Hi. I'm wondering if anyone else has run into this issue and found a solution. I use the free 3CX Phone software for Windows (version 6.0.19548.0) and a Logitech USB headset. In the preferences, my regular speakers are set for ringing, and my headset for microphone and in-call speaker. When I restart my computer and the 3CX phone opens (relatively late among all the programs I run), I always have to go back into the Preferences and reset the Speaker setting - it keeps "forgetting" my USB headset (only as speaker, not for microphone) and pick an output on my audio card that has nothing plugged into it. I somehow imagine the hardware drivers for the USB headset to be done loading way before the phone software can start, so I don't know for sure what is causing this. I found where the settings for the software are stored: c:\Users\MyUserName\AppData\Local\3CX VoIP Phone\3CXVoipPhone.ini I'm wondering if setting this to read-only might work as a bandaid fix... Since I'm not paying for support, all I could do was send an email to the info email address noting this as a potential bug report, but I have not heard back at all, and I probably won't. So now I'm asking the community Any thoughts? Thanks!
