    Recently I tried to use the D-Link DVG-6004S as a VoIP-gateway in PSTN <-> SIP mode.

    I found that internal communications (SIP-phone <-> SIP-phone) is fine but PSTN <->Gateway <->3CXPhoneSystem<->SIP-phone communication is impossible.

    Firstly, I tried troubleshooting PSTN incoming call (PSTN -> Gateway ->3CX_Phone_System -> SIP_Phone). During call initiation 3CX generated server status message

    PBX just can not associate received SIP INVITE with any known entity. Create PSTN gateway with line that has internal number 10000. And read the manual.

    Yeah, I already have defined "PSTN line" and "VoIP Gateway Configuration".

    Result is the same for default Advanced options and corrected Advanced options.

    I tried two modes (with Hotline and w/o Hotline) with the same result. Then I decided that problem in 3CX.

    Here are the settings for Hotline mode (VoIP gateway web interface):
    * The Telephony settings page.
    Line: 1
    Enable: (checked)
    Type: FXO
    Hot Line: (checked)
    Hot Line No.: 100

    All other settings are by default.

    Here are the settings for "w/o Hotline" mode (VoIP gateway web interface):
    * The Telephony settings page.
    Line: 1
    Enable: (checked)
    Type: FXO
    Hot Line: (unchecked)
    Hot Line No.: (empty)

    All other settings are by default.

    In the "w/o Hotline" mode I entered "100" on the deskphone after VoIP gateway voice message.
