A:Answer Thank you for reaching out! The Answering system is designed to pick up calls from the landline. In order to receive messages on your cell phone, you would need to have a voicemail service active, and that can be accessed from the Panasonic phone. In regards to the Caller ID, that is specific to the cell phone and it is not passed to the Panasonic phone. If you would like to see the callers from your cell phone, you would have to have the numbers saved in your phonebook.
