Abstract
The present invention relates to hotline routing of calls originating from mobile stations. The hotline routing conserves MSISDNs for valid subscribers and provides a relatively generic solution. In one example, a computer system stores in a location register a subscriber profile with an IMSI and a pseudo-MSISDN. A mobile station (which includes a SIM with the IMSI) originates a call. After translation of the pseudo-MSISDN, a serving MSC routes the call to a service activation center.
