The Sofia settings of tcp-pingpong and tcp-ping2pong aren't documented other than to indicate that they exist. It would be helpful to know what they do, if anything. I would be happy to update the documentation if someone wants to indicate explain their function -- Chris McMacken TechOps Engineer 10 S 5th Street Ste 650 Minneapolis, MN 55402 cmcmacken@gravie.com | www.gravie.com
