ABSTRACT:
A method and apparatus for real-time insertion of services into an IP telephony call session are disclosed. A client initiates a service request message to a second server. The service request message includes the client identity and a requested service available from a second server. The first server determines if the client is authorized to use the requested service. If the client is authorized to use the requested service, the second server delivers the requested service to the client.
