Private park pickup from a cordless phone handset that is not presence enabled

Would like to be able to use a private park with a cordless phone to pick up the park.  We have several shop managers that work in loud environments that can't hear what the public park location is over the speaker...or would like to be able for the office staff to be able to send a call to a set public park so it is the same location each time for the cordless to pickup.
