I am registering for events through webforms. However if people do not leave their phone numbers we cannot contact them. Is there some options I am missing here to make this a mandatory field?

    with a webform in Drupal you have the option to make any field in the form required (mandatory). This setting should be apparent from the list of webform components.

Yes, you can make a field mandatory in a webform. You will need to go under Webform tab of a webform. Click on edit besides the Phone field. On Edit phone scroll down till you see 'VALIDATION'. Check the 'Required' check box and save the form.
