The snom ONE administration and configuration is managed via a browser-based tool suite. To log in to the administrator tool suite, type the URL of the server into the navigation bar of your web browser and log in.

Finally, in the Trunk ANI field, add the CLI (phone number) for the trunk.
Click Save and the trunk should be ready to make outbound calls.
The screenshot below may assist you in setting up the trunk.
