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.

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 queues

There may be times when you have more callers than staff available on the phone. These call peaks are easily handled by the call queues, a great feature for every Belfabriek customer.

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 by email

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

Change device extension

Calls to your virtual telephone number are automatically put through to your current phones. These can be landline, mobile or VoIP. You can change the destination number whenever and as often as you like.

Digital answering machine

You never have to miss a call, even if all your colleagues are busy, the queue is too long or you are unable to pick up for other reasons.

Direct callforwarding

Your company number is a virtual number. This means that every incoming call is redirected to another telephone. This can be every landline or mobile phone.


Are there callers that you would rather not give access to a certain number ? You can easily block them with the call filter function. This way you keep your phones free for the callers that are important.

International telephony

Delivering telephone calls nationally or in other countries? No problem!

Multiple branch phone number

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

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 choice menu, you put callers through to the right person as quick as possible.

Pre-announcement tone

Many entrepreneurs have multiple numbers for multiple purposes or web shops. In such a case, it is useful to know at the beginning of a conversation which telephone number is being called!


You choose a telephone number mainly to optimise the accessibility of your company. You want to answer more callers and be of better service to them. But how do you know whether you are achieving the intended goals? Our statistics.

Text message 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.

Text to Speech speechbot

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 list

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.

Virtual Callcenter

With a virtual call centre you make sure that callers are distributed fairly and evenly among available colleagues, at home, in the office or anywhere else.


Flexible switching of end destinations via your own website using a webhook

Welcome message

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