Shawn, thanks for the help. Either I am still missing something, or Odoo is missing something. When I am on a lead and click on "Schedule/Log Calls", I am then given no option to Schedule a call. I have to click on Sales>Phone Calls>Scheduled Calls, click create, and now since I am no longer associated with the Lead, I have to search for the lead again to associate it. Also, I still don't have a meeting request button. I tried on both my premise based system and Odoo Demo/SaaS and same thing.

In Odoo 8, The schedule and log calls menus are essentially the same table, just different states. When you click on 'Schedule/Log calls', on the form view that loads up, you can choose the state (Confirmed,Cancelled,Pending,Done). You can change the state in this form by just clicking the state you want. I think Confirmed or Pending calls will be shown in the scheduled calls menu.

Also the meeting request button is present right next to Schedule/Log Calls in the lead form view. As far as I know, you needn't do anything additional to see it.

EDIT:

Have a look at this, and sorry for the terrible art work !
