Honestly, am comfused. I use gtalk2voip call-out services on Yahoo messenger, but each time i try to initiate a call. Yahoo messenger pop up reads; "no voice signal detected from gtalk2voip" i have disable all firewalls and did everything neccesary, but all to no avail. Please your advice is highly needed

This happens when Yahoo client and GTalk2VoIP gateway cannot pass RTP (media) streams to each others, usually due to NAT traversal issues. You can fix this either by 1. moving to another ISP with better NAT policies/configurations, 2. change your DSL modem to something less "chinese" with proper NAT implementation. Unfortunetly NAT traversal issue is the conerstone for all VoIP world and there's not much can be done about it on server side .
