Our customers benefit from our nationwide presence: with our comprehensive "on site" service we are close to you in the shortest possible time. In addition, we can support you "remotely" at any time.

In addition to our service strength, Ostertag DeTeWe customers benefit from a network with lasting added value and integrated solutions for process optimization. Because as a system integrator, we are manufacturer-independent and continue to offer our own OD-Cloud development — a cloud solution "Made in Germany" -, managed services, a carrier and provider service — our so-called DeTeWe.net solution — and Unified Communications & Collaboration (UCC) solutions.
