Welcome to your central directory for managing your Cannon VoIP system. By using the shortcodes (Feature Access Codes) below, you can control your call flow, privacy, and recording settings directly from your phone's keypad.
[!WARNING] USE AT YOUR OWN RISK: These codes give you direct control over the system's "brain." Incorrectly entering codes—especially for Call Forwarding or Do Not Disturb—can cause you to miss critical calls or accidentally "break" your expected call routing. If you are ever unsure, please contact your IT administrator for assistance.
## 1. Call Forwarding (Managing Your Reachability)
Whether you are headed to a meeting or out for the day, these codes ensure your callers reach the right place.
Feature | Code | How to use it |
Forward All Calls | *72 | Activation: Redirects all incoming calls to another number. Type *72 + [Number] + #. |
Stop All Forwarding | *73 | Deactivation: Disables "Always" forwarding and rings your desk again. |
Always to Voicemail | *21 | Sends all calls directly to your voicemail. Dial *21 + [Extension] to send to a specific person. |
Forward if Busy | *90 | Redirects calls only when you are already on another call. |
Forward if No Answer | *92 | Redirects calls if you do not pick up your phone. |
Offline (In Office) | *94 | Forwards calls if your phone loses internet connection during work hours. |
Offline (After Hours) | *81 | Forwards calls if your phone is offline outside of office hours. |
## 2. Call Handling & Teamwork
Use these features to move calls around the office or "park" them for later retrieval.
Call Transfer (*54): Dial *54 + [Number] + # to move an active call to another extension or external number.
Direct to Voicemail (*55): To send a caller straight to a colleague’s mailbox without ringing their desk, press Transfer then dial *55 + [Extension].
Call Park (*68): This "holds" a call in the cloud. Dial *68 + [Extension] to park it there for someone else to pick up.

Call Flip (*11): Seamlessly move a call from your desk phone to your mobile app by dialing *11.
Call Pickup (*97 or 98): Hear a coworker’s phone ringing? Dial 97 + [Extension] to answer it from your own desk.
## 3. Privacy & Outbound Identity

Set Your Default ID (*64): Dial *64 + [Number] to set the specific phone number you want customers to see when you call them.
## 4. Call Recording & Monitoring
For quality assurance and record-keeping, you can manage recordings manually if authorized.
Start/Stop Recording: Use 44 to begin recording and 45 to end it.
Pause/Resume: Use 48 to pause a recording (for privacy during sensitive info) and 49 to resume.
Silent Monitoring (*63): Authorized supervisors can dial *63 + [Extension] to listen in on a live conversation.

Agent Status: Ready: Dial 36 when you are ready to take queue calls.

## 6. Essential Shortcuts
Access Voicemail (*57): Dial this and enter your PIN to check your messages.
Redial (*66): Quickly call the last person you dialed.
Call Return (*69): Call back the last person who called you.
