For some reason when I go to preferences to enable logging (sip, engine, notifications), it's only writing the sip log and not the other two. <br><br>3. Has anyone reported issues with or do you know of any issues with PTHVolume? <a href="http://pth.com/products/pthvolume/">http://pth.com/products/pthvolume/</a> I've seen errors in the system logs on the workstations I'm trying to troubleshoot. I don't know if it's the cause. Removing the app seems to improve the situation, but a couple of users say they continue to get dropped calls and others say no dropped calls. These are the entries, dunno if they help:<br>system.log:Dec 9 11:46:37 mini-52 [0x0-0x1b01b].com.pth.PTHVolume.app[779]: PTHVolume(779,0xb0218000) malloc: *** auto malloc[779]: error: GC operation on unregistered thread.
