Can I plug a modem, answering machine, or conference phone into my office phone jack?
A. If your office has an analog jack and a standard, single-line telephone you may do so. However, the conference phone must be analog if you are using an analog jack. If you have a Meridian system phone, you may not. System phones are digital in operation. As such, any dial tone or normal conversation appearing on them has been generated by a remote telephone system elsewhere in your building. Even though system phones plug into what looks like an ordinary phone jack, normal telephone equipment does not operate from those jacks and may even possibly be damaged by plugging them into a system jack. Conversely, a system phone cannot be plugged into a working normal phone jack or into an answering machine connected to a regular phone jack.
