[AG-TECH] Audio Problems w/ Multicast and Echo Suppression

Hi,
I just recently have upgraded an old Access Grid Node from 1.x to 2.4,
and I can get all transmissions going in both directions, video and
audio, in and out, only if I use unicast and turn Echo Suppression off.
If I turn Echo Suppression off, the meter in RAT does not show any audio
coming in, even if I can hear the audio coming back out through the
speakers in the room and the Gentner shows on its meter that sound is
coming in.
As for putting it on multicast, the meter shows input, but no one else
can hear me. I have looked in the AudioService log and can see nothing
that indicates any error, and using Internet2 detective I can tell that
I do have multicast capabilities.
The bigger issue for me would be to get the multicast working since most
rooms do not have bridges. I have no firewalls on any of the three
computers I am using here, and as far as I know the University has no
routers with firewalls in between these computers and the Internet.
Thanks,
Ben
