Lets address some points that should be taken under consideration for IT managers looking at packetized communications for their Enterprise. Below are the highlights and my thoughts:
I couldn’t agree more! SIP is a protocol used to establish, teardown, modify, etc communication sessions. It’s very diverse and relatively simple when compared to past mechanisms. Most importantly, it has become the defacto standard within the world of telephony. There’s native SIP support in nearly all the major vendors that supply VoIP gear. (Cisco, Avaya, Siemens, Microsoft)
Consider The Benefits Of Hosted PBX
This topic has be discussed numerous times in the past, and even before that within a TDM context (PBX vs. Centrex). The thing that’s different within an IP context is the feature and functionality available. When comparing a PBX to a Centrex offering, one key difference was additional feature and functionality in a PBX. Centrex offerings didn’t have the same “whiz-bang” features. In today’s Hosted Telephony offerings, there’s near feature parity, so the key determining factor becomes cost of ownership.
VoIP (or Telephony) MUST be seen as a stepping stone to the ultimate goal of Unified Communications. IT managers should consider the roadmap to UC when choosing a Telephony solution. Real-time communications need to become multi-modal, meaning there should be options to transition communications from IM to voice to video to online collaboration on a document, and then back again – all within the same context and within a common look/feel.
Though the issue of Network Address Translation (NAT) is well known to negatively impact SIP sessions, the real point for consideration here for the IT Manager should be around considering the deployment of a Session Border Controller (SBC) within their Enterprise as part of an overall design.
There are more ways to packetize voice and video communications than one can shake a stick at. The author points out the predominant technologies of G.711 and G.729. Issues of bandwidth consumption and quality of user’s experience must be balanced. Generally speaking, the more bandwidth consumed, the better the experience. But the more bandwidth used, the greater the cost to upgrade the LAN/WAN infrastructure to accommodate. If you skimp on cost, the result would be poor quality, and then adoption and experiences would suffer. It’s a delicate balancing game.
• Make sure to have 100k in bandwidth free and available for every conversation when determining whether the enterprise really has enough bandwidth for VoIP. With multiple calls made from one location a simple DSL won’t cut it.
• Get VoIP phones that are both wired for Ethernet and wireless for Wi-Fi connectivity. That way, people can wander, and all internal calls within the building are free of charge because they stay on the network. Check the mobile voip solutions, few of them even work without need of data plan.
• Make sure the vendor is going to be around to support the purchase. An older vendor with roots, commitments, and financial means is an obvious choice. A new vendor with strong management, skills, and reputation who proves out through considered research can also be a sharp choice.
Over the past 14 months i’ve met with many different customers at many different levels. One thing I continually do is talk about the benefits of converged technology such as VoIP and IP Telephony. The last few blogs have leveraged convergenced as a foundation for unified communications as a next generation service offer but in this post I thought I would try something different and revisit the benefits of some common technology – VoIP and IP Telephony.
Most people understand the benefits of transitioning to a converged all-IP environment. As more applications come onto the market and the technology proves itself, these firms will be able to avail themselves of the many benefits of such converged technology adoption.
· Offers advanced call routing and enables new applications to further customer service initiatives.
· Accelerates and facilitates the move from a legacy environment to converged networks.
· Anchors IP innovation across the enterprise, and helps deploy a web services infrastructure enabling rapid development of IP-based applications and services.
· Facilitates the deployment of real-time workforce collaboration tools, which fosters an environment of high worker productivity, innovation and information sharing.
· The market isn’t moving towards converged networks – it’s there! Therefore the adoption of IP and VoIP are foundational steps on taking you down that path.
· Voice over IP can bring customers the benefits of network optimization and greater value through the convergence of services over a single connection. One IP network will handle data, video and voice.
· It can reduce total spend on traditional telco services by converging voice and data onto one pipe, eliminating the need for leased line charges from a telephone service provider, since all calls are flat rate.
