"The cloud is our DNA and IP is in our blood."

Back in 2005, toplink already sold the first cloud-based telephone systems as VoIP products, developed the SIP trunk as an interface and launched the "myTelco" cloud conferencing service in 2010.

Today, toplink stands for the cloud-based digital workplace.
