john_van1 Posted September 28, 2008 Share Posted September 28, 2008 Hi I just purchased Expresstalk BE for Mac and i'm using freecall as the sip service I can call people - it rings and it says its connected to the call but i can't hear anything on either side, they can't hear me, i can't hear them it says STUN server failed: sip.voiparound.com The internet connection could be down Check local firewall is not blocking UDP port 4000 Also check STUN settings or use different STUN servers. Unable to use uPNP for NAT routing (uPNP failed) Unable to auto detect public IP. Using private IP And i can't run the SIP network tool - as it says i have STATIC ip or port mapping and it says i have to turn that off - which i don't know how to do Any help would be appreciated, thanks!
