We are Summa

We believe in communications that add up.

Summa is a software company that designs and develops innovative communications solutions and platforms for service providers, telco’s, hosting providers or any organization looking to add communications services to their portfolio. Communications can no longer be seen separately, but should be integrated into other solutions; Summa focuses on creating SaaS services based on unified communications and WebRTC. We offer innovative solutions that ensure the right fit for every deployment and context, and enable customers to work more efficiently and smarter from any location.

Summa evolved from the 12-year-established Dutch and German cloud service voice provider Voiceworks.

With our joint venture Summa Networks we are also active in the development of telecom software. Check out summanetworks.com for more details.
