发明名称 Mobile branch exchange
摘要 A mobile branch exchange (MBX) allows a user of a mobile telephone to exploit the functionality of a private branch exchange (PBX) as if the user were using a PBX-connected wire line telephone in an office setting. A server is placed on corporate premises and the server is configured to communicate with corresponding client software programmed into a programmable mobile telephone. The server directly interfaces with the PBX to control call placement and connectivity and operates as an intermediary proxy for the mobile telephone. In a preferred embodiment, the server establishes a data pathway to the mobile telephone that is, from a network point of view, independent of a parallel voice pathway established between the PBX and mobile telephone.
