it to a TDM line without an efficient IP gateway, using conventional instead of IP handsets, does not get the most out of your IP PBX or the potential of VoIP. Of course, this could form an interim step towards integration. Do you opt for a VoIP enabled WAN Solution? You can only reap the business benefits of convergence once you address the issues right across your infrastructure. This does not necessarily mean doing everything at the same time. Equally, because a company needs to consider the network, the applications and the processes that they wish to use, it’s a valuable exercise in creating a clear plan for evolving your IP WAN. 7
  8. 8. WHO CAN YOU TRUST TO DELIVER? Voice communication is such a vital business tool. However, with well managed You have to check their technical competency, and ask whether they can provide a service level agreements struck with the right provider, organisations can smooth their truly end-to-end service.

Clearly define the CSFs and the answer to the question on the front page is – ‘yes’. success metrics and check how stringent the SLA’s are. It’s also important to be clear about the phases between now and full operation of your IP network. It’s important that you start to plan your migration. Our experience at COLT is that organisations that migrate site by site achieve the best results in the long term. You At COLT we believe we’re best placed to do all of the above. Let’s explain how. also need to think about your needs in terms of security and resilience, and ensure that you can be sure that you have the right business continuity plans in place. You then have to work out what skills you have in-house, and which you need from a specialist provider.
