You can allow Cisco Jabber to search for people from your Mac contacts list so you'll be able to contact them easily directly from Jabber. When you search for someone in Jabber, the search results includes people from your Mac contacts list. If you receive a call from a local contact, Jabber matches that number to people in your Mac contact list.
Select the General tab.
In the Contacts section, select Integrate local Mac Contacts with your Cisco Jabber contacts.
Restart your client to see the contacts.
