Stay connected through the storm with Comcast Business

HOW9074-phoneSevere storms, such as hurricanes, tornados or blizzards, can knock out electricity to entire areas, which can disrupt the services critical for your business – including Voice, Internet and TV.

If there is a power outage at your location, electricity must be restored to power the gateway modem or cable modem before services can begin working again.

After power is restored, you should reboot your modem to resolve service issues.

In addition, there are Comcast Business Internet and Voice features that minimize the disruption to your business and help with business continuity.


Access your account from a smartphone or other mobile device to check your Internet connection at

Check the health status of your Comcast Business services online. The service status toolbar displays the health of your services when you sign in to My Account at via desktop or mobile.

Search for an XFINITY WiFi Hotspot and sign in using your Comcast Business credentials to access the Internet. You can also find WiFi hotspots by downloading the WiFi Finder App for Android or iPhone.


There are several solutions for our different voice services – Business Voice, Business VoiceEdge and Business Trunks - PRI or SIP

Business Voice

Consider enabling one of our call forwarding features to avoid missed calls due to a power outage.

  • Remote Access to Call Forwarding: If you need to change the phone number to which your calls are being forwarded, you can do so from a remote location to ensure your Business Voice continuity. Additionally, you may activate and deactivate your call forwarding service from a number other than your business line. Use our online tool to determine your Access Number.

  • Call Forwarding Not Reachable: Automatically forwards incoming calls to a pre-determined number when the original number is not reachable. Once the issue or outage is resolved, calls will begin routing to the business location as normal. To activate, dial *58 when your office phone is in service and *59 to disable. You can also contact Comcast Business to manage this feature remotely, or configure the feature online.

  • Unconditional Call Forwarding: Forwards incoming calls to a pre-determined number once the feature is enabled. To activate, dial *72 when your office phone is in service and *73 to disable, or configure the feature online.

Keep a corded, landline phone on hand to be able to call 911 in an emergency situation. These phones, unlike cordless phones, don’t need a separate power source to operate as they plug directly into the wall plug (RJ11 outlet).

Ensure your backup battery is working.  Comcast Business provides free battery for all Business Voice customers. The battery backup provides up to 8 hours of standby time and up to 5 hours of talk time. During an outage, make only necessary calls to ensure your battery lasts to its full potential. Comcast Business will notify you if your battery is low or missing. Learn how to troubleshoot, install or order a battery (if it is missing).

Use a mobile phone as a backup.  Be sure to program emergency contact numbers – including the police department, fire station and hospital as well as family members – into this device, and consider forwarding your calls to it before a severe storm knocks out power.

Business VoiceEdge

With Business VoiceEdge, your services are hosted in the cloud, which means your auto attendants and voice mail will continue to work during an outage. However, if you lose power at your location, your phones will not ring. Learn more about Business VoiceEdge here.

To be prepared, download the VoiceEdge Mobile App from the iTunes App Store or Google Play to use your mobile phone as your office number. Click here to learn more. Also consider enabling your call forwarding or remote features, which are available for every Unified Communications user.

  • Call Forwarding Not Reachable: This feature will automatically route calls to a pre-defined number, in case of any outage. Typically this feature is activated at install; you can easily set up and manage this feature in your VoiceEdge Feature Portal.

  • Remote Office: Turn your home phone into your work number so you can both receive and place calls as if you are in the office. Watch a video about this feature.

  • Be Anywhere: This feature allows you to integrate your VoiceEdge service with a mobile device, and use it to receive or place calls – you can even move live calls from your mobile phone to your desk phone using this feature. Watch a video about this feature.

  • Voicemail to Email: Enable this feature so if you do receive voicemail messages during an outage, you can check them from a smartphone or from an alternate location such as your home computer or laptop. You can easily set up and manage this feature in your VoiceEdge Feature Portal.

Business Trunks – PRI or SIP

With our PRI service you have the option to utilize the Destination Unreachable and Call Forward Not Reachable features, which re-route incoming calls made to your trunk group to an alternate destination in the event of an outage. This feature only needs to be activated once. With our SIP service, you can utilize Call Forward Not Reachable and Failover to give your business the reassurance you will not miss a call due to an outage. Contact Business Trunk Technical Support at 1-877-543-3961 to activate this feature.
