Hi all, I have set up a GNUGK which lets my calls from openphone through Cisco 5300 to PSTN smoothly. However, when I ran openphone behind a Buffalo NAT, I could not hear anything from PSTN but my voice passed through NAT to PSTN correctly. I have configured openphone to use STUN. Any one out there experienced the one-way voice problem like mine? How can I fix it? Many Thanks.
