Method for selectively routing enhanced calls
 A telecommunications network (10) includes an Originating Switching System (12.sub.1) and a Terminating Switching System (12.sub.2) linked by a plurality of trunks (20.sub.1 -20.sub.4). For each incoming call it receives, the Originating Switching System establishes a Circuit Selection Capability Indicator (CSCI) value that determines what enhancement, if any, the Originating Switching System will provide to the call. The Originating Switching System also utilizes the CSCI value to select an appropriate trunk that is compatible with a type of call enhancement, if any, to route the call to the Terminating Switching System which also enhances the call in accordance with the CSCI value. Determining the call enhancement in accordance with the CSCI value allows different types of calls which are routed on the same trunk to get different call quality enhancements, depending on the call type.
