A feature that enables the universal personal telecommunications (UPT) user to register for outgoing calls from the current terminal address to allow outgoing calls to be made from that terminal address. When registered, upon accessing the UPT facilities, all outgoing UPT calls can be made from that terminal address for the duration specified by the UPT user (duration may also be specified in terms of number of outgoing UPT calls,) or until a specified de-registration time. Outgoing UPT calls will be charged to the UPT subscriber. Normally, the UPT user will not have to carry out any further authentication procedures in order to make outgoing calls. However, optionally, a simplified authentication procedure may be used. A UPT user may register for outgoing calls to several terminal addresses simultaneously, but at any time only one UPT user/number may be registered for outgoing calls at the same terminal address. The UPT user may also explicitly de-register outgoing calls.
