Does the CM provide a feature for ring-back (re-ring) of calls on hold when the hold time exceeds a threshold? Is the feature assignable by set, class of service, or system? Is the ring-back interval set individually or as a system-wide timer?
An alternate to your holding a call would be to Park the call. You can adjust the "Call Park Reversion" Timer to set how long the call will remain parked before buzzing you back. That's the best that can be done now.
