ONN blocking state Suppression bit,
Service code Set the Outgoing Name and Number (ONN) Blocking.
When you activate ONN, a user can press FEATURE 819 to block the
outgoing name and number on a per call basis.
Suppression bit: the system flags the call to the Central Office (CO) so
that the name and number is not sent to the person you call.
Service code: VSC digits are dialed out before the called number to
activate ONN at the central office. These codes are supplied by your
service provider for the lines. Refer to
“Configuring ONN blocking service
codes” on page 487 . PRI lines have only one code, so do not require
specific configuration.
Programming note : Ensure that all telephones that have this feature
available are assigned valid OLI numbers. Refer to “Assigning line access”
on page 406 .
