I have a requirement to record the details of calls initiated by Ring Out upon completion of the call. I'm successfully polling the Ring Out Status until the call is finished, but I can't find a way to then query for the User Call Record for the completed Ring Out. Is there a way to get the Session Id for a Ring Out call which can be used to retrieve the User Call Record and/or query for a User Call Record using a Ring Out Id? Better yet, can I create a subscription which will notify my service when a Ring Out call is completed?
