Note: Adding a service is available only to primary users in an account. To add a service to a user in your account, login to your account and go to "Account Management -> Users". A list of all users in your account is displayed:
To add inbound service to the above test-admin-user, for example, click on the 'Add' link in the 'Inbound Queue' column. You will be presented with a choice of countries and area codes in which to set up an inbound number for this user. Once selected, you will be returned to this screen, where the 'Add' link will change to 'In cart', as in the following image.
Similarly, if you need to add outbound service to the above test-inbound user, click on the 'Add' link in the 'Outbound Queue' column. You will be presented with a dialog box to enter this user's email address. Once selected, you will be returned to the user list screen, where the 'Add' link will change to 'In cart'.
Now you need to check out. Click the 'In cart' link and follow the screens through the checkout process.
