Originally, Public Switched Telephone Network or PSTN was responsible for developing the Caller ID feature. Although this system was initially used by the public telecommunication service, other sectors greatly included this feature in their services for its usefulness.
The Caller ID feature has been used for collecting data from inbound calls. That is why this system was able to grab the attention of many types of businesses. The feature was becoming popular for its improved responsiveness to simultaneous calls. We will discuss these two VoIP routes in detail in today’s article.
What is a CLI route?
One of the most popular VOIP routes in the telephone service is the CLI or Calling Line Identification route. The other abbreviation of CLI is Calling Line Identity. This type of telephony service can be used with both digital and analog telephone services.
In the VoIP CLI route, the source of the call will be identified; whether it is a person or a business institute. As a result, the name of the caller or the organization along with the phone number will be displayed when there is an incoming call.
These routes are labeled as ‘White’ by the governing law of the country. It means this type of route is legal to use. The government takes the responsibility of terminating such routes on any end. Aside from this, these routes are directly connected to the country’s telephone infrastructure.
A user can enjoy international audio quality in calls in these VoIP routes. Also, these are best among all types of routes for providing caller information. As the governing law of the country is responsible for handling these caller routes, you will face no problem in call quality and other technical aspects. However, you have to count a large amount of money to get all these features.
The Use of Calling Line Identification or CLI –
The importance of CLI is increasing day by day. Whether it is personal or professional, the use of CLI has increased like never before. It is because of the many advantages of CLI routes over the traditional telephone system.
- Telemarketers
For many purposes, the telemarketers want to hide their identities and use the organization name instead of direct phone numbers. However, it is inappropriate in the view of the country’s law as it is considered spoofing.
But an organization has the ability to do this by taking CLI services. Therefore, telemarketers can hide their identities while obeying the governing law.
- Internet Service Providers
Internet service providers want to save an account from unauthorized calls. That’s why they use CLI routes to their consumers through remote services. There are also other reasons that internet service providers use CLI routes. For instance, when they customize their dial-up systems to show specific caller ID strings when someone calls.
- Mobile Dealers
In order to connect caller IDs to voice mail numbers, mobile dealers use CLI routes. Therefore, calling line identification is crucial for the voicemail option. With this feature, the voicemail automatically connects to the associated number without any password or authentication. Unfortunately, this service is no longer used for the frequent reports of spoofing.
The technology has been replaced with a newer and more secure version.
What is a Non-CLI route?
Unlike the CLI route, this type of VoIP termination route doesn’t reveal any caller information. At the time of caller termination, a random or blocked call will be displayed. When CLI routes offer excellent quality in calls, the quality of calls with Non-CLI routes is also noticeable.
Both of these VoIP caller routes follow an international calling standard. On top of that, Non-CLI routes use cellular services like GSM to handle traffic and terminate calls over the regional telephone network.
Most of the countries of the world consider the Non-CLI or Non-Calling Line Identification as ‘grey’. This type of VoIP route became illegal in many countries due to not showing proper information of the caller ID and violating the possible termination process.
It doesn’t necessarily mean the quality of calls will always be good. As Non-CLI routes are marked illegal, you may often face a lack of quality calls and you may not be able to make a call at all depending on the restrictions of your country.
CLI Route and Non-CLI VoIP Route: What are the differences?
After reading the definitions of CLI and Non-CLI VoIP routes, you already understand that CLI and NON-CLI routes are not alike. Let’s see the difference between these two routes –
| CLI Route | Non-CLI Route |
| Such routes are declared legal by the governing law | Such routes are declared illegal by the governing law |
| CLI routes are marked as ‘white’ in most countries | Non-CLI routes are marked as ‘grey’ in most countries |
| This type of route offers superior audio transmission | The quality of such routes are almost similar to CLI routes |
| This route remains connected to the telecom infrastructure of the country | Such routes don’t work with the telecom infrastructure |
| Not only GSM but also many types of cellular service gateways can be used to manage traffic | It only uses GSM type service gateway to manage traffic |
| At the time of termination, the caller ID and related information of the end-user is shown | At the time of termination, the end-users caller ID and information don’t show |
Bottom Line
You can’t think of doing VoIP termination business without VoIP routes. To terminate VoIP, these routes need to be channeled. For proper channeling and termination, various types of VoIP routes are needed, among them the CLI and Non-CLI routes are the most popular ones.
To start a wholesale VoIP termination business, we recommend getting the CLI routes rather than Non-CLI. Because your country may not approve Non-CLI routes, but they will surely approve CLI routes. Also, consult with a reliable VoIP service provider like VPSVOS to better manage wholesale VoIP business.
