sipgate

sipgate is a German Voice over IP (VoIP) and business communication provider founded in 2004 in Dusseldorf, Germany. As one of the pioneers of internet telephony in Germany, sipgate was the first company to offer free VoIP phone numbers to German consumers. Over the past two decades, the company has grown from a simple VoIP service into a comprehensive business communication platform serving hundreds of thousands of customers across Germany and Europe.

The platform offers VoIP telephony with virtual phone numbers, team messaging, video conferencing, fax services, IVR (Interactive Voice Response) menus, intelligent call routing, and a developer-friendly API for integrating telephony into custom applications. sipgate provides both a consumer product (sipgate basic) and enterprise solutions (sipgate team) with features like call queues, parallel ringing, voicemail-to-email, and call analytics. The company has also developed clinq, an AI-powered CRM integration that automatically logs and transcribes calls.

sipgate is headquartered in Dusseldorf with all infrastructure and data processing located exclusively in German data centers. With over 200 employees, the company is one of the largest independent telecommunications providers in Germany. sipgate has built a reputation for technical innovation and an agile company culture, frequently cited as one of the best employers in the German tech industry. For European businesses looking for a GDPR-compliant alternative to US-based communication platforms like RingCentral and Twilio, sipgate offers a mature, feature-rich solution backed by nearly two decades of operational experience.
