Hey MI Fans,
VoIP or Voice over Internet Protocol is hardware and software combination that enables users to use the internet as a transmission medium for calls. This allows people to talk to one another long-distance and around the world without having to pay long distance or international phone charges.

What is Internet calling / VoIP
  • Calling through the internet is a methodology or technology which delivers Voice and Multimedia session over Internet protocol. The procedure involved in internet calls are similar to traditional telephone, signaling, encoding-decoding etc.
  • Instead of being transmitted over a circuit-switched network, the digital information is packetized, and transmission occurs as IP packets over a packet-switched network.
  • VoIP use ITU standard codes like G.711 for Standard for transmitting uncompressed packets, or G729 which stands for compressed packets. As well VoIP non-voice communications via the ITU T.38 protocol for sending faxes over a VoIP or IP network in real time.
Difference between VoIP & VoLTE
  • Since Technology is changing day by day as well communication is changing. VoIP (Voice over Internet Protocol) and VoLTE (Voice over Long Term Evolution) are two solutions for delivering voice calls over mobile devices, such as smartphones or tablets. But is always comes to our mind that what are the difference between VoIP and VoLTE.
  • VoIP sends voice packets over the internet and in the same it sends the data packets. So the device sents the Voice and Data packets in the same way and the packets get shuttled along the Internet by-ways. There will be no difference in transmitting Voice and data packets as both will get same priority.

  • Whereas VoLTE uses 4G networks for transmitting Data and Voice. VoLTE has the ability to carry voice and Data more than three times compared to VoIP.
  • Some basic difference in between VoLTE and VoIP is that VoLTE requires a QoS component. Voice packets for VoIP get sent along Internet nodes and are treated no differently than any other data.
  • VoLTE uses IMS and a separate radio frequency to help maintain the quality of the VoLTE transmission. With the advanced technologies, the VoLTE uses fewer resources which results that it takes less time to connect than a 3G call.

Is a VOIP free?
  • VoIP usually a cheap option but not completely free. It depends upon two factors that the type of call and the service is offered. It's free if someone calls over WiFi.
  • The reason to be chargeable that when someone does not have any internet connection or mobile dialer. As this connection requires an internet connection and mobile dialer or PC dialer, so calling from VoIP app to app is totally free. For such calls, the user requires an internet connection and mobile dialer on both sides.

What are the Advantages and Disadvantages of using VOIP?
  • As VoIP works by converting sound into digital voice communication and then transferring it through Internet broadband. It has several benefits for many businesses as well for personal use. It saves money, Portable, Flexible with multi-functionality.
  • It is much cheaper than a traditional phone. It uses a broadband connection to connect others. If someone has internet connection whether where he is there should not be any problems in terms of costs and connections.
  • Besides of making calls its also helps in video conferencing which help clients for growth in business.
  • As it requires an internet connection, so This works well for travelers who can call over wi-fi from anywhere. It's easy to add callers to a conversation and usually not limited by call minutes.
  • The call is not consistent if the internet connection is not stable which may hamper your computer performance too.
  • You always need an internet connection to make a VoIP call.
  • Without power VOIP phones are useless, so in case of emergencies during power cuts, it can be a major disadvantage.
  • Latency and traffic, No standard protocol is applicable.
