blended identity of alpha URI and number?

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-cisconumber tag with the accompanying directory number to the SIP identity headers. The x-cisconumber 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_F3
