摘要： A system for (and a method of) selectively establishing communication with one of plural devices associated with a single telephone number is provided. In a preferred embodiment, the system includes a wireless connect unit connected between an enterprise private branch exchange (PBX) network and a public switched telephone network. The wireless connect unit preferably serves as a gateway between the PBX and one or more remote communication devices. The remote devices can be used as standard PBX office telephones for both inbound and outbound telephone calls. Thus, features of the PBX network (e.g., voice mail, direct extension dialing, corporate calling plan, etc.) are available to the remote device even though they are not physically connected to the PBX. When the system receives an incoming call, it can route the call to an office telephone and one or more of the remote devices simultaneously or as desired by the user.
