    abstract =  {RFC 3263 defines how a Session Initiation Protocol (SIP) implementation, given a SIP Uniform Resource Identifier (URI), should locate the next hop SIP server using Domain Name System (DNS) procedures. As SIP networks increasingly transition from IPv4-only to dual-stack, a quality user experience must be ensured for dual- stack SIP implementations. This document supplements the DNS procedures described in RFC 3263 for dual-stack SIP implementations and ensures that they properly align to the optimizations detailed by Happy Eyeballs.},
