An apparatus comprises two processors 105,107 for supporting a remote terminal 101 in a packet (eg WiFi [RTM]) and circuit switched (eg GSM) mode of operation respectively as well as two interfaces 113, 117 for interfacing to an external circuit (eg PSTN) and packet switched (eg VoIP) network 111,115 respectively. A first selector 109 can select a remote terminal communication link as a packet switched mode communication link or a circuit switched mode communication link and a second selector 119 can select an external voice communication link as a voice communication link of the external circuit switched network 111 or a voice communication link of the external packet switched network 115 in response to an identity of the other party involved in the call. A conversion processor 121 can support the voice communication by conveying voice data between the selected remote terminal communication link and the selected external voice communication link. The apparatus may specifically be a home gateway facilitating operation in a combined packet and circuit switched environment. |
