How do I see the details for each phone call I have made?

Yes, you can since the CRM saves a call record for every call you have made. 

• You can see the list of all the calls you have made in the List View screen of the Phone Calls module. (Essentials > Conversations > Phone Calls List View screen)
  • You can display phone call logs by accessing existing lists or creating a customized list of your own. For example,
    • All Phone Calls - for all calls
    • Missed Calls - those calls that you have missed
  • You can create your own lists on the Create New List page by,
    • Add List Information.
    • Choose List Conditions.
    • Share your lists with other users by entering their names and roles.
    • Saving the list.
• You can see the details of each call record by clicking on the required record in the List View.
