Abstract

A radio communication system with on/off premise registration is provided. When a radio is registered with the system, incoming calls for the radio are directed to the radio via the system. When the radio is registered as off the system information is transmitted to the radio as via a wide area system. A voice mailbox is provided for storing messages when the radio is unavailable.

means for connecting the radio with the call if the radio is registered on the site system,

means for transmitting information to the radio via the wide area system if the radio is registered off the site system and the radio has registered to have information forwarded to a wide area system; and

voice storage means for storing messages when the radio is not registered on the site system and is registered to have messages stored.

2. A communication system as defined in claim 1, in which the means for receiving incoming calls includes a PBX for receiving telephone calls.
