A system for (and a method of) selectively establishing communication with at least one wireless device associated with a single telephone number serving as a virtual office extension is provided. In a preferred embodiment, the system includes a wireless connect unit in communication with an enterprise private branch exchange (PBX) network. The wireless connect unit preferably serves as a gateway between the PBX and one or more remote communication devices, including at least one wireless device, associated with a virtual extension telephone number. The remote wireless device can be used as a standard PBX office telephone 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 wireless device even though it is not physically connected to the PBX. When the system receives an incoming call, it can route the call to a remote wireless device associated with a virtual extension, or to combination of devices simultaneously, or as desired by the user.
