    Hi there,

    I have setup a generic type SIP gateway, and no issue to register to 3CX server, howeve, when I dial to this FXS gateway, it always reply Busy (for sure it is not).
    For the 3CX supported GXW gateway, no such issue.
    Q1: anything wrong with my setting?
    Q2: Notice that there is license limit warning message, what does it mean? my license is SB and there is no active call at all.

    So the incoming trunk is set to send the call to Ext 23? Which is forwarded to 21815 ?

    which is what exactly? Is it another outside call attempt?

    Probably the gateway is not detecting a hang up and tieing up the call and therefore a license. Use a supported gateway is the solution
