  "abstract": "The Session Initiation Protocol (SIP) uses DNS procedures to allow a client to resolve a SIP Uniform Resource Identifier (URI) into the IP address, port, and transport protocol of the next hop to contact.  It also uses DNS to allow a server to send a response to a backup client if the primary client has failed.  This document describes those DNS procedures in detail. [STANDARDS-TRACK]",
