“…systems implementing version n can read version 2, and systems implementing version 2 can read version 2 contents within a version n). The default version value (when the parameter is missing) is 1, indicating the content conforms to the requirements of [VPIM1].…”

“…A full description of usage can be found in the VPIM v2 specification [VPIM2]. This document revises an earlier sub-type registration in RFC 1911 [VPIM1].…”

Voice Profile for Internet Mail - version 2

“…The updated profile in this document is based on the experience of a proof of concept demonstration of VPIM at EMA'96 in April 1996 and a subsequent demonstration of products at EMA'97 in April 1997. This version of the profile is significantly different from the previous described in [VPIM1]. The changes are categorized as general, content, transport and compliance.…”
