Whenever you are in an establishment, be it commercial, in a bank branch, offices, etc., I believe you will notice the existence of a digital phone, the network cable (as it is known) is connected to this phone, because it is, this is only possible due to VoIP or Voice over IP networks.
O Less wires brings to our readers some of its main advantages of this protocol that has been very useful not only for companies and also for residences, just so you have an idea the social network Skype or Whatsapp uses this protocol and it can work from computer to computer and computer to landline or even to mobile phone.
The protocol VoIP (Voice over Internet Protocol), guarantees Voice communication over IP networks, is a technology that allows you to transform audio signals, signals such as those from a telephone call, into digital data, which can, and are, transmitted over the internet or other computer network mode. that is based on IP (Internet Protocol). These networks can be of 2 types:
- Public Networks: The Internet represents the public IP network used for VoIP communications. The user must preferably have a broadband access (ADSL, cable, radio, Wimax, etc.) installed in order to make use of the VoIP service.
- Private Networks: corporate networks represent private networks used for VoIP communications, ranging from small local area networks (LANs) to large corporate networks (WANs) of companies with global presence.
The main advantages of implementing voice over IP protocol or simply VoIP are:
- Reduction in cost with connections: Now you can use your WAN to make long distance calls between the various units of your company, it reduces the cost with long distance and even local calls.
- Cabling Cost Reduction: Installation with VoIP can cut up to 50% of cabling costs because the same cable connecting the computer can connect the IP phone and computer. This primarily reduces the cost in new offices.
- Unified Voice Network: Now the voice network is integrated with your data network, this allows both remote offices and remote users to share the same network and the same numbering plan, allowing better control and management of these users and their devices.
- Advanced Voice Features (Feature-rich Communications): Now that data, voice and video networks are integrated, the user can take advantage of these technologies and add additional applications and benefits with this VoIP world. For example, based on the customer number a call attendant center can have all the data of the person, if it is registered, and even have information about negotiations passed automatically by the system, all generated from this integration of the network with the VoIP world.
- Open Standards and Compatibility between Various Manufacturers: As well as micros of different brands, such as Apple Lossless Audio CODEC (ALAC),, Dell e IBM can work on the same network, you can now choose open standards and make equipment from different manufacturers talk.
Another important point is that now the voice network passes through its LAN and WAN network, in this way allows the packets to be captured, decoded and their conversation is extracted or heard, so we have to ensure security when passing through suspicious environments use encryption techniques.
Of course, the concept is simple and ingenious, but how to make this happen is a little more complex, because the data network must be prepared to receive and treat the voice packets in the correct way, the voice packets must occupy a band that do not occupy your network, that is, using correct standards.
