Leading European and South African business telephony provider Voys has strengthened its operational capacity with the takeover of Dutch telecom company Call-In-One. 

This latest integration will see Voys significantly expand its cloud telephony services for SMEs as these expand or add call centre functions. 

The large enterprise segment is already growing strongly at Voys: the acquisition of Call-In-One is set to reinforce the company’s core competence in this crucial area.


Meant To Be

Founded in 2011, Call-In-One specialised in PBX solutions for bigger multi-site or single-site businesses by providing all the benefits of a large PBX system without the upfront investment or need to house and maintain hardware on site.

Call-In-One was an early innovator in the use of IP connectivity such as broadband to provide powerful features to reduce total costs; improve productivity and enhance the image of businesses. 

Voys and Call-In-One have been working closely together for close to a decade, so the official integration is a logical evolution. Through the acquisition, Voys expands its portfolio and bolsters its ability to offer a communication solution to suit every organization.

Strategic Cooperation

The strategic partnership between Voys and Call-In-One started in 2015. “With Freedom, Voys had a wonderful cloud telephony solution for small and medium-sized companies,” says Mark Vletter, founder of Voys. “We wanted to accommodate customers who were growing or who were looking for call centre functionality. We were able to do that through the collaboration with Call-In-One.”

Voys founder Mark Vletter and Call-In-One founder Ben Hoetmer seal the deal.

Growing Portfolio

Ben Hoetmer, founder of Call-In-One, started the company in 2011. He says: “Organisations that have been customers of Call-In-One from the start still are, which indicates high levels of customer trust and happiness.” The large business market is now a strongly growing portfolio within Voys. “Over the years we have welcomed great customers, such as the Municipality of Groningen.”

Single Organisation

The acquisition of Call-In-One is not the only one Voys has accomplished  in recent years. 

“In 2020, we took over Eigennummer.nl and Voys South Africa is now a full part of the organisation,” explains Vletter. In addition, the telecom provider announced earlier this year that they will continue under the name Voys together with software company Devhouse Spindle.

“Voys has become one organisation that can offer every type and size of company a suitable cloud telephony solution. These acquisitions and mergers ensure that we can bring an ever-improving product to an ever-increasing group of customers, both in the Netherlands and abroad.”

Increased Impact

Voys is deeply committed to the positive impact the company has on global society. Says Vletter: “We are a purpose-driven organisation. Our goal is to close the digital divide in order to give more people across the planet equitable access to connectivity. This we do this with our foundation 48percent.org. As one large organisation we can now work even more intensively towards this goal.”
