ABSTRACT:
A home wireless router establishes a Wireless Local Area Network (WLAN). The home wireless router services a plurality of wireless terminals within the WLAN service area, the plurality of wireless terminals including at least one Voice over Internet Protocol (VoIP) wireless terminal. The home wireless router receives a request to terminate a WLAN VoIP call to the VoIP wireless terminal. The home wireless router determines that the VoIP wireless terminal is currently servicing a cellular call via a cellular network. The home wireless router causes the cellular network to be misled into concluding that another cellular call is to be serviced by the VoIP wireless terminal, the cellular network places the cellular call on hold in the incorrect conclusion that it will service the another cellular call, and the WLAN VoIP call is terminated to the VoIP wireless terminal.
