AUXILLARY COMMUNICATION SERVICE ROUTING

摘要

A system and method for routing a call through the PSTN to an auxiliary communications services mailbox (40), such as voice mail, of a mobile subscriber (30). The call is received in the nearest exchange (80) and routed to the exchange where the mobile subscriber is located (50). If the mobile subscriber, for example, does not answer, a voice mail number is used to route the call to the exchange (90) where the voice mailbox (40) is located.
