      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 them all. 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 the right device choice 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 23:59 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 applies: ordered before 23:59, 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



      With the user-friendly and further developed web interface you can easily manage important settings and contacts within the system. Do you not want to have to worry about it yourself? Call us for free or email our support staff, they will be happy to make the changes for you.

      Address book

      The address book has been a much requested feature over the years, which you don't often come across elsewhere. Within the address book you can easily enter your internal and external contacts with the corresponding telephone numbers and synchronize them to all your devices that are in use within your organization. It works with both hardphones and softphones, ensuring that everyone has the most important phone numbers at their fingertips.


      If you wish to make use of this, you can set the availability of employees. With telephone exchanges, this is not actually taken into account (they only have to call forward), but what is actually one of the most useful functions within a telephone system: who is available and available to answer the telephone? By simply setting an availability schedule, which you can also easily adjust, our platform knows exactly to whom a call can be forwarded at what time.


      Online statistics of all your incoming calls with a clear interface. What are the busiest days of the week, the busiest times in a day?How many calls does a branch receive? What is the average call duration?

      The owner/entrepreneur or call center manager is presented with the most important data in a handy dashboard. And if you want to know more, you can easily download all data to your computer.

      Contacts and departments

      Do you have multiple contacts who manage telephony within your organization? Do you want to assign certain numbers to another office or departments? Whether the invoice has been split or provided with a certain characteristic. You can easily pass on all of your information to our administration.

      Meet your softphone

      Are you a fanatic Skyper? Or do you call with another software package? Then you already know what a softphone is: a program with which you can make calls on the computer. Just like on your laptop, mobile phone or tablet. If Windows, Linux, Android or iOS feel at home there, chances are a softphone will work. But which one do you choose?

      If you are using our Phone System, the Belfabriek softphone is the best option. Especially since our softphone works seamlessly with the Phone System and all important settings are preconfigured. A real plug & call solution, because you only have to enter your password or scan a QR code (new feature!) to get 'in the air'. It couldn't be easier! Also handy: the address book works in the softphone environment.

      To combine? No problem! The Belfabriek Telephone System works with softphones, but also with a combination of softphones, regular telephones and mobile devices. You determine the ideal setup yourself! What does employee X or Y need? You indicate it. We take care of the smooth rollout. Good to know: the softphone is part of the Belfabriek Telephone System. So there are no costs involved.

      • The five biggest benefits

      • Regular new updates

      • Pre-configured solution

      • Easy to set up with a QR code

      • Access to central address book

      100 workplaces? Branding of the softphone is possible!

      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 in no problem for us.

      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 CallFactory 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

      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?
