calling name support for call manager express using facility IE
Release-note: Call manager express needs to support the calling name functionality when using when the calling name is received in the form of Facility IE.
Calling name can be displayed if it is sent in SETUP or if as DISPLAY IE (these will need to be configured by your PRI provider on their switch and might require a isdn switchtype
change).
I am not clear if the fix is 12.4(x).
