I work from home and use Cisco IP Communicator as my "phone." Everything worked just fine for nearly a year, until two weeks ago when suddenly I could not hear the person at the other end of my calls. When dialing out I get a dial tone but I don't hear the other line ring. The call does complete. The person at the other end can hear me but I can't hear them. I connect to my corporate network using VPN. This issue happens both wired and wirelessly. My router is an Actiontek MI424WR. Computer is a laptop running Windows 7 Pro. I'm guessing it has something to do with port forwarding and/or inbound traffic, though I haven't changed any settings. IP Communicator works if I connect to another network, e.g. at a store with WiFi access. I only have this problem at home.
Since this is affecting my ability to do my job, I'm anxious for a quick solution.
