We have a Unity 3.0 and there is low volume when Voice mail messages are
accessed from a remote location.As 3.0 does not have any AGC parameters,we need to adjust the wave gain parameter.Bur when we looked in today,we did not see the Wave gain.exe file in the Unity server.Must we download the file and then change the record and playback gain in it.Or is there some place else where we can modify the parameters and get a good volume on the messages.Please advice.
Do I just download and run the .exe file or is there a specific file or directory that this should be stored in.After downloading how do I change the parameters?By saying G711,do you mean the codec for the calls made into Unity by the remote user.Please explain.
After you run it you make the changes in the registry. You can get to the registry by typing regedit from command.
By g.711 I mean that any g.729 calls you have will not be affected by your changes.
Remote sites (CCM regions) are usually setup to use g.729 to conserve bandwidth. If that is the case and you still need to adjust the volume you might need to look at upgrading to 3.1(5) to get AGC or getting hardware transcoding. But then hardware trancoding doesnt get accounted for correctly with locations based dialing. Unity 3.1(5) probably makes the most sense if you are using g.729. :)
Could you advise me on how to tweak the values once I have it downloaded.Should I make it positive like changing the value to 1 or 2 DB or keep adding until the quality is good.When do we use negative values.Once I change in the registry does it automatically get updated on the wavegain.exe file.Please advise.
The home page for this tool on AnswerMonkey covers how to set the values in the registry once you find ones you like. As the help out there says, no, the tool does not set it for you - I don't have code for the tool so I can't fix that - this was given to us by another group. The page for this tool is here:
