We have a Talkshow 4000 that we use to bring in remote presenters to our live programs. When we fire up SkypeTX we have to wait and watch the screen to see when a call is coming in. Is there a way to hear when a call is coming in? I'm not seeing any obvious options for "enable ringing" or anything similar, and hooking up a 3.5mm cable from the green output on the Talkshow 4000 to speakers did not result in hearing a call. It's certainly inconvenient that we have to physically watch the SkypeTX screen to know when a call is happening as we are a small crew and usually will be working on other things pre-broadcast.
