Add and Manage Outbound Prefix

An outbound prefix is a saved dialing code, such as a country code, an area code, or an international access code, that you can attach to an external number before placing the call. Instead of typing the same leading digits every time, you store the prefix once and pick it from a list when you dial. This page walks through creating, updating, and removing outbound prefixes in the Cloud Voice App.

Add an outbound prefix

Your administrator may already have assigned you one or more outbound prefixes that you can apply to external numbers. When none of the assigned prefixes fit the call you want to make, you can create your own.

Caution

Before relying on a custom prefix, confirm with your administrator that the prefix is permitted on the server. A prefix the server does not accept will not route your call.

1. On the Calls page, tap your account in the top-left corner.
2. Open Settings > Advanced > Outbound Prefix.
3. Create the prefix:
   1. Tap the add icon () in the top-right corner.
   2. In the Prefix Name field, type a label that helps you recognize the prefix later.
   3. In the Prefix Number field, type the digits to prepend.
   4. Tap Save in the top-right corner.

Tip

Give each prefix a name that names its destination, for example “UK (+44)” or “Long distance (1)”, so you can pick the right one at a glance while dialing.

To apply a saved prefix when placing a call, press and hold the call button () next to the number, tap Dial through PBX, then choose the prefix you want.

Note

PBX (Private Branch Exchange) is the phone system that handles your calls. Dial through PBX sends the call through Cloud Voice rather than your phone’s own dialer, which is what lets the saved prefix be added before the number goes out.

The Cloud Voice App attaches the chosen prefix to the number and dials the combined result.

Edit an outbound prefix

1. On the Calls page, tap your account in the top-left corner.
2. Open Settings > Advanced > Outbound Prefix.
3. Update the prefix:
   1. Tap the prefix you want to change.
   2. Adjust the prefix name, the prefix number, or both.
   3. Tap Save in the top-right corner.

Delete an outbound prefix

1. On the Calls page, tap your account in the top-left corner.
2. Open Settings > Advanced > Outbound Prefix.
3. Remove the prefix:
   1. Press and hold the prefix you no longer need.
   2. In the pop-up, tap Delete.
