Abstract

When one party (25) to a call or connection request invokes a telecommunications service, a platform (30) monitors that request and determines whether the other parties (25) also subscribe to that service. If any party to the call does not subscribe, then the platform makes an offer of that service to each non-subscribed service. In this way, non-subscribed parties may obtain telecommunications services in a “point-of-sale” manner.
