There are solutions available on the AppExchange like ZFusion that can automatically capture all Webinar & Meeting related data in Salesforce, such as creating new Leads or Contacts (with duplicate checking), detailed registration data like standard questions and custom questions, join and leave time for participants etc. Once installed, data will automatically flow into Salesforce without any need for configuration.
