适用范围

This Recommendation provides transmission planning guidelines for voiceband services over connections that include Internet and PSTN segments, i.e. hybrid InternetPSTN connections. In particular, "voice over the Internet" or "Voice over Internet Protocol" (VoIP) connections are considered, where at least part of the connection is over an Internet Protocol (IP) network. PSTN-only connections (i.e. connections that begin, end, and are carried only on the PSTN) are considered as the reference against which the performance of other connections is compared.
