H.320 to H.323 Gateways: Will They Decompose?

Without going into specific product plans, it is clear that for deployments
that want to support both voice AND H.320 - deployment of "video only"
gateways does not make any sense, and the same gateway needs to support
both functions.

So, if voice will opt for decomposition, it should find a way to
accommodate the video/data side. BTW - H.324 "died" because there was no
real application/network that supported it well. It seems to me that in the
new networks (e.g. ADSL or Cable or wireless local loop) it might still be
useful. Should we support it in Megacop?

This is addressed to the experts of Study Group 16, but has impact on the
priorities of work both for Megaco and for H.GCP.  The question, which I
raised obliquely in a previous exchange on co-location of H.245 signalling
with the Media Gateway function, is whether any vendor will actually create
a decomposed H.320-to-H.323 Gateway.  If not, we can stop worrying about
to accommodate H.320 in the Media Gateway control protocol.
