Currently, if I briefly press the flash hook on my phone, the caller is placed on hold. I would like for the channel to hangup if I do this instead, never placing a caller on hold (I'll be using call-parking instead). I disabled threewaycalling that is supposed to control this, but it doesn't make any difference: "threewaycalling: If enabled, you can place a call on hold by pressing a hook flash, whereupon you get a dialrecall tone and can make another call. Default: no." Here are the relevent sip.conf statements. What am I doing wrong?
