This document discusses how IPv6 will impact telecom systems and voice over IP (VoIP) applications. It notes that the exhaustion of IPv4 addresses means IPv6 adoption is necessary, but that IPv6 presents challenges for VoIP including longer and more complex addresses, multiple addresses per interface, and compatibility issues between IPv4 and IPv6 networks and protocols. The document recommends solutions like address compression, neighbor discovery, happy eyeballs, and protocols like SIP, SDP, ICE and STUN/TURN that help with the IPv6 transition. It also provides examples of IPv6-ready VoIP software and resources for testing IPv6 networks.
