This is a SIP telephone. Special functions may be provided by the SIP provider.

I understand that you assume a power supply is included when you buy a phone. However, Unify only offers this as an option. It is not listed in the scope of delivery. Our customer service can also be contacted at any time before purchase if there are any uncertainties. I will ask whether a note can be made on the product page in this case. According to Unify you can find the suitable power supply for Switzerland here (incl. 1.8m cable): Unify Sip OpenStage/OptiPoint power supply CH
