Registering with SIP servers for IMS using a fully qualified domain name

摘要

A fully qualified domain name may be used to identify a session initiation protocol server with which a client device may connect to IMS services in a network. In one implementation, a network device may receive a request to register a client device for IMS services. The network device may determine a fully qualified domain name corresponding to one or more SIP servers that process SIP signaling packets for the client device and transmit a message initiating resolution of the fully qualified domain name into a plurality of IP addresses.
