Video / Audio / Screen Share have all stopped working...

Question

I've got two business partners in remote locations. All three of us are on MacBook Pros. Mine's several years old, but theirs are both new. We're all using MacOSX 10.5.6 and iChat 4.0.7. All three of us have been able to do video, audio and ScreenShare with no problem up until last week. To the best of my knowledge, none of the three of us has had a hardware change or a software change. We can chat fine.
Every time any of us tries to initiate video, we get "Waiting for Response"... then "Starting Video" when he accepts... then "There was a communication error during your chat"... "Did not receive a response from X" when in fact he is clicking accept.
Enable Screen Sharing / Video / Audio is all selected in the iChat video menu. Based on previous threads I'd read, we've also tried the System Preferences / Sharing settings, unchecking "Remote Management" and checking "Screen Sharing". Nothing's helped so far.
One of us is on a Linksys router (me), one on an Airport and one on a Netgear router. Again... all worked fine until last week. Any help you can offer would be greatly appreciated.
Any suggestions would be greatly appreciated.

Hi Skippy,
Welcome to the    Discussions
It is difficult to say what is going on here and three people with different routing devices all seem to have the same problem at the same time.
My firts thought would be that if the routers are doing DHCP to the LAN (computers) and that POrt Forwarding was also used the IP the computer has may have changed and the Port FOrwarding will not be pinting to the IP the computer now has.
However this is unlikely with three devices at the same time.
The Netgear is also probably doing UPnP by default and therefore not doing Port Forwarding.
Te Linksys can do UPnP but needs it Enabled.
The Airport does something called Port Mapping Protocol (Apple's version of something similar to UPnP) and needs it turned on.
Again it seems strange that buddy to buddy individually you are all having issues.
Are you all using the same ISP ?
Has there been a Speed bump in service ?
From Table 1 can any of reach the Apple test accounts ? (Uue the ones that end in @mac.com)
