Common Area Phone autodial DID on "Off-Hook"

Our organization currently has a common area phone in the reception area that we would like to have autodial a DID on "off-hook". We are currently using a Polycom CX500 running Lync Phone Edition. From what I have been able to configure so far, I cannot find an option on the device itself. Is there a PowerShell script that we can apply to this CommonAreaPhone object to have autodial on "off-hook" status?

Thanks,
Erik
