Abstract:
1. A method for message-based intelligent tandeming of an incoming call to an application node in telecommunication systems, the method comprising: (a) receiving an incoming call leg at a first node, the incoming call leg being directed to a called party directory number; (b) transmitting a first message to a database to determine call treatment instructions; (c) receiving a second message containing a tandem parameter; (d) when the tandem parameter does not indicate tandeming, routing the incoming call leg to the called party directory number; (e) when the tandem parameter does indicate tandeming, obtaining a routing parameter and performing digit analysis of the called party directory number; (f) when the digit analysis has been performed successfully, tandeming the incoming call leg to the application node, whereby when processing at the application node is completed the call leg is returned to the first node; and (g) when the digit analysis has not been performed successfully, providing a default mode for the incoming call leg.
