Hi, I just tried to use google voice to contact someone, after 2 'dialing sounds', I couldn't hear anything. After I stopped iptables, I can make phone calls via google voice successfully. I searched the web, and found 2 possible solutions: [1] and [2]. Then I added iptables rules according to their instructions, but none of them worked. Also, I noticed that my browser just kept trying to receive/send data to relay.google.com (Waiting for relay.google.com) How to configure iptables so I can use google voice with iptables enabled?
