G'day Ben I recently released a document at agcentral in regards to "Improving your AG in Preparation for a Quality Assurance Test". Part of this document contains a section on "Testing an AG's Network" which can be found at http://agcentral.org/help/tutorial/qualityhelper/qunetwork
Not sure if it is of any use, but thought I would send it to you in case it helps. Cheers, Jason. -----Original Message----- From: owner-ag-t...@mcs.anl.gov [mailto:owner-ag-t...@mcs.anl.gov] On Behalf Of Ben Ware Sent: Friday, 2 September 2005 6:10 AM To: ag-t...@mcs.anl.gov Subject: [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
