You can use URI dialing to make calls and resolve contacts with Uniform Resource Identifiers (URI). For example, a user named Anita Perez has the following SIP URI associated with her directory number: firstname.lastname@example.org. You can use URI dialing to call Anita with her SIP URI instead of her directory number.
Users that are connected to Cisco TelePresence Video Communication Server (VCS), are only accessible using their associated URI.
Imported Contacts from Microsoft Outlook
Contacts imported from Microsoft Outlook may contain SIP URIs. For releases prior to Apple OS X Maverick Version 10.9, the Mac address book may not display some characters, for example email@example.com can display as aperezexamplecom. However, you can still search and call using these URIs.
Setup SIP URI
Before you begin
Ensure that you have configured the Address Book Plug-in for Cisco Jabber for Mac.
Select the user in your Mac address book and select Edit.
Within the phone section of the contact card, add the SIP URI for your contact.
