Caller-id does not work for incoming calls

Not all adapters support Danish caller-id. Cisco, Sipura and Linksys do, whereas old Grandstream and Vigor and others don't.

If you have a Cisco, Sipura or Linksys adapater where caller-id is not working, your adapter is set up incorrectly in connection with. "Caller ID method". See the setup guide for help.
