Emergency and security management using E911

Updated 1/16/2019 8:35:53 PM by Comcast Expert


Be prepared in case of an emergency. Get set up to use enhanced 911 (E911) and integrate your current security system with your Comcast Business Voice or VoiceEdge Select service.

Enhanced 911

Enhanced 911, or E911, is just like regular 911 except that your telephone number and location are automatically transmitted to the operator during the call. Here are the steps you need to take to support trouble-free 911 access:

Keep your address up to date

In order for your 911 calls to be properly directed to emergency services, Comcast must have your correct service address. If you move your Comcast Business Voice or VoiceEdge Select service to a different address without notifying us, 911 calls may be directed to the wrong emergency authority or may transmit the wrong address.

Prior to changing your office address, please call 1-800-391-3000 and notify Comcast of your new address. It will take several business days to update your service address in the 911 system.

Be prepared in case of outages or technical problems

The embedded multimedia terminal adapter (eMTA) that is included with your Comcast Business Voice service combines delivery of high-speed data with voice over Internet protocol (VoIP) services by connecting regular, non-IP telephones and terminal equipment (like a fax machine) to the Comcast managed network.

Comcast Comcast Business Voice service uses the electrical power in your building. If there is a power outage and the battery backup in your eMTA is not installed, fails or is exhausted after several hours, you may not be able to call 911.

Keep in mind, you may not be able to make calls (including calls to 911) if there is a problem with network facilities such as: network congestion, network/equipment/power failure, or other technical issues. 

Comcast Business Voice services and alarm systems

Fire alarms

Comcast Business Voice service supports connections to fire alarm systems. However, some fire alarm providers have not approved the use of new technologies, such as VoIP (voice over Internet Protocol) service with their systems. Check to be sure that your fire alarm system is compatible. If your fire alarm system is not compatible with IP telephony, you may consider having a phone line with traditional service integrated with your fire alarm system for use in an emergency.

Security systems/alarm service providers

Many customers use Comcast Business Voice service to support their alarm systems; however, you should check with your alarm system provider to make sure that they have no issues with VoIP connections.
