Vonage may not be compatible with some home alarm systems that are set up to automatically contact central monitoring stations. Vonage does not guarantee that Vonage will work as the connection between alarm systems and monitoring stations. Vonage contractors will not connect Vonage to any alarm systems and Vonage will not provide technical support to this type of connection. In the event of power outages or disruptions in internet service, Vonage and any devices dependent upon Vonage connectivity will not work.
