How to Set an Extension’s Outbound Caller ID (Outbound Number)

Outbound Caller ID controls which business number displays when a specific extension/user places calls. This is useful for multi-location businesses, departments (such as Sales vs. Billing), or agents who should always call out using a specific main number. This guide shows you how to assign an outbound number to an extension and verify that it works—so your calls appear consistent, professional, and recognizable to customers.

✅Step-by-step: Assign an outbound number to an extension

  1. Log in to your Zonitel Office Portal.

  2. Go to Numbers → Extensions.

  3. Find the extension you want to update.

  4. Click the extension (or Edit under Actions) to open settings.

  5. Locate the  field/selection.

  6. Choose the business number you want to display when this extension calls out.

  7. Click Save.

Quick test (recommended)

  1. From that extension, place an outbound call to your cell phone.

  2. Confirm the caller ID shows the new outbound number.

  3. If it doesn’t, log back in and double-check the extension’s outbound selection and save again.

Best practices

  • For best brand recognition, set outbound caller ID to a main business number customers already know.

  • Use different outbound numbers by department (ex: Billing vs Sales) to reduce callbacks to the wrong team.

  • If you have multiple locations, match outbound numbers by location to improve trust and answer rates.

FAQ

Q: Can multiple extensions share the same outbound number?
A: Yes—many extensions can set the same main number for multiple users, so customers always see one consistent caller ID.

Q: Why does my outbound caller ID still show something else?
A: Your account may have global outbound rules, carrier restrictions, or the extension may not be saving the updated outbound number. Support can verify your routing and configuration.

Q: Does this affect SMS?
A: No, outbound caller ID applies to calls only. SMS behavior depends on your messaging configuration and assigned numbers.
