Transfer to an extension on hold

Is it possible to have a customer call be sent “on hold” to an extension? For example, Bob calls an 800 number and the receptionist redirects him to the CEO (who is currently talking to his secretary). Since the CEO is busy talking, Bob is immediately placed on hold.

A parking lot would be a better choice but I am examining alternatives.

It would be nasty but you could setup a queue for each of the extensions you wanted to do that for. Just make the extension a static member.
