Tiny calling card application

The tiny calling card is a stripped-down Calling Card application without speech. It suits callers who always call from a registered number and only need a second dial tone, for example from a fixed line in a shop.

  1. The call reaches a connection whose CLD Translation Rule rewrites the number to cctiny.
  2. The caller must have a trusted number linked to a card; there is no card entry.
  3. The application plays a dial tone instead of a prompt and collects the destination.
  4. It places one call and hangs up afterwards, whether the call succeeded or not.
  1. Register each caller’s number as a trusted number of their card account.
  2. Add a Connection with Destination set to the IVR service of the switch and CLD Translation Rule s/.*/cctiny/.
  3. Route the tiny calling card access number to that connection.
Option Default Meaning
Minimum call duration 10 Below this computed duration the call is refused for insufficient funds
Maximum call duration 3600 Longest call, in seconds
Outgoing SIP host 127.0.0.1:5060 Host and port outbound calls are sent to
Keep CLI false Present the caller’s number instead of the card number

These options are stored on the switch for the tiny application and are changed by support.
