About-SLine
SLine Coorporation SH.P.K. was founded in 2021, but the idea started years earlier. Since 2017, we operated our own call center company and repeatedly faced the same issues: unreliable providers, poor voice quality, high prices, and frequent outages. It quickly became clear that many companies suffered from the same problems - not because of their own performance, but because their telecom partners did not support them well enough. From that experience, SLine was born: a provider that builds systems profitable for businesses themselves - not only for the provider.
Our mission is clear: deliver VoIP services that are reliable and scalable for every business in the DACH region and in other countries. Whether a small startup or a large enterprise, we ensure your communication runs smoothly and grows with you. Our vision is to become the leading VoIP provider in the DACH region while setting the standard for trust, transparency, and innovation.
At SLine, we focus on the essentials of modern business communication: SIP trunking, voice services, DID numbers, dialers, and CRMs. With these core solutions, we give our customers the tools to work efficiently, cost-effectively, and flexibly. Every service we offer is built on our promise: reliability, fair pricing, and full transparency.
Great communication starts with listening. That is why we invite you to get in touch directly. Contact us for a free consultation.
