Abstract: Method and systems for providing triggerless screening services include a triggerless screening service routing node and a message processing platform. The triggerless screening service routing node identifies call setup messages that require one or more call screening services and diverts the messages to a message processing platform. The message processing platform performs at least one screening action on the call setup messages and modifies the messages to include the type and result of the screening action.
