To make VoIP calls, routes connected to operators are required, which provide the outputs for data transmission.
VoIP is the technology that allows the transformation of analog signals into digital ones. In this way, call audio can be converted into digital data, enabling the traffic of these packets via the Internet.
This allows companies to receive and make calls using the internet, using only the contracted email list usa data package. With the advancement of technology and increasingly faster broadband connections, VoIP calls now have good sound quality and stability, both for audio and video calls. However, all of this is only possible thanks to the connection made by routes between a telephone exchange (provider) and its various extensions (users). There are currently several technologies for this process, each with advantages and disadvantages. The main functions of the routes are:
Number bina, i.e. caller ID;
Analysis of the number called, with identification of the call as local or long distance;
Selection of the best available path for the connection;
Call forwarding.
Furthermore, they also directly interfere with the quality of audio and video transmission. Currently, the routes are divided into CLI and ITX.
VoIP Outbound Route Types
Currently, there are four routes available for operators to transfer their data.
"CLI Route
Used for both international and national calls, CTI routes feature premium digital interconnections and open bina, meaning the company's contact number is displayed to the user. For companies that want to identify themselves in their contacts and want a stable, high-quality connection, CLI routes can be very useful. However, they cannot be used for emergency calls and calls with 0800 and 4000 prefixes.
ITX Route
The ITX route, or bina 0 route, has the same quality as the CLI, with the bina being the difference between them, since in the ITX, instead of 2, 1 or no zeros are used before the contact number. This allows for faster identification by the customer, through the pattern 0 (zero) + DDD + Number. In some cases, the number 0 (zero) does not even appear. It is also possible to offer standardized service, since all calls made by operators use this same pattern. With this route, unlike the CLI route, it is possible to make calls to emergency numbers with the prefix 0800 and 400 and customers can identify the city from where the call is being made.
