Abstract
Methods of routing an incoming call to a mobile telephone received at a wireless enabled private branch exchange (PBX) include issuing a location request query to an element of a wireless communications network to which the mobile telephone may be subscribed, receiving a location request response from the element indicative of a status of the mobile telephone on the wireless communications network, and forwarding the incoming call to a voicemail mailbox associated with the at least one mobile telephone if the location request response indicates that the mobile telephone is not available to receive a call on the wireless communications network. The incoming call is forwarded to a telephone number associated with the mobile telephone on the wireless communications network if the location request response indicates that the mobile telephone is available to receive a call on the wireless communications network. Corresponding communications systems and private branch exchanges are also provided.
