After scheduling an advisory call, your calls tab should display a confirmation of date, time, and a dial-in information for your call.
You will also receive an email confirmation that provides a link to save the call information to your calendar. We highly recommend this, as it will allow you to 'one click' into your calls on most smartphones.
When it comes time for your call, you'll be able to one click the dial-in and access code from the event.
