[Freeswitch-users] Changing callerid before/after call pickup

Hi, currently I'm playing around with call pickup and Snom phones. I'm using the intercept function for that. My "problem" is now that after the call pickup (which works fine) I don't see the caller id of the original call. Instead I see the pickup code, e.g. *820 I've tried to change nearly every channel variable (before doing the call pickup), but the phone won't display the caller id. Does anybody know how to change that? Thanks, Klaus
