"Change the settings for each of your phones."
Navigate to Phone > Preferences. The page shows [Username]'s preferences with a Save button at the top right.
If your account has multiple phone technologies enabled, you will see tabs across the top. Most users only see one. The available technologies are:
| Tab | When You Use It | Typical Device |
|---|---|---|
| CTIP | Physical phone hardwired to the Abilis unit via a direct cable. | Analogue phone plugged into a CTIP port. |
| CLUS | Multi-site cluster — calls between branch offices connected via VPN. | Inter-office calls. |
| SIP | Most common. Any IP-based phone. | Desk IP phone (Yealink, Grandstream, etc.), PC softphone, Abilisphone app. |
| IAX | IAX protocol — uncommon, used in some Asterisk integrations. | IAX-compatible phones. |
| Abilisphone | The Abilisphone mobile app on your smartphone. | Android/iOS Abilisphone app. |

This controls what happens when someone calls your extension. Three radio-button options (only one active at a time):
| Option | Icon | What Happens | When to Use |
|---|---|---|---|
| No rules | · | Your phone rings normally. No special behaviour. | Normal everyday work. |
| Do not disturb | All incoming calls are immediately rejected. Callers hear a busy tone. | Important meeting where you must not be interrupted. | |
| Call forward | Calls are redirected to another number. When selected, additional fields appear:
— Forward to number — enter the destination (colleague's extension, mobile number, etc.) — Caller ID display — show the Original caller's number or the Forwarder's number — When to forward: Always / On busy / On no answer (set seconds) / On all other causes | Going on holiday, working from home, or covering for a colleague. |

Four checkboxes, each with a small icon:
| Checkbox | Icon | What It Does When Enabled |
|---|---|---|
| Voice Mail | Callers can leave a voice message when you don't answer. The recording is sent to your email. When you tick this, additional options appear: when to activate (Always, On Busy, On No Answer after N seconds, On All Other Causes), email address for recordings, and options to manage custom welcome/goodbye messages. | |
| Voice Recorder | Records your phone calls and sends the recordings to your email. Useful for keeping records of important conversations. | |
| Call Waiting notification | "Audio cue during other calls" — if you are already on a call and someone else calls, you will hear a beep tone. Without this, the second caller simply gets a busy signal. | |
| Make user available for Phone Statistics | Includes your calls in the traffic reports visible on the Statistics tab. If unticked, your calls won't appear in any statistics reports. |

Advanced technical parameters for the selected phone technology. These control low-level protocol behaviour (SIP timers, codec preferences, etc.).
Always click Save (top right) after making any changes on any sub-tab.
