A voice loopback method, a gateway and a loopback node in a VoIP network and a network are provided. The voice loopback method in a VoIP network includes: sending, by a gateway, an internet control message protocol ICMP message, where a destination address of the ICMP message is an address of the loopback node, and the ICMP message includes a voice packet to be detected; and receiving a response message of the ICMP message sent by the loopback node, where the response message includes a loopback voice packet, and the loopback voice packet is obtained by the loopback node according to the voice packet to be detected that is included in the received ICMP message. Through application of the technical solutions according to the embodiments of the present invention, voice loopback in a VoIP network is achieved.
