SPA400 PSTN Anonymous Caller ID

Hello All,

I have an installation with a SPA400+SPA9000 and phones 3x SPA942 and 1 x SPA921. Country is Czech Republic.

Incoming  calls shows "Anonymous" instead of showing the caller id. I follow some  instructions, I have seen, in a documentation that talks about that,  but still does not work.

I have set up the following configuration on the SPA400 for Czech Republic.

Receive Gain:0

Impedance: 270+(750||150nF)

Tip/Ring Voltage: 3.5 V

Operational Loop Current Min: 10 mA

On-hook Speed: 3 ms

DC Current Limiting: Enable

Caller ID Method 'European (FSK)'

Do you have any idea what it could be changed in the config?

Thank you for your HELP.

Best Regards

                         Pavel
