I see some comments in May 2002 from Ivan Judson etc.
about H.323-AG gatewaying. Some mention the VRVS
reflectors, which do this.
In http://www.vrvs.org/Doc/Hardware/h323_systems.html
some systems are listed. For many (PolyCom FX, Tandberg)
it states that the H.323 client cannot decode VIC intra-frame H.261 codec

Has anyone experienced this problem with AG ?
Is there any other gateway effort or solution to the
problem originally stated by Mike Daw ?
(I note that the Polycom FX is the newer model; the older MP is OK)
