Abstract

For SIP proxy failover in a SIP telecommunication network (SIPN) comprising a plurality of proxies (P1, P2) and a domain name server (DNSR), the method comprises the following steps: - storing, in the domain name server (DNSR), the addresses of the proxies that are working, - if a first proxy (P1) shuts down, then informing (42) the domain name server (DNSR) that this first proxy has shutdown; - then, if a user agent (SIPUA1) sends a domain name system request (43) to the domain name server (DNSR), sending (44), from the domain name server (DNSR) to this user agent, a response only containing the respective addresses of proxies (P2) that are working, - and then, said user agent registering itself in a proxy (P2) the address of which is contained in the response from the domain name server (DNSR).
