Lost the option to call contacts by name after PSTN upgrade

Hi,

yesterday our company added the option to call people on regular phone numbers in Teams, my problem is that I can no longer enter names where I was able to, instead I now only can enter phone numbers, and the old functionality seems to be missing.

Here are two screenshots showing the issue:

where do I have to click now, to be able to recreate the situation in the first screenshot?

Cheers
