Carrier Call AG

Company

Who we are

We are Carrier Call, Europe’s most powerful provider of ICT automation and digitalization solutions in the fields of carrier interconnection, wholesale trading, traffic management, switch provisioning, mediation, billing and reliable fraud detection and prevention.

Our XCarrier platform and application modules enable telecom carriers to generate positive margins in a highly volatile carrier market environment. Deploying the XCarrier platform puts our customers’ core switching infrastructures and interconnection links to other wholesale providers to optimum use. Our solutions and the associated services have been impressing our customers for years due to their modular structure, flexible configuration management and incomparably efficient operation.

With configurable adaptations, XCarrier can be quickly introduced and deployed in other industries, such as the utilities sector (e.g. electricity, gas or water). Our solutions process the highest volumes of master and transaction data in record times.

Our Mission

We ensure that wholesale carriers can digitally determine, optimize and securely manage their business with our application and development platform XCarrier.

This enables them to secure and optimize revenue streams and margins in the highly dynamic telecom market. In addition to the XCarrier applications and customer-specific applications, our professional services and the associated system integration complete the Carrier Call offering.

Our Philosophy

We don’t compromise on convincing results. That’s why we consistently tread our own path and deliver above-average performance.

We pursue our independent goals.

We want to be the first choice for telecom carrier customers looking for a seamless, profitable and fully automated digital business.

We aim to deliver outstanding software solutions and services that enable the greatest possible efficiency, as well as operational and commercial security.

We attach a great deal of importance to nurturing a close and trusting cooperative relationship with our customers and promoting open and transparent dialog. Our long-standing customer relationships are testament to our strong commitment to providing innovative, flexible solutions in a timely and cost-effective manner.

We focus exclusively on what our customers need. We are passionate about providing the best service for each and every customer and supporting them so that they can position themselves as leaders on the market.

We deliver and operate what we promise: high quality, on time and on budget. Simply Swiss precision!

Our Team

Our team boasts impressive, internationally known and extremely experienced individuals. The company is divided between software development, consulting and application engineering and obligatory business administration.

Across all our departments, our staff maintain a customer-centric outlook so that we can provide dedicated personal service to our customers and teams alike.
We only procure external services from external partner companies where necessary – when doing so is more efficient and makes sense.

Facts and Figures

We’re entrepreneurs. That means we have been constantly keeping busy, making decisions and purposefully tackling outstanding issues since 2003.

Carrier Call AG is a privately held joint stock corporation under Swiss law. The company was established by Martin Christen and Markus Wehinger as a limited liability company (GmbH) and converted to a joint stock company (Ltd) in 2019.

We are a completely independent entity, both from a technological and a commercial standpoint. Freedom of choice is and will remain a key issue for us. We’ve been managing the company as entrepreneurs since it was established, ensuring that customers are given the long-term guarantee that both our organization and our solutions will develop sustainably in the long term.
