    I have setup a 3CX Box and it's perfectly working since install, i have a hardphones and softphones on it.

    The setup is is as follows:

    3CX:
    Port Mapping:Every need it port mapped
    pstn line: linksys 3102
    Ext: 301 as external & bind to media server
    STUN: stun.3cx.com

    BT-102: On different network behind router
    DHCP: OK
    STUN: stun.3cx.com
    Nat Traversal: YES = detected NAT type is full cone
    NAT: FULL CONE
    STATUS: registerd = YES
    Local SIP PORT: 5060
    Local RTP Port: 5004

    Can do:
    Can make call from the external BT-102 to PSTN Numbers via 3CX and internet every call its fine and works perfectly:

    Can't do:
    If i call pstn >> 3CX PSTN(linksys 3102) and dial extension 301(bt-102 external) it rings and i can see even the number but when i hook off there is no sound, and on the other end it's like the transfer music.

    Estrange:
    It works perfect extension 301 on the softphone x-lite as external both ends.

    Any help

    I trying everything related to nat and firewall behind the hardphone even map the ports and nothing same result:

    Hello,
    Was this issue ever resolved? I am having the exact same issue with a BT 100. Is it the phone, or a setting that can be changed? Anyone gotten it to work?!

    Thanks!
