Abstract

A mechanism for rejecting specific types of calls in a network including collect calls and telemarketing calls. Calls are tagged to indicate the type of call, this tag being recognizable at the terminating end of the network allowing automatic rejection of the call on a subscription basis. In one embodiment, an OLI parameter is utilized to tag the call. In another embodiment, another parameter such as Optional Forward Call Indicator is utilized. An end office serving the subscriber may automatically reject the call, or may pass on the call to a PBX serving multiple subscribers. The PBX may automatically reject all calls of a particular type, or may allow calls depending on the subscriber being called.
