yealink t19. How to create more than 5 groups in a local directory ???
5 groups aren't enough....

You can import remote phonebook for many groups.

If to make through the remote phonebook, then Caller ID doesn't work. number is highlighted simply.

Through the local directory contact works normally

I think you can search the incoming/outgoing caller ID by enabling "Incoming/Outgoing Call lookup".
Please refer to admin guide.
