Outgoing public calls routing
Outgoing public calls from within the system typically have the routes set to Public. Refer to
“Configuring call routing” on page 331 . The NPI/TON gets sent as Unknown/Unknown. The
public called number length is based on the Public DN lengths table in the Public networks dialing
plan.
MCDN trunks also allow public call types when tandeming calls from another system on the
private network. Some of these systems use specific call types that the Business Communications
Manager needs to recognize to pass on correctly. Also refer to
“Using the MCDN access codes
(tandem calls)” on page 327 .