· Depending upon the design all calls may be on-net as is the case with Global Crossing’s VoIP Onnet services. Compared to traditional TDM solution with the exception of private voice networks the majority of calls may be delivered off-net and thus more costly to operate from a call perspective. Fully converged services extend the on-net “look and feel” through our enterprise VoIP network. Instead of building their own TDM networks and deploying proprietary on-net calling plans, customers will gain value by leveraging a service providers VoIP network such as Global Crossings.
· It can help lower cell phone charges by enabling worker productivity on the road and remotely.
· It reduces high toll, long-distance usage.
· It facilitates real-estate consolidations through extension and directory mobility by leveraging VoIP with “find me follow me services”.
· It reduces PBX support issues by migrating to fully converged network-based services that are centrally located.
· Packet-based voice traffic becomes just one application running over a multi-service network, allowing for more efficient bandwidth utilization.
· With dynamic bandwidth allocation technology in the absence of voice traffic the full network is available to data traffic.
· The move to IP telephony is a good first step towards convergence, and allows for more sophisticated network management by running voice over an existing data network.
· Converged networks can be more complex to operate – the LAN’s additional complexity needs to be managed. This complexity can be offset through a managed VoIP solution.
· The business processes associated with troubleshooting and managing network quality need to be well-defined.
· Depending on the age of the network already in place, the transition to IP telephony may require some additional costs associated with hardware requirements such as advanced telecom gear to replace older equipment as well as replacing the end telephone stations used for traditional telephony with advanced IP-enabled sets.
· Additionally, if power over Ethernet is chosen there may be additional expense associated with powering the handsets.
· Finally, VoIP requires advanced traffic management and statistical analysis on edge and core components in order to track and trend network utilization and problems appropriately. Such systems may not necessarily be in place which would require further network management software to be deployed.
There you have it …. some of the VoIP and IP Telephony benefits revisited. There are cetainly more but those are just a few that I captured this evening.
The cloud has been the source of clever headlines for a years now, but what are the experiences of the early adopters? Research firm TNS surveyed 3,645 IT decision makers around the world to find out.
The study, sponsored by CSC, found that the primary driver for moving to the cloud is not cost based, but a need for the business to be able to access information from anywhere on any device. A third of respondents cited this, or mobility, as the prime driver, with only 17% saying that cost was the driver. This reflects a larger trend towards consumerization of business as workers use a variety of devices to manage their daily work.
Interestingly only 14% of respondents downsized their IT workforce following an adoption of the cloud, and 20% hired more cloud experts. Perhaps because cost was not the main driver for adopting cloud services, many companies reported no cost savings, or minimal savings. Almost half of US small businesses and a quarter of US businesses reported no savings.
Differences in cost savings are marked, region-to-region, with Brazil reporting the biggest savings, with over 90% of businesses reporting savings and an obvious correlation in the research is that Brazilian companies prepared their employees best for the move, providing information and training. Security is perhaps not the huge issue that the industry believes, with only a quarter of businesses more concerned about security after adoption. Almost half of the well-prepared Brazilians are less concerned about security after adopting the technology.
The business opportunities for cloud are clearly in the small and medium business area, where the benefits are clearer and the resistance to the change is less but it is also an area where telcos are not in their comfort zone, according to a consensus at a recent STL Partners gathering.
Whether large companies, including telcos are themselves adopting cloud services is still being examined. Certainly, the risks involved in telcos outsourcing critical processes to the cloud will not happen overnight. Just because almost half of US Government agencies report that they have moved some processes to the cloud – as part of their ‘cloud first’ policy – does not mean that large companies generally are leaping onto the bandwagon.
It is interesting, and will be of concern to some, that the cost saving argument for cloud adoption appears to be flawed. There are, of course, those industry veterans who witnessed the same phenomenon when outsourcing was the ‘next big thing’ some years ago. For large companies, unless the processes being considered for outsourcing are working well do not go ahead, outsourcing a problem seldom works and as one European IT manager from a decade ago remarked “why add legal problems to technical ones – that is all you are doing?” Or is it?
