How to connect Siemens optiPoint 500 Standard to PC via USB

The extension name and extension number are set in the system programming. Use manager 'e' and change them in the station view. If you are swapping people around and want them to keep their extension numbers and names, you should re-patch the cables feeding to the wall sockets rather than change the programming (if you can).

Hi Steven,
I have this Manual for you on this site, you may want to check the settings for that.

Possible fault in the tone ringer IC. This is normally triggered by the incoming signal before the line is switched on. So the IC takes the pulse straight from the incoming voltage , normally from the line in rectifier.
So use a meter to see with a test call for the pulsating voltage on the IC, if present then the IC is faulty. If absent check the inline signal being absent to this section.

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.

Usually changed by your Siemens system programmer.

Can be changed by the customer using Manager C software or by using an optiset E Memory Handset.
