ABSTRACT:
Methods, systems, and products are disclosed that provide disposable numbers for a conference service. A disposable number is assigned to a conference bridge that is only activated for a defined period of time, after which the disposable number is disposed and deactivated. A call is received to the disposable number, and the call is routed to the conference bridge. A database is queried that associates the disposable number to a subscriber's number. Subscriber information is retrieved that describes when a conference bridge subscription is active. If the conference bridge subscription is active, then a caller is connected to the conference bridge. If the conference bridge subscription is inactive, then the caller is prompted to pay for a conference service.
