Support XFINITY Voice Use Lifeline Alert with XFINITY Voice


Protect your household while enjoying XFINITY Voice service.

Note: XFINITY Voice Unlimited Select and Local Select (Virginia & West Virginia Only) customers, please see information provided below.

Compatibility with Emergency Alert Services

XFINITY Voice service is compatible with personal emergency alert response systems provided by Philips Lifeline and Linear LLC. XFINITY Voice service doesn’t guarantee compatibility with other systems. To check compatibility, we recommend that you contact the agency that provided you with the personal emergency alert response system prior to installation of your XFINITY Voice service.

When to Contact Your Alarm or Device Company

For your home alarm:

  • Contact your alarm company before your XFINITY Voice installation. Provide the date and time of your installation so the alarm company can check the status of your alarm on installation day. If your alarm system needs to be reactivated after XFINITY Voice is installed, you will not be compensated for the cost of reactivation.
  • If you change your telephone number, make sure to update your alarm or personal emergency alert response company.
  • A backup battery can be installed in your XFINITY Voice modem to provide additional hours of service during a power outage. If your battery is missing or depleted and you would like to purchase a new one, visit Purchase a Battery for Your XFINITY Voice Phone Modem for more information. (Backup batteries are not available for purchase from Comcast by Unlimited Select customers or Local Select customers.)

XFINITY Voice Unlimited Select and Local Select (Virginia & West Virginia Only) Customers: Service (including 911 and emergency services) will not function during a power outage. A power outage will interrupt communication to and from non-voice communications equipment, including (but not limited to) alarm and security systems or devices, medical monitoring devices, personal emergency alert devices, home detention devices and fax machines connected to Unlimited Select or Local Select.
