Have you ever used a messenger or video conference application to contact colleagues or family? You must have done it often enough because it is free of charge and more practical to do. This technology is known as Voice over Internet Protocol (VoIP).
Technically, VoIP is a technology that allows you to communicate over long distances using the internet network. VoIP uses network protocols such as H.323, MGCP, SIP, RTP, SDP, or IAX. The following is information about VoIP to broaden your horizons.The practical options for the Virtual Phone system come perfectly here. One can contact the companies who provide this service and they can look for ringcentral vs other company’s services as well.
The function of VoIP
The primary function and advantage of VoIP are connecting people between cities, islands, and continents. It usually costs a fortune to call friends or family, especially if you live in two different countries. VoIP is a more affordable communication solution.
Along with the times, VoIP is now also able to transmit voice and video. VoIP development is also being carried out to carry out long-distance communication more smoothly, quickly, and without problems. Some examples of VoIP technology include messenger applications such as LINE, WhatsApp, and WeChat. Then, there are also video conference applications such as web meetings, Zoom, Skype, etc.
When described, VoIP itself has 4 different functions. Starting with the signaling function, where VoIP is in charge of receiving networks from the callers. After receiving the network, the initiation or delivery of the conversation takes place. That way, callers and listeners can communicate with each other with clear voice quality.
Then, proceed with the database service function, namely finding the location of the endpoint. In addition, this function also translates addresses used in two different networks. Another function of VoIP is bearer control which allows users to accept, reject, or hang up phone calls. Finally, a coded operation function transmits or converts voice into data packets and vice versa.
How does it work?
The analog sound taken from the speaker of the device will be converted into a data packet. Then, this data packet will be sent through a hub or router or ADSL using the internet network. This data packet will be sent to the destination, namely the device, from the recipient of the phone.
This data packet is sent to the remote destination after the analog signal is converted into digital data with the Analog to Digital Converter (ADC). When the digital data arrives at the other person’s device, it will be converted back into an analog sound with the Digital to Analog Converter (DAC). Simple enough, right?
Keep in mind that this VoIP technology depends entirely on the quality of the internet network, both owned by the caller and the recipient of the phone. Now, several telephones are also able to connect to the VoIP network. The ability of VoIP to communicate with a Private Automatic Branch Exchange (PABX) allows telephone calls from a computer device to a telephone or extension number in the office.
The advantages of VoIP
In contrast to conventional telephones, VoIP technology is a more cost-effective solution. Why so? This is because you only need capital in the form of an internet network to be able to connect with the other person you are talking to. No need to pay phone bills and so on. This is also the main attraction of VoIP.
