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
-
Log in to your Zonitel Office Portal.
-
Go to Numbers → Extensions.
-
Find the extension you want to update.
-
Click the extension (or Edit under Actions) to open settings.
-
Locate the field/selection.
-
Choose the business number you want to display when this extension calls out.
- Click Save.
Quick test (recommended)
-
From that extension, place an outbound call to your cell phone.
-
Confirm the caller ID shows the new outbound number.
-
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.
