Explanation:
Cisco Unified Communications Manager supports blended addressing of directory URIs and directory
numbers. When blended addressing is enabled across the network, Cisco Unified Communications
Manager inserts both the directory URI and the directory number of the sending party in outgoing
SIP Invites, or responses to SIP Invites. The destination endpoint has the option of using either the
directory URI or the directory number for its response—both will reach the same destination.
Cisco Unified Communications Manager uses the x-cisco-number tag in the SIP identity headers to
communicate a blended address. When both a directory URI and directory number are available for
the sending phone and blended addressing is enabled, Cisco Unified Communications Manager uses
the directory URI in the From fields of the SIP message and adds the x-cisco-number tag with the
accompanying directory number to the SIP identity headers. The x-cisco-number tag identifies the
directory number that is associated with the directory URI.http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/10_0_1/ccmfeat/CUCM_BK_F
