In this final chapter we briefly review some issues associated with directions in which the telecommunications networks of the world are currently evolving, including wireless networking, Dense Wavelength Division Multiplexing, DWDM, and MultiProtocol Label Switching, and how these developments impact packet transport of voice. We conclude by examining migration strategies for carriers to transfer voice from circuit to packet networks.
