How to Park a call via the Manager API?

Anybody has an idea how to do this? I have tried different variations with the Redirect command but none are suitable. The only variation that parks it correct is if I do a Redirect(ChannelThatCalled,’’,‘default’,‘700’,1) but in this case the channel that called hear the 701 message and not the called channel. It also shows the call has been parked by the cahnnel who called. LOL

If there is not a way then we need to add a ParkCall command to the Manager API.
