Scheduling Call Back Reminders

[Buffy]

Has anyone found a workaround to where you can schedule call back reminders for customers? What I am looking for is prior to hanging up with the customer you can click on the call and set a reminder to call them back either later that day or another day and then there would be a popup and/or a email to the user to remind them to call the customer back.

What do you want it to do when it is time to remind you? Send an email? Automatically dial provided your extension is available? Pop a web page listing the call-backs scheduled for the day?
