Emergency alerts

A panic button and emergency alerts, built into your phones.

Included on every Cannon VoIP account at no extra cost. Off until an administrator turns it on.

Panic button

A silent alarm, from any phone in the building.

Anyone can send a silent panic alert to your responders and administrators. Nothing plays on the phone it's sent from, so it won't give anyone away.

  • Pick a reason: active shooter, medical, fight, intruder, fire or other.
  • Send it from the phone app, the web portal, or any desk phone with no login. On a desk phone, dial *95 twice, or press a PANIC key your admin adds.
  • Add the room, like "Building A, Room 214", so responders know exactly where to go.
  • A desk phone panic starts in about 3 seconds.

Mass alerts

Lockdown, evacuate, all clear. Two taps.

Send a lockdown, evacuation, shelter in place, early dismissal, a medical emergency to responders, an update to parents, or your own words. Every send takes two taps, the button and the confirm, so nothing goes out by accident.

  • The phone app fills the screen with the alert and I'm safe and I need help buttons.
  • Desk phones show the message, and lockdowns play a tone and flash the phone's light red until the all clear.
  • Alerts also go out by text message, email, and a phone call that reads the message aloud, and can be read over your overhead paging.
  • Mass alerts and the all clear are limited to administrators by default.
Live board

See who's safe, and who needs help, in real time.

Everyone can reply that they're safe or need help, by tapping the app, replying to the text, pressing a key on the phone call, or from the portal. The live board shows each person, how they were reached and their answer, with needs-help at the top. Send updates to everyone the alert reached, open the alert's own chat, and end it with an all clear.

Built in

The panic button and alert templates, side by side.

Everything lives in the Emergency section of your portal: the panic button, ready-made alert templates you can edit, groups, responders, history and settings.

Groups and parents

Reach staff, parents and responders.

Start with ready-made groups for Students, Parents, Faculty and Responders, or build your own. Any business can use them, not just schools.

Groups you control
Import people from a spreadsheet, or share a sign-up link. Up to 50 lists and 10,000 people per list to start, and we can raise both.
Parents opt in themselves
Parents sign up through your link with a consent checkbox, and can manage or leave their groups with a code sent by text.
Easy to opt out
Replying STOP stops texts and calls, and every email has an unsubscribe link.
No per-text charges
Alerts are included. Texts come from your own business number, so local numbers need an approved texting registration (10DLC), which we help you set up.
Be ready

Drills, outages and connections.

Built for the day you hope never comes.

Drill mode
Run practice drills without alarming anyone outside the drill.
If your building's internet goes down
Texts, calls and app alerts still go out, because they're sent from the cloud, and the app works on cellular. Desk phones can't send or show alerts until the internet is back.
Connect your own systems
Signed webhooks and an API let your other systems react to alerts or start them.
Weather warnings
National Weather Service warnings for your area can come through the same system.

Good to know

  • It doesn't replace 911. The system alerts your people. It doesn't call 911 for you. In a life-threatening emergency, call 911 directly.
  • Alerts ring through silent mode. On iPhone and Android, emergency alerts can sound even when the phone is on silent or Do Not Disturb, once the person allows it.
  • Keep it current. You decide who can send alerts, and keep your lists, contact details and room locations up to date.
  • The fine print is in Section 5.8A of our Terms.
