<p>The present invention relates to a method, an apparatus, and a system for processing a voice service. The method includes: judging whether a PSTN service exists on an access line of a main node; if no PSTN service exists, closing a switch component on the access lines of the main node so that the PSTN service on a branch node is transmitted to an HGW on the main node through the switch component and the HGW converts the PSTN service into a service based on a packet format and transmits the service based on the packet format. When the PSTN service is carried on the PS domain, no information needs to be exchanged with the network side, thus preventing impact caused by the failure at the network side and improving stability of the apparatus.</p> |
