When a user dials the Flexible Feature Code defined for the CPPO feature
and if CPPO is not provisioned on the outgoing trunk route, the call proceeds
without carrying the Privacy Override Indicator.
The CPPO feature does not affect whether or not the Calling Party Number
and Name information is displayed for internal calls within the system, even
if the originator requests CPPO.
All incoming non-ISDN calls with the Privacy Override Indicator terminate
on the system. If the Privacy Override Indicator is not defined in the Flexible
Feature Code for CPPO, an overflow tone (unrecognized digits) is provided
to the user.
If the Stored Number Redial (SNR)/Last Number Redial (LNR) feature is
used by the originator of a CPPO call to store the dialed digits, the CPPO
Flexible Feature Code is stored against the SNR/LNR database. If the user
removes that CPPO Flexible Feature Code and then the SNR/LNR feature
is used to re-initiate the call, overflow tone is returned to the user.
ISDN implementation for this feature includes DMS100/250, SL-100, AT&T4,
AT&T5, TR-1268 (NI-2), Meridian Customer Defined Network (MCDN)
Private Networks, EuroISDN, QSIG, and BRI trunks.

AXE10-CO Connectivity (Sweden), French Numeris CO Connectivity, Japan
D70 CO Connectivity, Swissnet 2 CO Connectivity, SYS-12 CO Connectivity,

The CPPO feature supports the following North American connectivity:
DMS100/250, S1100, Lucent #4 ESS (ESS4), Lucent #5 EES (ESS5), and
