SIP Connection Errors

I've been having connection problems (i.e. can't ever connect via video/audio/screen-sharing) for several months now and I'm fed up - need a solution. 🙂

I've seem this same problem posted many times, but there's never a clear answer (despite Ralph's courageous attempts). Everything was working fine before (in 10.5.6), and out of the blue, everything just seemed to stop working. I upgraded to 10.5.7 thinking that perhaps it would refresh the iChat install, but no joy.

I've tried all of the common tricks (clamping the bandwidth, opening up the firewall, removing sys hacks, etc.) with no help. I get the same results while trying to connect to a remote user via AIM, with a LAN user via Mac.com, or with a LAN user directly via Bonjour.

I'm on a G5 Quad with an iSight, tons of RAM, a fast 6M/756k DSL pipe routing through a TimeCapsule with NAT port mapping on, and nothing else particularly weird installed in my system. Skype works fine, so this seems to be exclusively an iChat problem.

I'd really appreciate any suggestions. I'm a fairly savvy Mac user (21 years), but this one has me stumped and I REALLY don't want to do a clean install.

BTW, my laptop also seems to have this problem now, but I believe my kid's eMac can still audio/video chat just fine, which tends to rule out a problem with my router/modem (I'll verify this tomorrow and post a follow-up).

Here's my latest console dump from an audio chat test to appleu3test03 (everything but the binaries):
