    Ok, got a green light for my voip provider under line status, make an outgoing call - rings all good apart from when the phone is answered, no sound! same happens if I call in through my voip proviider, no sound.

    I ve put all of the required firewall ports in (SIP, STUn & RTP) and can see the traffic going through ok via ethereal but no voice...

    I m tearing my hair out here, I presume its either a codec or my voip provider as I cannot figure this one! pls help...

    TIA

    Further info, I ve found when initating an outbound call from an internal extension I m getting this error logged

    22:21:53.578 MediaServerReporting::STUN [MS101003] Call(1) Ln:10000@Internode: Possible firewall problem. Address mapping failed on STUN server 64.69.76.24:3478 for local address ":9028"

    The weird thing is earlier I m getting

    CM115002] STUN resolved external IP=211.26.85.226:5060 by server 64.69.76.23

    so surely STUN is working? my firewall is indicatiing traffic is going backwards and forward and ethereal is showing up all the right traffic???
