"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

which version of OCS and OC you are using, have you applied the latest OCS patches (of march), there is a recent update for OC communicator as well, they should solve your problem
More speciically are you talking about peer-to-peer Communicator calls or Enterprise Voice VoiP calls?  If the latter this is most likely related to the media gateway configuration.  What hardware are you using for EV?

we are using OSC 2007. its a peer to peer communicator calls. previously it was working until the user did a system restore. what's the latest patch for OSC 2007, can't seem to find from the internet
Acronis True Image 2019 just released!

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

I would run the audio/video tuning wiz in Communicator.  It will allow you to test the settings for call notification and choose which device it uses.  I have seen this in these scenarios...

1) Windows XP.  
2)User had selected PC for call notification, but PC was muted.  
3) User had headset selected for call notification.
4) Bad drivers for audio device, removed from device manager, rebooted PC, plugged device in, let device find the correct driver, run A/V Tuning wiz.

Make sure the device is UC Certified...
You can also attach a different device, run A/V tuning wiz, test.
Also as a last resort, you might want to dig into the sound settings to make sure that when the device is plugged in, the system does not mute the PC speakers.
