I have a really strange problem that should not be Cisco-related, but it seems it can be.
I have a Cisco SPA122 ATA box for my fixed telephones connected to VoIP. I used to have wireless Panasonic handsets and everything worked fine. Then I upgraded to a 3 handset kit with Gigaset C430 phones, and now the Caller ID is not showing. It says "External" on the display. I have been searching the net everywhere to see if it is a Gigaset setting, but it's not. It should just work.
I have updated my SPA122 with the latest firmware and tried some settings without any luck.
Is it possible that someone here could give me a clue what's going wrong?
