Gigaset AS690 Phone

Hello anyway....
What does the handset display during a call?

Especially when it's not there...

Thank you for the response. My phone displays the caller's number in the directory, where the registered names are indeed present. Previously, my Gigaset A415 displayed the name correctly.
Thank you, is there a solution?

A thank you is appreciated.
Mark it as resolved if your problem has been solved. I use the informal "tu" with everyone.

If the number is displayed and the name is indeed in the directory, you need to check that, in your directory, the number is in the same format as the one you receive on the screen during a call
for example, if during the call you have 0123456789 and in the directory there is 01 23 45 67 89, then it will not work.
