Hi Everyone Having issues using other peoples (who I dial) automatic attend systems. When connected, I cannot dial any tones. I hear them on the hand set, but they are not passed thought to the caller. I have tested this by ringing my mobile and from the 3CX pressing a 1, 2, 3, * or ‘, nothing happens. I have a Granstream GXW4104. It is not working on any handset or 3CX Windows Phone.
