I have an ATA 186 and a computer connected to my new Linksys Router. I am able to make calls throuogh my ATA. It is ringing. But the moment somebody picks up the line on the other side, i couldn’t hear anything. But they are able to hear me. Some says that i have to make some changes in my Router Setup page like forwarding the Ports? Is that so? What changes should i make. Kindly let me. It will be of great help.
