Convenience ports

If you want to connect another device (such as a modem or fax machine) to the wall jack, you can use the jacks on the phone labeled AUX. These convenience ports use lines 3 and 4; a call picked up on line 3 or 4 at another extension may interrupt fax, modem, or message transmission.
