"Did not respond" (similar threads have not yet solved)

Question

Please help.
Background: new mac user who bought powerbook g4 to keep in touch with family overseas on iChat. continually receiving 'did not respond' message whether initiator or receiver of video chat invitation (text chat is OK). I've read several threads on the subject and reconfiguration attempts to date have not yet solved the problem.
Current setup:
Westell 6100 modem with DSL connection >>
Linksys RT31P2 voip router >>
Linksys WRT54GX4 wireless router
--Ports open on both devices per thread and portforward.com suggestions: 5060, 5190, 5220, 5222, 5297, 5298, 5353, 5678, 16384-16403
--mac firewall off
--tc/ip airport connection using DHCP
Other solutions attempted:
re-order of routers, modem>>wireless router >> voip router = no success
Thank you kindly in advance for any advice.

Hi betseygkeely,
Welcome To The Apple Discussion Pages.
If you are using a VoIP service reorder the devices.
Modem <-> Linksys WRT44GX4 <-> Computers and Linksys RT31P2 on different ports from the Links WRT
Make sure the Westell is not doing DHCP.
Get the Linksys WRT45GX4 to do any DHCP if anything does.
Set the UPnP in the Linksys WRT45GX4 in the Adminsration tab.
