I am quite befuddled at this point. Have had iaxRPT running on my nodes for quite sometime and I have a couple Win10 laptops that work just fine with it. Never a problem. Buddy is getting ready to go on some extended travels and wanted to use iaxRPT to connect with my node and stay in touch. Can not get it to work on his laptop. Can not get audio to his speakers. Shows on iaxRPT VU but can not get it to speakers. Yes, audio per app is turned up in settings. Second issue, will not key up anything on network. PTT goes red but nothing else happens. Looking at Asterisk CLI on my node see no activity at all when he tries to transmit. He is another city so we have been doing this via phone and Teamviewer. All of his settings match the ones that I'm using on my Win10 machine as far as I can see. Have tried running as administrator, compatibility mode and turning firewall off for giggles. Probably something really stupid, but I'm overlooking it. Hope one of our resident gurus may have an idea. Going to go take a couple Tylenol's now. Ed W8VT
