摘要：This invention relates to methods and apparatus for the delivery of enhancedtelephony services for calls received on local telephone exchange switches. The inventionemploys an intercept node which intercepts number portability query messages andascertains whether enhanced telephony services should be applied to a call with

reference to an enhanced telephony service user database. If enhanced telephonyservices are to be applied to the call, the call is routed to a node capable of applyingenhanced telephony services, otherwise the call is forwarded on to a number portabilityprocessing node. Enhanced telephony services may thus be provided in relation to callsreceived at local telephone exchange switches which do not themselves supportidentification of enhanced telephony service users and associated triggering to initiatethe provision of enhanced telephony services, but which do generally support a numberportability mechanism.
