Green-VoIP with snom

“Green IT“ is the hot topic in information technology – not just during the CeBIT. A sustainable and encompassing “green strategy“ does not stop at energy-saving servers, computers, and monitors, but also includes phone communications.

With snom VoIP phones you can be certain that you are also conserving energy when making calls!

In spite of the relatively low energy consumption of IP phone models, it accumulates over years and the used number of IP phones. Using the snom calculator you can easily learn by playing how big your cost-savings with snom IP phones are in comparison to other IP phone models.

Please notice: The calculator is merely meant to serve as a rough guide. The results and data upon which this calculator is based were collected to the best of our knowledge and belief. Nevertheless other data bases or calculations can result in different results. Should we become aware of statutory violations, erroneous or misleading data, etc., we will remove this link immediately.

The Research Team for Telecommunications Networks (Forschungsgruppe für Telekommunikationsnetze) at the University of applied science Frankfurt am Main (Fachhochschule Frankfurt/Main) tested the power consumption of VoIP phones produced by seven well-known manufacturers. The unequivocal result in each usage scenario – whether on standby, in call, three-party conference, of standby after call:

snom phones have the lowest power consumption in each respective class of phones.

With snom phones, enterprises benefit from VoIP technology at its highest level. snom packs multiple features for upscale business telephony into phones that are as innovative as they are functional in design. Simultaneously the use of snom phones contributes to a modern “Green IT” strategy that saves resources and lowers power costs. Contact us - we would be happy to advise you on how you can realize „Green VoIP“ with snom phones in your enterprise.
