The Limitations of VoIP – Thus Using IICalls is Naturally Better

Posted on Sep 16,2011 By Admin

What Is VoIP? VoIP (Voice over Internet Protocol) is simply an alternative way of making calls. It is also referred to as Internet Telephony. The difference is that you do not necessarily need a telephone set to make calls, and the call is processed in a very different way than the conventional mobile or landline call. VoIP technology has become increasingly popular because it makes calling cheap, and sometimes even free. Before we go into the disadvantages and limitations of the VoIP technology, let us take a quick look at how it actually works.   The Anatomy of a VoIP Call VoIP was invented much earlier than you would believe. In 1973, ARPANET pioneered the capability of sending voice across a digital network. This was limited to the ARPANET network grid only but there is no doubt that the ARPANET people were the first ones to invent VoIP technology. The first VoIP transceiver was built and patented by a company called Vocal Tec (founded by Alan Cohen and Lior Harmaty) in 1989. Here is a simple explanation of how VoIP telephony works:

  1. First, voice is converted into digital format in the form of bits or packets of information
  2. These packets are compressed (to save space and bandwidth)
  3. The compressed data packets are sent over the internet (not in series but in a different order)
  4. Usually, the packets are sent multiple times to cope with packet loss along the way
  5. Once all the packets reach their destination, they are first streamlined, then converted back to voice and heard by the person on the other end

  The Drawbacks of VoIP We have listed eight glaring limitations of the VoIP technology Limitation 1 – No Power, No VoIP! VoIP phones, and their associated technology, run on electronic systems. Thus, if there is a power failure, the VoIP phone will not work. Limitation 2 –Call Quality Deterioration Packet loss is an integral part of internet data transfer and VoIP inevitably runs the risk of significant drops in quality. Voice quality deterioration can occur for a number of reasons: from packet loss (which is just about OK) to fluctuations in internet speed and slowing down of computer for of any other reason (which is certainly not OK!). Limitation 3 - Different VoIP Protocols Do Not Work Together There are a number of VoIP protocols in effect today, and any two different protocols do not work together. Thus, say if your phone is using protocol X, you can only make free or cheap calls to another phone using protocol X. And, if you are using VoIP software like Skype or I call, you can only call another person using the same software. Limitation 4 – Inability to Call Emergency Service Numbers Since VoIP phones cannot be located to a physical address, they may not work - or have limited capability - with short code numbers (like 911 in the US). Providers are trying to overcome this issue by assigning a physical address to the phone number, but there is still much to be resolved in this area currently. Limitation 5 – Low Internet Speed Means Bad VoIP VoIP technology requires high speed internet to work effectively. It works quite well with DSL/ADSL and Broadband, but the technology has shown poor performance on dial-up and satellite internet connections. Why does VoIP have issues with satellite internet? Because it needs a latency of less than 200 milliseconds, and satellite latency is more due to the length of time taken for the data to travel from earth to the satellite and back again. Limitation 6 – Degradation of Network Performance When Using VoIP VoIP requires a lot of bandwidth, and this can cause disruption to your other tasks or to other users on your network. Conversely, if you are already using lots of bandwidth for other tasks the ability and clarity of your VoIP call will not be good. Finally, a high speed internet connection is required at both ends to maintain a smooth VoIP call. Limitation 7 – A Number of Internet Issues Can Cause VoIP Havoc The way in which the internet works raises some inherent issues to VoIP.

  • Phase Jitter - the sporadic shortening and lengthening of signal – jitter disrupts VoIP data
  • Packet Re-ordering – packets do not arrive on the destination in the expected order –VoIP software gets confused and you get a breaking of voice
  • Packet Error - multiple packets of data get degraded on the way to the destination – degraded packets of voice data = degraded VoIP call
  • Packet Loss - some packets of data are inevitably lost along the way - VoIP signal bears the burden

Limitation 8 – Limited Connectivity on Cellular and Landline Phones in Multiple Countries A VoIP service provider will place certain restrictions on its service offering. This can include free local calls only, or free international calls to only a very limited number of destinations only, or indeed the calls may be limited to landline phones only. And even then, the call works best as a ‘VoIP phone to VoIP phone call’ or ‘VoIP software to VoIP software call’.   An Alternative to VoIP Calls There is great demand for cheap or free international calls

  • With crystal clear voice quality
  • With the ability to call virtually any international landline or mobile number
  • Which can be made right from the user’s mobile phone, irrespective of location in the UK
  • Which are not limited by weaknesses listed above for VoIP

IICALLS have come up with the perfect solution… So why waste any more time when you can MAKE FREE INTERNATIONAL CALLS FROM THE UK NOW!

Top 5 Telecoms Predictions for 2012

Posted on Sep 16,2011 By Admin

Roland Emmerich (Director) and John Cusack (Lead Actor) from the movie 2012 may have led the world to believe that the end is just round the corner. Whether that is true or not will be decided in a few months’ time. However, we have compiled a list of predictions for the telecoms arena for 2012 which may have the same impact as tsunamis and quakes in shaking up the sector. Cloud computing, 4G, video and wireless data trends - as well as some changing business models are what have spurred our interest into creating this list of predictions. Since the UK is one of the world’s largest markets for mobile and telecommunications, we may be well on the way to seeing some major changes to our ‘tele-connected’ lives.   PREDICTION 1 – The End of Smart Phones What we call high-end telecom devices today may well become obsolete by the end of 2012. The availability of high speed internet through 3G, Wi-Fi and broadband, coupled with the lightening fast development of operating systems, will soon make all devices smart. New devices which will primarily be specialist internet devices with voice + video calling as their second important function will probably make today’s smart phone not so smart after all. PREDICTION 2 – Wireless Operators Will Push Netbooks With the advent of cloud computing, the demand for seamless sync between different devices and the increasing use of social media networks as the primary communication tool, we expect that Wi-Fi operators will push the use of netbooks. And the computer devices themselves will become smaller and smarter to adjust to customer demands. PREDICTION 3 – Investment Will Be Directed Into Bringing 4G Solutions Alive Many of the world’s top telecoms companies have already started deploying their 4G solutions and are already investing into backhauling projects that can handle increased data flow efficiently. At the same time, with 4G coming into the scenario, battery life for telecoms devices will need to improve. We predict that by mid-2012, much of the capital in this sector will be aimed toward deployment and sustenance of 4G solutions. PREDICTION 4 – The Complete Reign of Cloud Computing Apps The talk of cloud computing has been going on since 2009. However, we have reached a point where cloud computing has entered into the lives of most workspaces in our inter connected world. As companies outsource their most important productivity segments to developing countries, or those with more capable human resource, working on the cloud is quickly becoming a necessity. We predict that corporate spend on ‘being on the cloud’ is definitely going to rise within the coming year… and so should the providers’ efforts in rising to meet this high expected demand. PREDICTION 5 – Incremental Charging For Wireless Data Mobile and wireless providers have already provided users with unlimited usage plans and it has now become quite impossible for them to implement usage-based charging modules. The way for 2012, would be to offer best-effort-connectivity at cut throat competition rates and earn from incremental, value-added features. Thus, VoIP, video streaming, online gaming and such services that require consistent and high data flow will be charged premium levels.   The above predictions will, in our opinion, shape the telecommunications market in the coming years. Let us see how correct we have been in our assessments and how, if these predictions see light, the world changes with them. We, as users of technology and the providers of free international calls from UK will continue to provide our services to international callers in the UK.
