Every Caller, Routed to the Right Place

Phone menus, ring groups, business hours, holidays and forwarding rules, with one-click AI greetings.

Published August 7, 2026 · Cannon VoIP Team

“Press 1 for sales” is the part everyone knows. What separates a well-run phone system from a frustrating one is everything behind that menu: where calls go at 2 PM versus 2 AM, what happens when nobody in a ring group picks up, and how a holiday closure gets handled without someone remembering to flip a switch. Cannon VoIP gives you all of it, buildable yourself in the portal, with our team on call when you’d rather describe it and have us build it.

The building blocks

Auto attendants (IVR menus)
A menu greets every caller and routes each keypress where you decide, a department, a person, a voicemail box, another menu, or an outside number. Menus can go as many levels deep as you need, callers can dial any extension directly, and, when you turn it on, callers can say their choice instead of pressing it. Set a menu’s language and its spoken options are written and voiced in that language, and a menu key can connect callers through a live interpreter, who joins when someone answers.
Ring groups
Ring a team, sales, support, the front desk, in order or spread calls to whoever has been idle longest, with a fallback destination when nobody answers, so calls never dead-end.
Business hours, holidays & company status
Set office hours for each phone number by day of week, with an after-hours destination. A holiday calendar, with this year’s US federal holidays added in one click, switches the company to Holiday on each listed day and back afterward. A status switch in the portal header (Normal, Holiday, Emergency or Snow Day) overrides normal routing when you need it. A Weather page shows the National Weather Service forecast for your building, and severe weather warnings reach everyone in the apps and on desk phones, so you know when it may be time for Snow Day.
Personal call rules
Each person can set Do Not Disturb, forward all calls, follow me (ring their phones, then a colleague or a cell phone, step by step), forwarding by status like At lunch or Out of office, personal office hours, and rules for specific callers or prefixes. A colleague’s call that you decline, miss, or that reaches you on Do Not Disturb goes to your voicemail.
Caller timeout for repeat callers
A number that keeps calling the same person or group is paused for a while. On by default: the 5th call within 5 minutes starts a one-hour timeout, and you can change the limits, exempt a number, or end a timeout early.
Missed-call text back
Send a missed caller a text automatically, at most once a day per caller and never overnight.
Internet outage backup
If every phone on the account goes offline, calls forward to the number you choose instead of going nowhere.
A "What happened" panel on every call
The call log shows, step by step, where each call went and why: which phones rang, for how long, who answered, and when screening or a timeout changed the call.

Greetings in one click

The chore that kills most phone menus is the audio. With Cannon VoIP, every new extension gets a spoken voicemail greeting automatically, and menus, queues and voicemail get a one-click AI greeting in the voice and speaking speed you choose. A menu’s AI greeting is built from its own options and names, so after you change a key, one click gives you a greeting that matches. You can always type the words, record your own or upload audio instead.

Where the calls can land

  • People and teams: extensions, ring groups, and call queues with place-in-line announcements and callbacks.
  • Voicemail: every voicemail is transcribed, with a one-line AI summary, and emailed, so a missed call is a readable message in your inbox.
  • A live person, always: route overflow or after-hours calls to our Live Answering team, or to the AI receptionist.
  • Anywhere else: outside numbers, cell phones, another office, routing doesn’t stop at the edge of the phone system.

All of it is managed in the self-service portal, included with every account, and during onboarding we build your initial call flows with you, so day one already routes right.
