Explanation:
Cisco Unified Communications Manager supports dialing using directory URIs for call addressing.
Directory URIs look like email addresses and follow the username@host format where the host
portion is an IPv4 address or a fully qualified domain name. A directory URI is a uniform resource
identifier, a string of characters that can be used to identify a directory number. If that directory
number is assigned to a phone, Cisco Unified Communications Manager can route calls to that
phone using the directory URI. URI dialing is available for SIP and SCCP endpoints that support
directory URIs.
