Features and Services
Operating parameters
Although designed for China, the China – Flexible Feature Codes feature can
be used in other markets.
Busy Number Redial is only available for internal calls and for trunk calls that
provide a busy signal when busy tone is given.
Busy Number Redial and Customer Call Forward are only available for
analog (500/2500 type) telephones.
Outgoing Call Barring does not apply to BRI sets.
The Reply DN for CCFW is limited to 16 digits.
OCB will only process “*” and “#” according to the active NFCR tree if the
digits are to be outpulsed on a route with OPR active (including all necessary
conditions for OPR). If they are dialed as part of an FFC, the call is allowed;
otherwise, an octothorpe will cause the call to be blocked. An “*” will be
ignored, except during digit counting. Thus, FFCs containing a “*” or an “#”
cannot be blocked by this feature.
OCB will not prevent calls from terminating when there are too few dialed
digits to traverse the full NCFR tree (for example, if the active tree is set up
to bar 2001, but a DN of 200 exists, calls to 200 will be allowed with no error
message).
The maximum number of digits that will be processed by OCB is 32. If the
call is not allowed or denied by that point, the call is barred.
OCB can bar feature access codes such as Special Prefix (SPRE) codes and
numeric FFCs. It will not bar the digits dialed after a feature access code.
