1. A method for performing remote network management on a voice home gateway terminal, comprising: determining, by a remote network management server, whether to manage non-voice services of the voice home gateway terminal; if it is determined by the remote network management server to manage the non-voice services of the voice home gateway terminal, transmitting, via a voice signaling control protocol in a voice signaling channel, by the remote network management server to the voice home gateway terminal voice signaling including a non-voice triggering identifier to notify the voice home gateway terminal to request, via a non-voice signaling control protocol in a non-voice signaling channel, non-voice configuration information from the remote network management server based on the voice signaling including the non-voice triggering identifier and to process, via a non-voice signaling control protocol in a non-voice signaling channel, a non-voice service according to the received non-voice configuration information; and if it is determined by the remote network management server not to manage the non-voice services of the voice home gateway terminal, transmitting, via a voice signaling control protocol in a voice signaling channel, by the remote network management server to the voice home gateway terminal voice signaling without non-voice triggering identifier to notify the voice home gateway terminal to process voice service according to the voice signaling via a voice signaling control protocol in a voice signaling channel, wherein the non-voice configuration information comprises at least one of file name, upgrade server name and protocol way; and the method further comprises: after receiving the voice signaling from the remote network management server, determining by the voice home gateway terminal whether the voice signaling contains a non-voice triggering identifier, processing by the voice home gateway terminal a voice service according to the voice signaling when no non-voice triggering identifier is contained, and requesting by the voice home gateway terminal non-voice configuration information from the remote network management server when a non-voice triggering identifier is contained and processing by the voice home gateway terminal a non-voice service according to the received non-voice configuration information, wherein the method further comprises transmitting, by the voice home gateway terminal, a registration message to the remote network management server to establish a connection with the remote network management server before the remote network management server transmits the voice signaling to the voice home gateway terminal.
