A Brief Introduction to CLI and NON-CLI VoIP Routes

VoIP Technology & VoIP Routes

VoIP Technology the latest advancement in the telephony has changed the way of telecommunication for the world. The bringing together of traditional telephony and internet protocol has resulted in something that is not only user-friendly but also cost-efficient.

VoIP Routes are an important part of VoIP Technology. In VoIP, The audio signals convert to data packets for transmission in VoIP technology. These packets can travel over the Internet over VoIP routes, which essentially lets the VoIP call bypass the traditional telephone routes.

CLI Routes

CLI Routes are supposedly the best ones among all types of VoIP Routes. These white routes display the caller ID when the call connects to the recipient. The Caller ID visible to the receiver is actual information and not some random generic number.

The white routes are “legal”. By legal, it refers to the route termination on any end. All the connections associated with this route termination is in accordance with the law and also well connected to the telecom infrastructure of the concerned country.

However, the cost of CLI Routes is usually higher than other routes. And the reason behind its high price is primarily the quality. Although several other factors may also affect its final price tag.

NON-CLI Routes

Non-CLI routes are also known as grey routes. The calls terminated through non-CLI routes do not display any information about the caller. It usually displays a blocked call or some random number.

Many countries have restrictions on grey-routes. Due to the limited information available on the caller, the questions arise on its legality and its termination or any possible violations.

Usually, these routes have impromptu set-ups. In addition to that, they further use GSM or cellular service gateways for traffic handling and call termination over the destination telephone network.

Legal issues regarding VoIP Routes

In simple terms, the CLI Routes carrying and displaying the caller information are legal. While the NON-CLI routes which do not reveal the caller information are termed as illegal.

Example

Here routes are emerging from country X.

Traditional cellular or government monitored telecom services exercise monopoly in the telecom sector. And therefore the price of such traffic is very high. Therefore many individuals, businesses, organisations use VoIP Routers to counter this high-cost issue.

These people send the legal or the white route traffic of country X to the VoIP Routers via Internet (IP). The local PSTN terminates these at rates much lower than the international call termination charges. 

Therefore, on one end the routes are illegal or “black”, that is in other countries. But on the other end, they are “white”, which is in country X. And as a result, the route with one end black, one end white is then called a grey route.
