Can the Lyric Controller Communicate through a Phone Line

No, the Honeywell Lyric controller is not able to communicate its alarm signals through a phone line. Previous Honeywell all-in-one wireless security systems did allow for this communication path but, with the Lyric controller they have moved on from this communication path. 

The Lyric Controller does not support phone line communications at all. Communication of alarm signals for the Lyric Controller is done via built-in WiFi communicator or add on Cellular communicator.
