automatic un-park call

[le_papa]

im using V11 and we want to use the option to send back call to user who parked a call.
ex: when extension 200 park in *01, then after 90sec. call goes back to 200.

in "advance setting" in the tab "call parking", "enable automatic pickup..." is ticked and set to 90sec

I tryed with external and internal call.
direct call and call that goes trought IVR.

Any idea someone ? Did i missed something ?

Thx !
