Folks,
My current view is that there are two sets of parallel goals moving forward.
The first involves enhancements to VPIM v2. I see this as the requirement
to build a reliable end-to-end service that delivers voice messages in
today's voice mail environments. Typically, this means the interconnection
of voice mail systems but potentially will involve desktop access to these
VM systems. I would see such work as VPIM onramp/offramp addressing, VPIM
Conneg/Rescap schema, VPIM directory schema and architecture, VPIM IMAP
extensions, as well as the tweaking of VPIM v2 to move it to Draft Standard,
as products of these goals.
The second involves the mulitmedia messaging future. We all have some
vision about unified messaging and the first cut at VPIM v3 was the voice
mail vendors view of this. Notably, the view that each message could be
tagged in some fashion by the originator to be primarily a voice message (or
fax, or whatever). The goal of this was to allow the transfer of this
intent for a different recipient presentation, or in the case of reception
at a limited client or server (eg, legacy VM system) the voice could be
delivered. The contrary view is that all multimedia messages are created
equal. Given this some mechanism (at sending or reception) is still
required to allow delivery to limited clients and servers. I would see such
work as the Primary content, partial NDN (DSN/MDN) as well as a new
VPIMv3/IVM profile as products of these goals. Certainly, the profile would
suggest a baseline of features that would be expected to be supported (eg,
MSGSM as the audio codec) to allow interoperability. Our challenge is to
not make the goals of this work so big (as it tends towards 'unified
messaging') as to be unattainable.
I would suggest that the Goals document is being tailored to the second case
as we are having trouble articulating exactly what we are trying to do.
Cheers,
Glenn.
