To use Talk, you'll need to buy a phone number from us. You can purchase this number from directly within Talk. If you already have a support telephone number, and want to keep using it, you can forward calls from your support number to the Zendesk Talk number.

Adding an external number for outbound calls
External numbers for outbound calls is a feature only available on the Talk Professional and Enterprise plans. To add an external number, you must have international calling enabled. To enable international calling, contact customer support. New external numbers are associated with your default brand at the time the number is added.
When agents place outbound calls, the Talk number selected in the call console appears as the caller ID. If you have an outside number that you'd like to appear for caller ID instead, you can add it as an external number. This does not route incoming calls to the external number into Talk. It only allows you to place outbound calls using the external number.
For details on configuring using an external number for your outbound caller ID, see Standardizing your outbound caller ID.
- In Admin Center, click the Channels icon (
) in the sidebar, then select Talk and email > Talk.
- Click the Lines tab.
- Click Add line > Add an external number.
- Enter the external number in the window that appears and click Call to receive
a verification code.
- Enter the verification code from the screen on your phone to verify the external
number.
The external number now appears in your list of phone lines.
Forwarding incoming calls from an existing number to Talk
If you want to keep using an existing telephone number for support, you can forward the calls to a Talk number. If you have a US-based number with another carrier, you also have the option of porting the number to Twilio (our voice service provider) to use as your Talk number.
To forward calls
- Set up a Talk number as described in the section above.
- Ask your telephone service provider to forward calls to the Talk number.
Make sure to check with your existing provider about passing the inbound caller ID to your Talk number.
To port an existing number to Talk
Zendesk let's you move or "port" your existing phone number to Zendesk Talk for many countries. Bear in mind that this process might take some time, so factor that into your plans. To get started, see Porting numbers into Zendesk Talk.
Adding a local business address
For some locales, you'll need to add a local business address.
If you're adding a new number from one of these locales, you'll be prompted to enter the address while purchasing the number (see Adding a new line,)
If you're using an existing number that requires an address, you can enter it in the Talk channel settings.
For a full list of address and documentation requirements for Talk numbers, see Zendesk Talk and Zendesk Text number address requirements.
- In Admin Center, click the Channels icon (
) in the sidebar, then select Talk and email > Talk.
- Click the Addresses tab.
- Click add address.
- Enter your address details.
- Click Save.

Hi - I'm trying to add a new number to our Talk package, but can't find the Lines tab on the Talk - Admin page.

Hey Chris,
Can you confirm you're an admin on the account or have the ability to make subscription changes? I did some testing on my end and the option to add an additional line does show up for me. I'm wondering if it's an access issue? Is another admin on the account able to see this option?
Let me know!
Are there any plans to allow us to choose the Hold greeting for external phone numbers? Currently it plays the "Default" greeting and I cannot find a way to change it.
Forwarding vs porting: which is better? What are the pros and cons?
Can a number purchased in Zendesk be ported OUT?
Hello! My team is interested in adding an external number to our Zendesk Talk lines so we can have all staff place outbound calls to our program participants from a single phone number. Two quick questions I had:
It would be nice to have a way to delegate agent or group access to certain external numbers. Is there a plan to add this in the future?
The toll free number was deleted. How could I add the number to zendesk again?
