<body class='hmmessage'><div dir='ltr'>My question is not directly related to Asterisk, but I'm hoping users here might have some insight.<br><br>We have SPA504G phones with only Ext1 enabled. We use the other line keys to pick up parked calls in Asterisk via:<br><br>fnc=sd+blf;sub=1234@proxy<br><br>This works smoothly except for one scenario:<br><br>When the user presses (by mistake) one of those "unpark" line keys while in an active call with a customer, this active call and the parked call from another customer are bridged (and obviously the call is gone from our phone).<br><br>Is there a way to force the Cisco phone to put the active call on Hold before getting the parked call?<br><br>or<br><br>Is it possible to somewhat temporarily deactivate/disable the unpark line keys while there is an active call?<br><br>Thanks,<br>Mert<br> </div></body>
