I have 3cx running on a win 7 64 bit pro install. I have set up skype gateway and all seems to be working I can get inbound calls and make outbound calls. I have a mic set up on my PC that I klnow works "I use it with Ventrillo" I can hear the outside called no problem but they cannot hear me. Any ideas what might be wrong. I went into the softphone settings and have tried every one of the recording input devices listed.
