Is ringing sound of incoming call heard through wired headset on 7205, 6205, or 2605?

I have an unusual application in which I must connect to the 2.5mm wired headset plug, and then locate the phone where I cannot hear sounds coming from the phone itself. Therefore, I must be able to hear the ringing sound in the headset. Also, I am unable to touch the phone, so I need the option of “auto-answer when headset is connected” so I can accept an incoming call.
Can anyone verify that these features exist on any of the models 7205, 6205, 2605?

I am considering these phones because I am a currently a Verizon customer, and don’t want to switch service providers.

I would appreciate any help.

Thanks,
Chris
