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.
