Most of the business entities use multimedia and voice communication services over the Internet.
They use the terms Internet or Broadband Telephony, IP Telephony that refers to the communication over the public internet instead of the public switched telephone network.
VoIP stands for Voice over Internet Protocol. VoIP is much similar to our traditional digital telephony mechanism and the only difference is the medium of transmitting signals.
What are VoIP Services?
- As discussed in the introduction part, Voice over Internet Protocol (VoIP) is the telephony methodology like the traditional one but in which the digital information or signals are being converted into packets called IP packets and are transmitted over Packet-Switched Network
- VoIP has been implemented over several open and proprietary protocols such as Session Initiation Protocol (SIP), Real-time Transport Protocol (RTP), Secure RTP, Session Description Protocol(SDP), Extensible Message and Presence Protocol (XMPP).
- First-Generation VoIP providers have used Legacy Telephone Network, Second-Generation VoIP providers like Skype used the public switched telephone network (PSTN) that offer free calls benefits, Third-Generation VoIP like Google Talk has adapted the Packetized Voice Telephony (Federated VoIP).
- Video Calls
- Instant Messaging
- Better Sound Quality
- Voice integrated data transfer
Working of VoIP
- VoIP uses Codecs which encodes audio in Audio Codecs and video in Video Codecs.
- This encoded audio and video are then encapsulated in the packets.
- Then these packets are being transmitted over the IP network.
- At the end of the communication, the audio and video are decoded back into its original form.
Pros of VoIP Services
- No extra charges are involved other than the Internet for making calls, e-mails or for any communication that takes place over the Internet.
- VoIP helps to reduce the expenditure that is required to build network infrastructure.
