I have received reports that CX300 users seem quiet to the person on the other end of the call. I have tested this using a spare CX300, and the volume does indeed seem quiet compared with using a headset.
Changing the microphone volume within the Lync client does not appear to make any difference, and the input volume appears to be set to 100% within the Windows sound control panel. Increasing the volume using the telephone volume control does appear to increase the volume slightly, however at maximum setting the sound appears to become distorted.
Is this a feature of CX300s or could there something else I haven't checked? We are using Windows 7 PCs with the CX300s plugged directly into the computer as opposed to via a docking station or USB hub.
Hello again everyone
Problem solved! It transpires that it wasn't so much a case of the user sounding "quiet" to callers, as not being heard at all. Upon further investigation I discovered that the headset wasn't quite plugged in, and plugging the cable in correctly has resolved the issue.
Just thought I'd let you all know before anyone offered a solution to the now non-exisistent "low volume" problem... :-)

Did you mean the Handset cord was not fully plugged into the CX300 / Handset?

Yes, the handset cord wasn't fully plugged into the CX300.
Some users have reported that the recess which contains the handset and headset sockets is a little awkward to access, and as a result a user can be under the impression that the handset cord is fully inserted when this is not the case. Once the cable has been pushed firmly into the socket and has clicked into place the issue is usually resolved.
