+## Collecting OptIn
+
+In order to trigger outbound calls or sms messages from Regal Voice, you must collect the user’s explicit opt-in for those channels along with the user’s phone number.
+There are 2 options for how you can let Regal Voice know a user has opted in. 
+
+Anytime you collect opt-in for sms or voice calls, you can trigger a track event after a user opts in and let the Regal Voice team know what track event is synonymous with opt-in collected (there is no required format for this event). The product will then automatically subscribe users who perform that event. (Note: for Regal Voice to subscribe a user, there must already be a phone provided for that user.)
+
+Alternatively, anytime you collect opt-in for sms or voice calls, you can use an `identify` call to pass that opt-in information to Regal Voice by adding an optIn object.
 
 Below is an example of what an `identify` call would look like for a user who opted into multiple channels (sms and voice calls) at once:

-The `ip` field is required if you are opting in users server side. 
+For the identify method, the `ip` field is required if you are opting in users server side. (If you are opting in users client side, Segment automatically adds ip to the context, so you are not required to add it to the optIn object) 
 
 Make sure to include `timestamp` with the exact time the user opted in. Since traits are [cached](/docs/connections/sources/catalog/libraries/website/javascript/identity/#clearing-traits) and sent with subsequent Identify calls, Regal Voice ignores opt-ins that do not have a `timestamp` date.
