i have an 8 user UC520 demo kit and have Live Record set up on the phones. the problem i am having is that when i do an extension to extension call and then initate a live record session the extension i dialed does not hang up. for some reason that extension stays connected to voicemail. is this jsut the way the system works or is there a fix for this so when i hang up, the other persons phone hangs up as well. thanks in advance for all your help!
