Deutsche Telefon Standard AG: Your specialist for professional SIP Communication

Deutsche Telefon Standard AG is a specialist in professional SIP communication and is one of the leading suppliers of net­­work telecommunication systems. With its CentrexX SIP telecoms system, the company offers one of the latest and high-performance central telephone systems (IP-Centrex) from the cloud. This makes it a genuine alternative to “outdated” ISDN technology – regardless of company size. In addition, several thousand companies use the second product by SIP specialist Deutsche Telefon – its SIP telecommunication system interface (SIP Trunk). In the process, the client benefits from an “IP interface” which makes it possible to use its own (IP-cap­able) telephone system on an IP basis while simultaneously benefiting from Deutsche Telefon’s low calling prices.

Along with innovative IP technology, Deutsche Telefon also offers all desired services. Over 600 sales and service partners are available throughout Germany to install end devices and routers and check internet connections. Deutsche Telefon thus offers its clients first-class service quality, due not least to a special feature: every day from 8:00 – 6.00 pm, our clients do not speak with a call centre but directly with the committed service employees of Deutsche Telefon.
