cc Details Callback Delay
The time, in tenths of a second, which the router will wait after clearing an incoming call whose call details entry specified that the caller should be called back before making the return call. The purpose of this object is to allow the user to specify a delay in callback which will allow the network to properly clear the call at both this end and the remote end.
