TELES AG Informationstechnologien is a provider of equipment and services to fixed, fixed-mobile convergence, and Next Generation Networking (NGN) service providers.

The company was founded in 1983 as TELES GmbH by Professor Dr.-Ing. Sigram Schindler in close cooperation with the Technical University of Berlin. Professor Schindler lectured in telecommunications at the university until 1998. In 1997, he was voted High-Tech Manager of the Year by Manager Magazine in Germany.[1]

Active in VoIP technology development since 1996, the company's main development and operational focus lies in the areas of IMS and NGN.

TELES supplies service providers with complete Class 4 and Class 5 NGN Softswitch. TELES NGN is a standard based, scalable architecture aimed at minimizing integration time and allowing quick deployment. It includes hosted voice functionality which enables residential VoIP services, hosted PBX (IP Centrex) services, Fixed-Mobile-Convergence, IP Trunking, and additional value added applications. Classical NGN/PSTN applications like Wholesale, Long Distance, and NGN backbone services are also available with this.[2]

The TELES product portfolio also includes VoIP gateways and mobile gateways for GSM, CDMA, and UMTS networks.[3]
