Method of communicating with subscriber devices through a global communication network
When a call out is done by the destination communications device (11), the calling access server (15) generates the call-out packet, which packet is then sent to the called access server (15) through the Internet (16). The called access server (15) sends a ringing signal to the destination communications device (11). When the destination communications device (11) responds to the ringing signal, then the called access server (15) generates an acknowledge packet and returns the packet to the calling access server (15) through the Internet (16). The calling access server (15) then begins charging, and returns the acknowledge signal to the calling communications device for starting talk over the telephone. After that, talk packets are exchanged through the Internet (16). Finally, the termination is generated when the telephone call termination is detected with either of the calling and called access servers (15), and the termination of the telephone call is performed.
