I'm able to call people from the phone and they can hear whatever I say, but I hear nothing whatsoever.
When I first pickup the phone I'm able to hear the dial tone and I can hear the numbers as they are being pressed so it isn't a problem with the handset.
I've checked to make sure there isn't anything setup for a headset or anything like that, but I can't figure out what the problem is.
Anybody have any ideas?
Edit: Found somebody else with a similar problem and it ended up being that the firewall was letting traffic out but not back in, which is why the other person could hear them, but they couldn't hear the others. Will update this once I take a look.
To the guy who asked why I would ask the forum...the answer is because it was likely related to an IT issue (i.e. a firewall issue).
