The end of ISDN

The major wholesalers like KPN have realised that traditional ISDN telephony is too expensive to maintain compared with an Internet VoIP alternative. ISDN will be phased out in the Netherlands by 2019.

VoIP features and savings

Internet telephony offers great call management features making it easier to run a business from anywhere while at the same time offering savings of up to 70% compared to a traditional business telephone system.

Moving to a new office

If you have outgrown you current office, simply need to move to a new location or are opening a new office, it is a good idea to rethink your telephone system. If you have two or more locations one VoIP system is enough.

Switch Provider

Many VoIP suppliers are ICT Specialists that unfortunately don't understand VoIP technology. We understand exactly how to deliver high definition sound and uncompromising reliability.

Moving your telephones to Workvoice

Four easy steps to ensure your company is always available via telephone

  1. EXPERT ADIVCE AND PROPOSAL  The first step in moving your telephones to Workvoice is to talk to us. We offer free, expert and fair advice on which features will most benefit your business. We’ll work with you to understand your needs and then make an obligation free proposal. 
  2. PLANNING  On acceptance of our proposal we will call you to let you know when the port can take place. One week before your agreed port date we will provision your telephones, set up your Internet Telephone system with your call plans and ship the phones to you.
  3. INSTALLATION AND TEST  Once you have received your phones, you can plug them in yourself, or ask your IT supplier to do this for you. It’s easy - just plug and play. If there are any issues at this stage, we provide you or your IT supplier with the necessary support to get your professional VoIP service up and running. At this stage your old telephones are still working, so your business is always available during the transition to Workvoice. Now it is just a case of waiting for your old provider to transfer your number on the agreed date.
  4. THE DAY OF NUMBER PORTING  On the day of your number port your old provider has a legal duty to port your number within 4 hours. In practise it can take only around 30 minutes and in many cases as little as 5 minutes. As your Workvoice system has already been tested it is now live and available for incoming calls on your telephone numbers.

Why Workvoice?

Six reasons why the Workvoice team at Callstera is the right choice
for your telephone needs

We are VoIP experts
Our years of specialising in Voice over Internet Protocol (VoIP or Internet Telephony) tells us that it is different to traditional telephony. With the greatest of respect to traditional IT Management, Internet Telephony has to be fully understood to be successfully introduced into a new organisation. So to make the smoothest possible transition to professional carrier-grade Internet Telephony without compromising quality of service you need VoIP specialists that understand all of the subtleties and nuances required to achieve high definition sound and uncompromising reliability.

24/7 Monitoring
We invest a lot of time and money in ensuring our service runs smoothly 24/7. Our services are continually monitored and we know within a minute if the service is not running to the high levels we expect. Our VoIP experts are standing by day and night ready to ensure those optimal levels of service are maintained. 

Not just a reseller
Unlike many of our competitors we don’t just rebadge someone else's telephony product. We have built from the ground up a modern, reliable and innovative telephony system, based on best in class open source telephony services. Importantly we are fully in control of Workvoice, so are able to offer a level of flexibility not possible if you are dependent on an offshore or rebadged service.

Great support
If you need something done, we can do it ourselves – infrastructure, software and customer care. We’re able to respond quickly, often within minutes, and always keep our services secure and up to date. When you call our hotline you don’t land in some random call centre, instead you’ll be speaking with our product experts. And – should customer care not have the answer – they work closely with our developers and designers to find the best solution for you.

Everything in the Netherlands
We work together in the same location Haarlem. Our infrastructure and servers are also all in the Netherlands. Everything is subject to the strictest of Dutch standards and laws. We are monitored by the ACM to make sure we conform to Dutch telecoms laws. This way there’s no need to worry about privacy policies and data security.

Satisfied customers
Our customers know they’re in good hands. How do we know? Although there are no minimum contract lengths with Workvoice, customers choose to stay with us for years instead of switching to a new provider. We see our customers as long term business partners. That’s how we continue to innovate and fine tune our products and services to change telephony for the better. We would be delighted to accompany you and your business in the future too.