In its life journey, telephony systems have traveled from plain old legacy systems to an era of advanced stage of Voice over IP communications supported by high-speed internet connection. Telecommunication feature requirement or demand has now moved to such a diversified stage that the business demand-supply chain keeps changing at a very fast rate. Let me to explain this.
As an example: A requirement or demand of a telephony feature like video conferencing is now no longer dependent on a particular way of implementation i.e. not only limited to hardware solution within an enterprise but have also available on mobile as an application software. It means that business solution of ‘video conferencing’ can be achieved via many dimensions like free soft-phone based, license soft-phone based, hardware based, Mobile/laptop based, or even home decor Television based.
This implies that telephony business must have dynamic business model and not sticking to particular solution. Business model must be capable to switch to alternative solutions at any moment. For big players this is not an issue of any concern, but small business players, must pick wisely what kind of telephony system they will use and what their sustainability is. They must think of moving their on-going business with telecom generations of high-speed internet and digitization.
In legacy telephony, business was oriented towards cost of each audio phone call, number of calls, and Local vs STD based calls, as this ware the core services available. Videos call at that time ware among major earning business solutions.
As a generation of telephony moves on, until 2.5 G to 3G, audio and video phone call is like default services and internet based, location based, on-demand or live streaming was on a high demand. At this stage, new business players who forecast this as an era of stating point of next generation telephony service were able to make a lot of money. Many entrepreneur and many small telecom businesses have grown up to support this demand both with hardware, software and as service.
Many software solutions and telephony applications were developed, protocols were defined and universal standards were placed. Businesses grew with software application around audio call, video call, conference, 3-way calling feature, announcement, advertisement service during telephony services. Hardware based solutions also grew in parallel and High-Definition quality were integrated with above listed telephony services. Small business which were software based have grown up and earned much, whereas big players have taken up this as a complete hardware and software solution, by building up of their own networks. Some business also grew targeting services of telephony application, whereas some targeted the support of telephony service, like Analysis and Analytical tools, testing tools etc. Legacy business was on backward compatibility support of these new telephony service.
At present telephony demand has changed a lot in its demand and implementation. From fixed hardware to mobile based app solutions. Business players have also re-shuffled and realigned themselves. Telecom operators are moving ahead to meet the demand with high speed internet solutions with legacy hardly contributing to a small percentage of profit. On other hand telecom R&D organisations / MNC have started working on next generation technology with high skilled human resources. Business players oriented towards software based adhoc service providers are also growing. Businesses are investing more on mobile based telephony solution like whatsapp, facebook, etc . A bulk of small business earning are also centralised around information on public platform and on advertisement. Telecoms are now moving towards IOT (internet of things) and wifi solutions. Hardware independent, time independent, resource independent fast and easy communication is needed with rich functions and high definition quality.
Small business players interested in telecom business must consider these changes in trends of telephony application demand and supply. Changes from fixed dialling system to mobile based automatic voice-recognition based high-speed internet service, must be analysed for any business investments. Legacy telephony in future is not going to last for couple of more years. SS7/ISDN based telephony system is going to vanish from market being replaced by high-speed and wifi solution.
Eventually telecom market is moving towards virtualization system capable fast and easy expansion of resource with change in demand, Big data and their analysis, single click software application supporting telephony functionality, hardware and location independent application and location-time applications. Those small business working on core legacy technology should try an attempt to move towards high-speed internet based telephony feature. Those small business working on hardware based legacy telephony should try an attempt to move towards digitization and integration within next generation hardware systems. Those small business working on services of legacy telephony should try an attempt to move towards adhoc or license free solution with telecom operator. Small business players interested in telecom business as a solution can work on providing mobile based soft-phone solution as a client solution. As side service they can provide VoIP data analytics, new VoIP features or Wifi solutions for middle business players. IOT – internet of thing is another major evolving in telecom sector, which small application and sensor based device communication are in trial, small and middle business sectors can also think towards this dimension of telecom solution. Telecom sector is vast and it depend so each business player’s vision and mission to work upon.
