What is a VoIP number?
We explain everything.
Definition and basic principles
A VoIP number (Voice over Internet Protocol) number is a telephone number that operates via the Internet. Unlike traditional telephone lines that use the copper (PSTN) network, VoIP uses the IP network to transmit voice as data.
In concrete terms, with a VoIP number :
- You can make and receive calls via a computer, smartphone or IP-enabled phone.
- It’s not tied to a fixed geographical line: you can use it anywhere, as long as you have an Internet connection.
- It can be assigned to a person, a team or a function (e.g. “customer support”).
This type of number also enables calls to be managed via an online interface, with advanced options such as recording, redirection, supervision, CRM integration…
All without heavy hardware or technical installation.
Differences from traditional telephony
| Traditional telephony | VoIP number |
|---|---|
| Physical fixed line | Operates over the Internet |
| Mandatory equipment (PBX, fixed stations) | No equipment required |
| Slow, localized deployment | Quick activation, accessible from anywhere |
| Low flexibility | Highly adaptable (mobility, multi-device) |
| Few integrations | Compatible with CRM, business tools, etc. |
In short: a VoIP number offers the same function as a traditional number, but with more freedom, more control and fewer constraints.

How do I obtain and configure a VoIP number?
Migrating to VoIP telephony is a strategic opportunity. But to make this transition a success, it’s essential to follow a clear methodology. Here are the 5 key steps to obtaining and configuring a VoIP number perfectly suited to your needs.
1. Assessing your needs
First and foremost, take the time to analyze your current situation and your objectives.
To evaluate :
- Call volumes: how many users? how many lines?
- Business objectives: cost reduction, improved customer service, supervision, etc.
- Network infrastructure: sufficient bandwidth? Quality of Service (QoS) in place?
A stable, well-configured connection is essential for smooth calls
Portability :
- Mobile number porting takes 1 to 3 working days
- A landline number can take from 2 to 10 days
Ask yourself the right questions:
- Do you need a multilingual system? CRM integration? an automatic dialer?
- Would you like real-time call statistics?
It is this phase that will determine the choice of the most appropriate solution.
2. Supplier selection and registration
Once you’ve defined your needs, choose a service provider that meets your technical and operational expectations.
Key points to consider:
- Guaranteed call quality
- Encryption and RGPD compliance
- Native integration with your business tools
- Responsive human support
Plan your migration:
Internet connection installation times depend on your operator. Activation begins once the connection is available.
- An ADSL connection takes 2 to 4 weeks on average
- Fiber optics, between 8 and 14 weeks
Some platforms, such as Kavkom, enable activation in just a few minutes if the infrastructure is ready.
Tip: register at least 2 months in advance to avoid unexpected interruptions or delays.
3. Number acquisition and portability
After registering, you can order a new number or port an existing one.
Regulatory deadline in France:
- Fixed number: portability within 7 working days, with max. 4-hour break
- Mobile number: portability within 1 working day, also with max. 4-hour outage
Source: arcep.fr
To succeed in this step :
- Check the administrative information associated with your number
- Coordinate portability with your old and new suppliers
- Warn your teams in advance of any temporary outage
4. Technical configuration and integration with your tools
Once the number has been activated, configure your VoIP interface and connect it to your business software.
Steps to follow :
- Create users, transfers, queues, answering machines
- Connect the platform to your CRM, support or ERP software via API or native connectors
- Activate advanced features: click-to-call, call scripting, supervision
With a well-designed cloud solution, like Kavkom, activation is possible in a matter of minutes in simple scenarios; more time is needed for complex or multi-site integrations.
5. Testing, training and deployment
Before taking the plunge, take the time to validate the implementation.
To do :
- Test internal and external calls
- Simulate different scenarios (opening hours, transfers, absences, etc.)
- Correct any technical bottlenecks
Form the teams:
- Short 30-minute sessions
- Access to user guides and videos
- Appoint an in-house technical consultant
Allow at least two weeks for a complete and gradual transition
Porting or advanced configuration requests can extend this timeframe, especially for complex or multi-branch systems.
