Open Telekom Cloud for Business Customers

Communication and collaboration using the Open Telekom Cloud

The management, expansion and updating of older telephone systems in particular is expensive and time-consuming – not to mention the limited options for further development. So it makes sense to take the next step: in addition to the simple telephone functions, a cloud-based telephone system provides numerous other functions for unified communications and collaboration (UCC). As well as reduced administration demands, the cloud operating model also impresses with its economic benefits: no investments are required, while the number of extensions and end devices used can simply be adjusted to the demands of the company at the click of a button.
