The embodiment of the invention provides a communication method and
system of an interphone. The method comprises the following steps: a first protocol conversion
server receives a first IP voice datapacket sent by a first forwarding
station in an IP network, performs protocol conversion from the IP network to the articulated naturality web on the first IP
voice data packet to obtain a first articulated naturality web
voice data packet, and sends the first articulated naturality web
voice data packet to an articulated naturality
web server in the articulated naturality web; the second protocol conversion
server is in the articulated naturality web; a first articulated naturality web voice data packet sent by the articulated naturality
web server is received according to a downlink
communication link configured for the second protocol conversion
server, protocol conversion from the articulated naturality web to the IP network is carried out on a first articulated naturality web voice data packet. According to the invention, the first IP voice data packet is acquired through the first
repeater, and the second IP voice data packet is sent to the second
repeater in the IP network so as to decode the first voice data into the first voice
signal and forward the first voice
signal to the second interphone for playing, so that the communication range of the interphone is greatly expanded.
