I have a Poly CCX600 running Firmware Version 6.2.23.0202. I see all of my contacts from Outlook in A-Z order by the first name. How do I search for a contact, rather than scrolling through hundreds of contacts to get to someone whose name starts with W? There is no search bar or any search function. I only get "All Contacts". I also do not see a way to set up favorites. How does that happen?
