Changing the Call Park Return tone ?

[jephph]

On the Adtran 706 / 712 phones, the tone heard when a parked call exceeds the timer is a constant siren -- I mean it's a CONSTANT SIREN and is one of the most blood-pressure-raising sounds that you could ever listen to.  I have a customer who is begging me to change it -- How can a change the Call Park Reminder Tone to a more soothing sound?

Since there was no reply for 6 days, I opened a support case and was informed by Adtran support that this is not possible.  The canned park reminder tone is hard-coded and cannot be changed.
