A pre-configured Yealink phone: plug & call

Dial out with your Yealink VoIP phone

The Belfabriek phone system works with all brands and types of devices. So do you already have VoIP devices or cell phones in use? Then you don't need to replace them. Unless you want the latest VoIP phones. In that case the Yealink phones are highly recommended.
Why Yealink?
There are a huge number of VoIP phones on the market. In all price ranges and qualities. There are so many that it is impossible for us to keep track of them all. Let alone to provide support for them. Where are the Sip / Codec / NAT settings of type A, B, C, D to Z again? Because we received a lot of questions during the Corona crisis about the right choice of device, we dug deep into this. And that's how we came up with the Yealink devices. We now offer them to you pre-configured 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 place your order on our website 24 hours a day, 7 days a week !

Telephone numbers

Depending on the country and range, we can issue and activate numbers directly or we first need to complete a registration on your company name with the relevant government organization.


If you use our recommended Yealink phones we can pre-configure them. You then have a plug and play experience. Ordered before 22.00 hours, delivered the next working day!

SIP accounts

You can easily create these yourself via the web interface. So you can easily create accounts for all devices you want to connect.

Deployment of your devices

You can learn how to configure, but most people don't take much pleasure in it.

So we are happy to take that responsibility away from our customers. Just like the 'hassle' of selecting and ordering telephones. To make that possible, we have invested heavily in the central configuration of our softphones and an automated distribution center for Yealink desk phones.

Hardphones are shipped pre-configured from our own warehouse. To a central location, but also, for example, to various branches or the private addresses of individual employees. The rule is usually: ordered before 22:00, delivered the next day to the workplace of your choice! If it concerns addresses "further afield" in Europe, then you will receive the devices after 2-3 working days via UPS.

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

Organizations with more than 100 users are offered the opportunity to create the softphone environment in their corporate identity (branded). This can be done within one month (design, implementation and rollout). Ask for the options!

Benefits at a glance:

Fast and easy deployment of new devices
Pre-configured and can be managed remotely
Regular firmware updates (remote)
Branded environment possible from ~100 users

Your business phone number exactly the way you want it

Let us set up your phone number exactly the way you want it! You can then easily make changes yourself or let us do it so 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.
