SOURCE: Can Siemens optiPoint 500 phone be used at home

An "Optipoint 500" phone can not be used at home!
It is a digital phone, specifically designed for Siemens digital phone systems. Do not plug it in at home. That could damage the phone or may knock your phone line off.

However you can use a "Optipoint 500 IP" phone at home for voice over IP calls. But this would be connected into your broadband router and would connect via the web to your companys Siemens phone system.
