VOIP Telephony: What is it?

VOIP stands for Voice Over IP. If you're familiar with computer jargon, you'll understand that this phone system uses an internet connection, hence the "IP" since it uses an IP address to transmit audio.

This system allows you to make calls like any traditional telephone, the only difference being that it goes through the internet instead of the public switched telephone network. VOIP phones can be hardware-based, so they look like the phones you normally use; or software-based. Software phones are sometimes also called “softphones” or “webphones” because they are based on a web application and can be used on any computer, tablet, or even smartphone.

VOIP Telephony: The Features

VOIP phones of course offer the basic features of any phone: making and receiving calls, receiving messages, accessing your contact list, etc. Softphones also often allow you to benefit from more sophisticated features such as video conferencing or even instant messaging.
Some VOIP phone services, such as 3CX , the VOIP technology we use, also allow integrations with Microsoft 365 and Teams but also with your CRM, thus simplifying your work and centralizing customer data.

The benefits for your business

  • More adaptable because it doesn't rely on a physical cable network like traditional telephones. This allows you to adapt the service to your needs as you go along, without any complex procedures. For example, if your team expands, it's very easy to add a line; just ask your provider, and the addition will be done in the blink of an eye.
  • More flexible because if you opt for the web-based version, you can take your phone with you everywhere and therefore answer calls remotely, without being at your desk. This advantage is even more convincing if your teams work in hybrid mode or are completely remote!
  • More cost-effective , often cheaper initially because it eliminates the need for a large number of individual phone lines. It also allows you to make international calls without paying extras related to the traditional telephone network.
  • More scalable , in fact, VOIP telephony services are constantly updated to keep up with trends and technological advancements. If a new communication technology emerges, it is very likely that your service provider will integrate it into its offering. This is the case, for example, with 3CX, which now offers a live chat option to integrate into your website!

In summary

If you're still hesitant about switching to VOIP telephony, you should have no more doubts: adaptability, flexibility, cost-effectiveness, and scalability are considerable advantages for your business. And they're even more compelling when you consider the hybrid work environment many companies are experiencing today! So what are you waiting for?
