The Motorola ML1000 Desk Phone Base Station with Digital Receptionist and Digital Answering System can be set to automatically pick up a ringing line after an answer delay that you program. When the digital receptionist is turned on the ML1000 will then automatically play a designated greeting to your caller. Build a 1 to 4-line phone system and wirelessly connect up to 10 ML1100 desk phones and/or ML1200 cordless handsets (sold separately) to the base station. Only the ML1000 base station needs to be connected to a phone jack.
