Calling Card Information
The importance of a calling card rests in the different dialing procedures required by the various calling
cards. An application provides TAPI with the information it needs to display a
dialog box, from which the user can choose a calling card. (The calling card
numbered 0 means "use the default dialing rules for the country you are in.") The
routine returns, among other information, the user's location (country and area
code), the number of calling cards registered for this user in the registry, and
the preferred calling card for that location. This calling card information is
applied by the lineTranslateAddress function and does not happen automatically through lineMakeCall.
Typically, an application would prepare a menu choice for the user, such as
whether to make a call with the default carrier, to override the default carrier
and use a given calling code, or simply to use another specific dialing
sequence.
