Scope

Voice and voiceband traffic in international networks has traditionally been transported by circuit switched systems and equipment. With the advent of the networks optimized for the transport of Internet Protocol (IP), and as a result of its considerable growth and pervasive nature, more and more voice traffic is expected to be carried over IP networks.
