    FXO Gateway Caller ID

    I installed a Grandstream FXO Gateway on the system.. Issue is there is No caller ID being transmitted to the 3CX system. There is Caller ID on the line as I had a legacy Caller ID display and was working, but not being sent on the 3CX. Everything else is working but the Caller ID.
