    I have my 3CX system installed now and I can receive inbound calls with one slight hitch. I can hear the external caller talking but they cannot hear me. I can make outbound calls perfectly. I couldn't see anything obvious in the 3CX server status screen so I turned on verbose logging and done a quick test and this is the result. I am using VOIPon by the way and Linksys SPA942 handsets. I thought it might be the firmware on the SPA942 which was v5.1.15(a) so I upgraded them to the latest version without any change.

    I am using VOIPon as my provider. My firewall is a zyxel Zywall USG-200 which has passed the firewall test ok.

    This is what I have got in the 3CX General Settings

    Default STUN server address: stun.3cx.com Port 3478
    Default second STUN server address: stun.xten.com Port 3478

    Timeout time for STUN response (ms) 3000
    Recheck external IP every (sec) 1200

    On the Linksys SPA942 the "Stun Enable" was set to no. I enabled it and set the server to stun.3cx.com. Makes no difference.

    try other stun servers
    did you istalled 3cx on a fresh xp

    if you can reinstall every thing
    reset your linksys to factory set and set again
    did you used the auto-provisioning
