PBX Dial Codes – Advanced Usage

Dial codes are key/number combinations used to access functions within the phone system directly from your phone. Below are some of the most useful codes – for a full list – Click Here.


If you wish to “park” a call and then pick up the call from another extension, you can do so by parking the call in the “Parking orbit”. Alternatively, you can use the “Shared Parking Orbit”.

To park a call
• On an established call to your extension start the “blind transfer procedure” and transfer the call to *0[0-9]. For example, *01 will place the call in the parking orbit 1, *02 will place the call in the parking orbit 2, etc.

To pick up a parked call
• Dial *10 to *19 where the 0 – 9 is the park orbit number the call was parked in. For example, calling *11 will pick up any calls parked in parking orbit 1, *12 will pick up any calls parked in parking orbit 2, etc.

Parking Multiple Calls
• Parking orbits support parking of multiple calls in the same orbit. Therefore, when unparking, you can add the extension number from which the call was parked to be sure that you un-park the correct call.
• For example, if extension 100 parked a call in park 0, this call can be picked up by another extension by keying in *10100. Omitting the extension number otherwise un-parks the longest parked call in the particular orbit.

Pickup a call
• If you hear a particular extension ringing, and you know that the owner of that extension is not able to take the call, you can take the call by using the “Call Pickup” feature. To do this, type:
• *20*
• This will redirect the active call from the specified extension to your extension. You can also retrieve a call from a ringing extension without specifying the extension number. To do this, type *20* followed by the send key. This will redirect the longest ringing call to your extension.

Change Profile Status
• You can change your status by using the dial code in the following manner: *3[0-4]. 0 is “Available”, 1 is “Away”, 2 is “Do not Disturb”, 3 is “Custom 1” and 4 is “Custom 2”.
For example, dialing *31 from extension 100, will change the profile status of extension 100 to Away

Connect to Voicemail of extension
• To leave a message in the Voicemail box of a particular Extension: Dial *4.
• For example, *4100, will leave a voicemail message in the voicemail box of extension 100.


The intercom feature allows you to make an announcement to another extension without requiring the other party to pick up the handset. The message will be played via the other phone’s speaker. The audio is two way, and the called party can respond immediately without picking up the handset. Paging is also a group right which must be assigned to an extension. The extension can then use paging within its extension group. If the right is missing, paging calls will be converted to regular calls.

Start an Intercom Call
• Prefix the extension you wish to call with *9, followed by the extension. For example, to make an intercom call to extension 100 you should dial: *9100
• If you want your phone to Auto-answer (only applicable for legacy devices) you need to configure a dial code in the PBX Settings → Advanced → Dial Codes tab. This Dial code must be unique and must not conflict with any of the other dial codes.
