Service Configuration Strategy of SIP Voice Gateway

SIP voice gateway, as the NGN network access layer device, its voice service configuration capability directly affects the business experience of end users. The traditional SIP voice service configuration is mainly controlled by the IMS core network device to turn on or off the service, or the IMS core network sends the service configuration notification to the SIP voice gateway and configures the service locally in the access gateway, which makes the voice service configuration strategy lack of convenience, flexibility and robustness, and the configuration process is time-consuming and inefficient. Taking the voice service configuration of SIP voice gateway as an example, this paper proposes to move the voice service configuration authority forward to the side of SIP voice gateway. Based on the half call model of access gateway, different pre configured number tables are loaded for matching to complete the voice service configuration to solve the above problems.
