Best business phone: delivered tomorrow!

A pre-configured and programmed Belfabriek Yealink telephone. Order today before 22:00 (CET) and you will receive it tomorrow at the (home) office.

Dial out with your Yealink VoIP phone

Yes, the Belfabriek Telephone System works with all brands and types of devices. So do you already have VoIP devices in use? Then you do not need to replace it. Unless you are a fan of the cream of the crop and want a plug & play experience. ;-) In that case the Yealink devices (exclusive with our telephone system) are highly recommended.

Why Yealink? There are a huge number of VOIP devices on the market. In all price ranges and qualities. In fact, there are so many that it is impossible for our employees to keep up with all of them. Let alone offer support. Where are the Sip / Codec / NAT settings of type A, B, C, D to Z again? Because we received a lot of questions about choosing the right device during the Corona crisis, we dived deep into it. And so we arrived at the Yealink devices. We now offer these - exclusively - preconfigured and with a 5-year warranty.

We deliver the phones pre-configured, you just need to connect them to your existing network and they register themselves.

The telephone registers via an existing Internet connection with our telephony servers and voila, you have a working telephone.

We offer you a 5-year warranty on these telephones, so that you are assured of working telephones within your organization.

Our platform is fully optimized and tuned to Yealink technology and functionalities. All functions work optimally and you can also easily manage the phone's address book through our portal.

Other Pros

Ordering and process

You can easily place your order on our website 24 hours a day, 7 days a week. Below the delivery times per product:

Phone numbers

Depending on the country and series, we can issue and activate numbers immediately or we must first complete a registration in your name with the relevant government organization.

Do you already have a number and do you want to move it to Belfabriek? This is possible and regulated by law. We can move the number to us and are happy to give you a temporary number if you want to test and configure the new devices already.

For countries abroad, you can either first place an order for a preferred number, after which an employee will contact you within 1 working day, or you can call our service desk and first discuss the options by telephone. Depending on the country, we have a number active the same working day or within a few days.

Telephone sets

If you use the Yealink devices recommended by us, we can configure them for you and send them to you. You then have a plug and play experience. Orders placed before 22:00 (CET) are delivered the next working day.


You can download softphones for your PC, Mac, iOS or Android device 24/7 to the devices of your choice.

SIP accounts

You can create and activate/deactivate these yourself 24/7 via the web interface. This way you can easily create accounts for all devices that you want to connect.

Belfabriek Apps

You can download these 24/7 in the stores or via a download link provided.

Rolling out your devices

You can learn to configure, but most people don't enjoy it much. And so we gladly take over that responsibility from our customers. Just like 'the hassle' surrounding selecting and ordering telephones. To make this possible, we have invested heavily in central configuration of our softphones and an automated distribution center for Yealink desk devices.

Hardphones are shipped preconfigured from our own warehouse. To a central location, but also, for example, to different branches or the private addresses of individual employees. Usually: ordered before 22:00 (CET), next day at the workplace of your choice! If it concerns addresses 'further away' in Europe, you will receive the devices via UPS after 2-3 working days.

Employees receive download links to pre-configured softphones, your choice for desktop and/or mobile.

We offer organizations with more than 100 users the opportunity to design the softphone environment in the house style (branded). This can be realized within a month (design, implementation and rollout). Inquire about the options!

Advantages at a glance:

  • Quick and easy rollout of new devices

  • Pre-configured and remotely manageable

  • Regular firmware updates (remote)

  • Branded environment possible from ~100 users

Your business phone number exactly the way you want it

Let our employees set up your telephone number the way you want it. You can then easily make adjustments yourself or let us do it so that you don't have to worry about it anymore.


Are there callers that, for whatever reason, you’d rather they didn’t have access to one of your numbers? Block their calls with our easy to use blacklist and keep your lines open for important calls.

Call Overflow Handling

A wildly successful marketing campaign? Free publicity in the national media? A runaway Adwords campaign? Rave reviews on a comparison site? No problem!  Even the busiest peak in calls is no problem for us.

Call recording

“This conversation may be recorded for quality assurance.” If you call service numbers, you’ll hear a message to this effect used regularly. Odds are they are hosted by Belfabriek.

Call statistics by email

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

Caller queue

There may be times when the number of simultaneous callers exceeds your available staff. You can stay on top of these peaks with a virtual queue, a handy feature available to every Belfabriek customer.

Change extension

Your service number is a virtual phone number. Calls to this number are automatically put through to your current phones. These can be landline, mobile, VOIP or traditional. You can change the destination number whenever and as often as you like.

Digital answering machine

You never have to miss another call. Not even when all of your lines are busy, the queue is too long, or you’re unable to take the call for any other reason.

Direct Call Forwarding

Your business number is a virtual phone number. This means that incoming calls are forwarded to a phone number of your choice. This can be a landline, a mobile phone, or even an offshore call center. You decide where to answer your calls.

Greeting message

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

Multiple branch phone number

Our IVR system can distribute hundreds of simultaneous calls across your nationwide network of branches.

National and international call delivery

National and international call delivery? No problem!

Phone menu

Your business partners or customers want to get an employee on the line as quickly as possible. But most employees won’t have an answer for every conceivable question. A phone menu enables callers to get the right person on the line ASAP.

Pre announcement tone

Business owners often use several numbers, each for a distinct purpose or webshop. In these cases, it’s useful to be alerted to which of your business phone numbers the call is coming in on.


The main objective of a service number or business number is to optimize the availability of your organization. You want to serve more customers and provide better service. But how do you know if you accomplish these goals? The numbers don’t lie.

Text message tool

SMS messages are a great way to communicate short texts to your customers. But how do you send an SMS message to large groups?

VIP whitelist

Do you want to restrict access to your phone number to a limited group of contacts? A VIP whitelist lets you keep your lines open for the people your number is intended for.
