A multi-PPPoE(Point to Point Protocol over Ethernet) session supporting method of a keyphone system is provided to be capable of supporting multiple PPPoE sessions on one transport, thus the keyphone system can access various PPPoE ACs(Access Concentrators). An IP(Internet Protocol) stack(P103) forms multiple channels between PPPoE protocols(P105) via a PPP(P104). PPPoE packets inputted to each channel are multiplexed according to the PPPoE protocols(P105) to generate one Ethernet packet. The multiplexed Ethernet packet is delivered to a bridge(P102) through a q-interface(P107).
