SIP-telephony by TENIOS

Cloud business telephony – without hardware / software costs and innovative over all-IP.

SIP-telephony replaces and supplements the conventional business telephone via analogue or ISDN connections. In the future, you do not need your own telephone system or cost-intensive network technology. A conventional broadband internet connection is completely sufficient.
You can set-up new extensions and employees online via our web portal. Completely flexible, you can at any time add new connections or cancel unneeded ones. According to the "pay-as-you-go" model, you pay only for the number you actually need, without maintenance costs and long contract terms. SIP telephony is not only particularly favorable, but also easy and intuitive to use and around the clock. You pay only 5.00 € per phone number and 1 cent per minute (Germany landline).

Business sip-telephony can be easily and conveniently set up on the computer itself - without a technician or special expertise. All you need is a SIP-enabled phone such as SNOM or a so-called SIP softphone such as Zoiper or x-lite. You simply enter your SIP account data into the SIP telephone or softphone and you can start with the business telephony of tomorrow.
