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 Technische Universität 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.

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.

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