I recently installed Norton 360 (first time Norton product user), and now I am unable to make voice calls in Yahoo Messenger. The option is grayed out and gives the info "<friend's> configuration doesn't appear to support voice calls" - however I know that the problem is not with the other person's configuration. I'm guessing that something with Norton 360 (firewall settings?) is blocking this. I did configure Yahoo Messenger with "Allow" in the firewall settings, however that does not fix the problem. Is there a proper solution for this?
Are you able to make Voice calls when you turn off or disable the Smart Firewall in Norton 360?
If you have not tried that, please try that first.
Apart from that, there are few suggestions put forth in the Yahoo Questions for this problem:
