A system and method which can complete a call to a specific Inmarsat subscriber ship. When a call arrives at a gateway switch, a test is made to determine if the called ship is in the gateway's local database. If it is, then a current region code is retrieved from the database and substituted for the dialed code for callprocessing. A call is then placed to the ship. If the call can be completed, the call is processed normally. If the call cannot be completed because the ship cannot be located in the selected region, then the call is automatically retried to each of the other regions, in a predetermined order. The local database in the gateway switch will be updated whenever a call is completed whether the call was originated or terminated at the mobile terminal.
