    Hello. I am using 3cx v3.1 for my office. I have a remote extension (3cx VOIP Client)I would like to use and have got it setup registered and can make calls on it. The problem I am facing is when I call out the other party cant hear me. I can hear them though. I know I can upgrade to 5.1 or 6.0Beta but these versions do not work well with my sip phones. Below is the server log when I call out from extension 104. I have got the stun server set up on the client end and the client machine is setup in the DMZ. I also have listed all the open ports for both ends.

    Thanks in advance!

    Remote Extension Settings:

    Other options <<
    This section allows you to configure other options for this extension. More >
    Extension is external. Enable the "Extension is External" option if this extension is located outside of the corporate network or resides on a different subnet.
    PBX delivers Audio. You can configure a caller ID that should be set for calls from this extension. Note that many providers do not support this and this may be overridden or ignored. Toggle the "Supports Re-invite" option if call transfers are not working reliably for this extension. Some older SIP phones do not support changing call parameters during a call. Toggle the "Supports 'Replaces' header" option if call transfers are not working reliably for this extension. Some older SIP phones do not correctly implement this option.
    ser Status allows you to define whether the user is available to take calls. If set to "Away", the extension will behave as configured in the "Phone Busy" tab of the "Destination Unreachable" section.
