<p class=MsoNormal style='margin-left:.5in'>Cisco Unified Communications
Manager (Cisco Unified CM) interprets calling name information (for purposes of
name display on IP phones registered with Unified CM only in the Display IE of
the H.323 Setup and Notify messages. Name display information delivered in an
H.323 Facility message is not interpreted by Cisco Unified CM. Some ISDN switch
types (for example, NI2) send a "name-to-follow" indication in the
Q.931 Setup message and deliver the calling name subsequently in the Facility
IE of a Q.931 Facility message. When a Cisco IOS gateway is connected to such
an ISDN switch and interoperating with Cisco Unified CM by using the H.323
protocol, Cisco Unified CM is unable to display calling names on IP phones.<o:p></o:p></p>
