Transcript of "Vo ip basic altanai bisht , 1st sem ,college"

  1. 1. VoIP in mobiles   -ALTANAI BISHT  VELTECH MULTITECH DR Rangarajan DR Sakunthala ENGINEERING COLLEGE   Dept of INFORMATION TECHNOLOGY , BTECH 1st Semester  12/06/207
  2. 2. ABSTRACT Voice over Internet Protocol (VoIP) is the technology used to transmit conversations digitally over the Internet. This presentation describes VoIP and how it compares to traditional phone systems, the standards organizations promoting the technology, and what this means for you now and in the future.
  3. 3. CONTENTS What is VoIP ? How does it work? Basic VoIP setup Ways of using VoIP Technology Integrated Features Questions
  4. 4. What is VoIP…….? Voice over Internet Protocol (VoIP) is an emerging set of applications which allows you to make telephone calls over the Internet VoIP is a great money saver for both businesses and residential users VoIP equipment includes a broadband modem and an ATA (Analog Telephone Adapter) or IP phone.
  5. 5. Surprisingly the same as most mobile phones today…! Take your analogue voice and digitises it and then send it via a carrier.. Mobile phones use GSM and VOIP uses IP network.. Hence Voice Over IP. So instead of the phone breaking up your voice and sending it over the air, VOIP breaks it up and sends it over the internet. So if you can use a mobile you can use VOIP.. As for call quality.. Generally similar to a mobile phone call. Like mobiles though it can vary.
  6. 6. Ways of using VoIP Using your home phone: Using your regular phone and an adapter, Using an IP phone: When using a special IP phone, you don't need a separate ATA. Everything you need to use you r broadband internet connection Connect using your computer: If your computer has speakers, microphone, a sound card, and a high speed internet connection you can use your computer for VoIP.
  7. 7. Technology Audio is converted to digital by a process called encoding. This is the “voice” part of VoIP. Once audio is encoded, it can be transported via electronic means, such as the internet. There are rules, or protocols, that have been established for exchanging information over the Internet, the basis of which is called Internet Protocol, thus the “IP” in VoIP. VoIP is becoming popular as more and more people utilize broadband technology. Broadband technology is a large capacity data connection to your home or office that is “always on”. Examples are internet service provided by cable or digital subscriber line (DSL).
  8. 8. Technology Internet Protocol describes, among other things, how data is broken up into packets, addressed, and transported. In this way, you can use a single network to transport many kinds of data at the same time. For example, someone can be surfing the web while another person is having a VoIP connection.
  9. 9. Features Improved audio robustness Parked calls automatically return if left unattended Personal contacts can be called with specific services — for increased savings on long distance costs Voice commands. Use voice-activated commands to dial, transfer, and retrieve calls. You can also ask for the company directory or for free directory assistance.
  10. 10. Features • Voice dialing: Use your voice, instead of your phone keypad, to call contacts. This hands-free solution eliminates the need to memorize and press numerous key sequences. • Call routing options. Choose how incoming calls are answered. You can have the Automated Receptionist, official receptionist, or multiple users, route calls when they come into your business • Call status. Check in-call and parked-call status from the Assistant by viewing status indicators.. • Park music. Play an audio file callers will hear as they wait in park.
