Question about Siemens Optipoint 420 Standard Op420 Voip Ip Phone

1 Answer

We had a storm go through and now I have six Optipoint 420 Standard phones with the LAN port not working. I've reset the phone to factory settings, reapplied my configuration, and installed the software and successfully ran the limited Ping from the phone's Web diagnostics page. What can I do to fix the LAN port?

I have a hard time believing six would all fault the same way. I would first check your router/switch for problems which is common to fault on power spikes,(often fixed with a 1 minute power down) then check your phone servers connection. hope that helps you. cheers

    Thank you gurvy for your quick reply. The phones are on different POE switches, in different buildings. I did plug the computer directly into the CAT5 jack and had connectivity on a few of them so I am fairly certain it is a problem with the LAN port. The VoIP side of the phone is working fine and it can make and receive calls. I was just hoping there was diagnostic software or a component I could replace to keep from having to limit these phones to areas where there are no computers.
    Thanks again - LP

Change internal directory on optipoint 500

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).

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.
