Feature description
In Brazil an automatic long distance collect call service called DDC is
available. The Collect Call Blocking feature enables a Meridian 1
administrator to block DDC calls on incoming Direct Inward Dialing (DID)
and Public Exchange/Central Office trunks (analog or DTI2). Under the
following conditions, the Meridian 1 sends a special answer signal to the
Central Office to indicate to the Central Office that collect calls cannot be
accepted:
• The Collect Call Blocking (CCB) package 290 is enabled
• The incoming route has CCB enabled via the CCB prompt in the Route
Data Block, and
• The call is answered by a CCB user (that is, Collect Call Blocking
Allowed Class of Service or option).
