Hi folks, need some input on an issue we're experiencing with our softphones. The issue we're having is the caller can't hear us but we can hear them.This doesn't happen all the time, it's sporadic. When this happens it happens to 2 different ppl @ the same time, not just one person. This is also only happening to folks who are vpn'd into our network, doesn't happen to folks in the office. I can use my softphone all day here at work with no problems. But if I work from home and vpn into the network that's when it happens. We're using intel dual core processors on desktops and core 2 duo on the laptops.The headsets are Plantronics DSP400. Applications running are microsoft outlook, I'll have to get with our outside salesman to see what other apps their running.It's strange and has me scratching my head.HELP!!
