Introducing the enterprise cloud telephony solution

Cloud telephony, or IP telephony, relies on the Internet to manage calls. Unlike traditional switchboards (PBXs), it requires no on-site physical equipment such as fixed lines or telephone exchanges.

What changes with cloud telephony :

  • Quick and easy installation
    No need for technicians or complex equipment. One account, one Internet connection and you’re ready to go.
  • No cumbersome hardware
    Everything happens online: calls, transfers, voice messages. Even remotely.
  • Reduced costs
    Less installation, maintenance or landline costs. And often, more flexible and less expensive offers.
  • Total flexibility
    Teams can call from a computer, smartphone or tablet, wherever they are. Perfect for telecommuting, field teams or multi-site offices.
  • Better call management
    Online interface, real-time supervision, intelligent redirections, personalized greetings… everything becomes easier to manage.

Key features of this telephony system for businesses

Enterprise cloud telephony solutions don’t just replace traditional lines. They deliver real operational benefits, thanks to advanced functionalities. Here are the most important ones to know.

HD call quality and predictive dialer

  • High-definition sound
    No more crackling or choppy voices. With dedicated voice bandwidth, call quality is as clear as a videoconference.
  • Enhanced customer experience
    A clear voice builds trust. A smooth call means a customer who understands better… and stays longer.
  • Predictive dialer
    The predictive dialer automatically dials a string of numbers and connects the call only when a human picks up. Result:
    • less downtime for agents,
    • more calls handled per hour,
    • improved call center productivity.

Case in point: a call center with 10 agents can save up to 1 hour of useful time per day thanks to the dialer.

CRM integration and call recording

  • Native connection with CRMs (Salesforce, HubSpot, Zoho, etc.)
    • Customer file opens automatically with each call
    • Centralized interaction history
    • Less manual input = more time to talk
  • Call recording
      • Ideal for sales coaching or customer support
      • Enables analysis of real-life conversations
      • Useful in the event of a dispute or quality audit

Here’s a concrete example: a manager can listen in on a new salesperson’s calls and give him or her targeted feedback 30 minutes after the customer exchange.

Security, encryption and RGPD compliance

  • Call encryption (VoIP/TLS) and secure cloud storage
    Communications are protected against eavesdropping or data leakage. This is essential for sensitive exchanges.
  • Servers hosted in Europe
    This ensures that data remains under European jurisdiction, a key point for compliance.
  • Integrated RGPD compliance
    • Manage access rights to recordings
    • Automatic data deletion after a set time
    • Vocal or written consent integrated into the process

Case in point: a company can set up an introductory message that informs the caller that the conversation will be recorded for quality purposes, as required by the RGPD.

These features are not gadgets. They transform the way teams work, exchange and progress.

5 steps to deploying a cloud telephony solution

Switching to cloud telephony doesn’t happen overnight. But with a clear method, the process can be smooth, fast and profitable. Here are the 5 key steps to a successful transition.

A 5-step path with icons for each phase: magnifying glass (assessment), technical plan (preparation), computer with headset (deployment), speech bubble (training), rising graph (follow-up).

1 – Needs assessment and solution selection

First of all, you need to take stock of your uses:

  • How many users? Which services?
  • Incoming, outgoing, international calls?
  • Need mobility? Telecommuting? CRM integration?

Objective: choose the right solution, neither too light nor too large.

Tip: involve your field teams (sales, support, IT) right from the start. They know what’s holding you back today… and what you need to improve tomorrow.

2 – Planning and technical preparation

Once the solution has been chosen, it’s time to prepare:

  • Check the quality of your Internet connection (priority #1)
  • Set aside migration slots to avoid blackouts
  • Portability of existing numbers
  • Ensure that equipment (headsets, computers) is compatible

Tip: ask your supplier for a technical audit to avoid unpleasant surprises.

3 – Deployment and configuration

This is the stage where everything settles down:

  • Creating user accounts
  • Set up queues, greetings, schedules, transfers…
  • Test internal and external calls
  • Portability of old numbers

Tip: start with a small pilot group to test the configuration before a global roll-out.

4 – Training and support

A good tool is useless if nobody knows how to use it.

  • Short, targeted training sessions (10 to 30 minutes)
  • Clear documentation or video tutorials
  • Individual coaching for advanced functions
  • Support available to answer questions

For example, Kavkom offers turnkey deployment, with easy start-up, customized training and responsive human support. The result: a smooth transition, even for non-technical teams.

5 – Ongoing monitoring and optimization

Once in place, further adjustments are required:

  • Analysis of call statistics
  • Listening to recordings to improve scripts
  • Add or remove users as the team grows
  • Update welcome scenarios

Tip: schedule a 30-minute monthly review of telephone KPIs.

A successful transition to cloud telephony is a mix of the right tool, the right timing… and the right support.
With a provider like Kavkom, who combines simplicity, responsiveness and expertise, you can accelerate your return on investment while streamlining your internal and external communications.

FAQ – Frequently asked questions

What is the definition of IP telephony?

Telephony over IP (or VoIP for Voice over IP) enables calls to be made via the Internet, without using traditional telephone networks. It transforms voice into digital data. The result: more flexible, cheaper phone calls, accessible from any connected device.

What are the disadvantages of VoIP?

VoIP depends on the quality of the Internet connection. Low bandwidth can lead to outages or poor audio quality. In the event of a network outage, telephony is also affected. Good network configuration is therefore essential to guarantee a smooth experience.

How much does it cost to set up this type of communication?

Costs vary according to provider and options, but it’s still much more affordable than a conventional phone system. With Kavkom, optimize your communication from just €8 per user per month.

Conclusion

Adopting a cloud telephony solution is much more than a technical upgrade. It’s a change in the way you manage customer relations, pilot teams and ensure continuity of communications, wherever your employees are. With simple installation, impeccable call quality, tools connected to your CRM and full RGPD compliance, this technology meets the needs of modern businesses, large and small.

The benefits are tangible: reduced costs, increased productivity, better follow-up, and above all, a rapid return on investment. In a context where every call can make a difference, cloud telephony becomes a real strategic lever.
