Voip calls: how it works and what are the advantages ?

VoIP for Voice Over Internet Protocol or Voice on Internet Protocol designates technology that allows you to receive and make phone calls using the network. It is a set of protocols that work together to offer internet telephony functions similar to ordinary telephone lines or RTC (switched public telephone network).

VoIP telephone service gives flexibility and mobility much greater than traditional telephony. France has also planned to close the traditional RTC network to replace it with the VoIP system.

This end of RTC pushes many professionals and companies to question the operation of VOIP calls and to seek how to integrate them effectively into their structure.

In order to help you, we explain to you concretely what VoIP calls are, how to put them in place and especially how to enjoy all their advantages !

What is a VoIP call ?

A VoIP call is a communication system where audio data is encapsulated and compressed in small data packets. These packages then travel through different networks until they reach their target (most generally the IP phone or computer of the recipient of the call). The packages are then “decompressed” to find their audio format.

All these operations take place in real time and without latency. For users, the functioning of VoIP is therefore completely transparent, it does not matter that the caller or the recipient uses the switched network.

How to call a VoIP number ?

Calls to a traditional line

Passing a VoIP call is as simple as calling on a traditional line. If you call lines always connected to the switched public telephone network (RTC), you simply have to type the phone numbers of your correspondents.

The only difference is that non -encapsulated audio data transit with a VoIP gateway. The latter converts digital audio into analog without you or your interlocutor noticing any difference in the quality of call.

The most frequent questions about VoIP

What is the difference between Voip and ToIP ?

VOIP concerns all communication transmissions between employees, companies and operators. This is a protocol to transfer audio communications (and sometimes video) to the network.

For its part, the ToIP for Telephony Over IP operates the entire telephony system on the IP network thanks to an IPBX. This is a structure that replaces the RTC network with a fully computerized solution and therefore requests a substantial investment.

What is an IPBX server ?

An IPBX server for the Internet Protocol Branch Exchange uses a company’s internet network to manage phone calls. The IPBX system is similar to a proxy server which brings together a directory of all phones and users and allows to connect and route the calls.

IPBX is the central element of Toip and Voip solutions, but it can be replaced by a hosted solution: the Cloud PBX which allows you to delete installation costs.

Why the voice on IP ?

We speak of voice on IP, because with VoIP the voice is literally carried by the Internet network. It is first transformed into electronic signals and then software, the codec, converts these signals into computer language (binary). On arrival the signals are new converts into audio messages.
