The method includes: obtaining, by a branch device, a domain name system DNS resource record for specifying the location of service SRV response message; adding information of a SIP local survivable registration server to the DNS SRV response message; and returning the DNS SRV response message to which the information of the SIP local survivable registration server is added to a branch terminal, so that the branch terminal obtains an Internet protocol IP address of the SIP local survivable registration server according to the information of the SIP local survivable registration server in the DNS SRV response message. The solutions provided by the present invention ensure normal working of the branch terminal and saves costs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, device, and system for obtaining address of SIP registration server","description":"The present invention provides a method, device, and system for obtaining an address of a SIP registration server.
