Use case
: Direct Dial-In (DDI) (aka Direct Inward Dialling DID), where a series of public phone
numbers are routed directly to predefined intercom stations. When an outgoing call is made
from an intercom station, one can manipulate the source of the caller (Caller ID) to be the
public phone number instead of the intercom station number.
