The new version V.66 does support audio. It is availiable on the White Pine
server at

OK... This is a problem for modem users.

Won't argue here, however, audio can be heard if the sender is using the
delta-mod 16K codec.

This is wrong... You simply need a VGA or SVGA with a monitor (is that a
video controller?)

That is true.

This is TOTALLY WRONG. The enhanced version of CU-SeeMe from White Pine
WILL be compatible with the Cornell client.

Hmmm... I wonder why you are having all these problems... Others have
similar configurations and do not experience as many problems.

The V1.0 release will have a quality 8K audio codec. This will allow audio
only to be received over a 14.4 modem. The video codec will also be
reworked with some better bandwidth management as well, the target of a
28.8K modem will be achieved.

Sorry that you were not able to put your project together. Others have been
successful doing similar projects. You will probably not find any product
that meets your expectations and may need to adjust what your scope is.
Until the enhanced version is available, you will have difficulty with
audio over modem connections.

White Pine is committed to enhancing CU-SeeMe and making it a commercially
viable product. Our target is to have a version that supports 28.8K modem
connections for a single point conference or receive only broadcast. Your
project would fit the specifications for our V1.0 release. Look for this
release before the end of the year.
