Choose your own softphone

If you are a user of our phone system, you have the option of a softphone.

With us, you can choose any softphone from any software developer and include it in your call team. So you are not tied to 1 brand of softphone or 1 softphone provided by your provider. This is important because it gives you the freedom to choose the softphone you like best.

The 2 most used softphones in 2023 are

The Zoiper softphone (
The Bria softphone (

You can buy these softphones directly from the manufacturers as software licences. We will provide you with the login details so that these softphones can register with us on your PBX.

Importantly, softphones have advantages but also disadvantages, especially if you install them on your mobile phone.

A softphone on a fixed computer usually works perfectly. With a headset on your computer, it has become a full phone.

This is useful if you make or receive a lot of calls, as it leaves your hands free to type. And you don't have to invest in new desk phones (just headsets).

A softphone on a mobile phone has its drawbacks.

The main disadvantage of a softphone is that it is an app on your phone. And an application closes itself or goes to sleep after a while.

From then on, you will no longer receive incoming calls. Without you noticing.

Also, a softphone on your phone uses a lot of battery. Your battery lasts much less because you have a second phone on your phone.

We do not recommend using a softphone on your mobile phone.

It is not stable and reliable, and it will drain your phone's battery.

Your business phone number exactly the way you want it !

Register your phone number with Belfabriek and you will have full control over your business phone number thanks to our handy apps and functions.

You have real-time access to the most important statistics and adjust all settings with one click. Anywhere, anytime.

The clear connections and rates are not the only reasons why entrepreneurs register their telephone number with Belfabriek. With our generous package of features, you get more features that other providers can't offer.

Equally important is the freedom and control you have thanks to our apps.

Call filter

Are there callers you would rather not allow to call a particular number, for whatever reason? You can easily block them with the call filter feature.

Call overflow handling

An enormously successful marketing campaign? Free publicity in national media? A successful Google Ads campaign? Commendable reviews on a comparison site? No problem!

Call recording

"This call may be recorded to ensure the quality of our service." Those calling a business number regularly hear a similar announcement. Chances are that these numbers are hosted by Belfabriek.

Call statistics

You have a business phone number so that your customers can reach you easily. You want to talk to more callers and serve them better. But how do you know if you are achieving your goals? Measuring is knowing.

Caller queue

There will be times when you have more callers than staff available on the phone. These types of call peaks are easily managed with call queue, a great feature available to every customer at Belfabriek.

Central Branch Phone Number

Our IVR platform can distribute hundreds of simultaneous calls across all your branches in one or more areas.

Change destination

Callers are routed to all your phones: landline, mobile, VOIP or traditional. You can change this destination whenever and as often as you like.

Direct forward

Your phone number is a virtual number. This means that every incoming call is forwarded to an extension. This can be a landline or mobile phone.

International telephony

Deliver calls domestically or to other countries? No problem!

Phone menu

Your customers would prefer to have someone on the line asap. Not every colleague knows how to answer every question. With a phone menu, you put callers through to the right person as quick as possible.

SMS sending tool

For short messages to your customers SMS are an excellent medium. But how do you send them to large groups? The SMS tool from the Belfabriek is a real godsend.

Statistics by e-mail

Your daily, weekly or monthly call statistics overview conveniently in the mail. Included with your telephone number, of course.

Text to Speech Bot ✨

Do you want a welcome message on your number? Are you not a fan of your own voice? And is hiring a professional voice actor just a bit too expensive for you?

VIP Whitelist

Do you want to grant access to your business telephone number only to a certain group of contacts? With a VIP whitelist you ensure that the lines remain free for whom your telephone number is intended.


Never miss a call when all your colleagues are busy or you are temporarily unavailable.

Welcome message

“Thank you for calling…” is usually the first thing you hear when you call a professional company.
