Can't hear anything: HELP

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!
