    abstract =  {{[}RFC3551{]} defines the AVP RTP profile, which is the basis for many other profiles, such as SAVP {[}RFC3711{]}, AVPF {[}RFC4585{]}, and SAVPF {[}RFC5124{]}. This document updates {[}RFC3551{]} (and by extension, the profiles that build upon it) to reflect changes in audio codec usage since the document was originally published.},
