The module Phone Call is used to remind yourself or a coworker to make a call or record that a customer called.
It is a version of While You Were Out - but much more powerful.

The Phone Call module allows to assign the task to multiple employees (Employees field) and associate it with different companies or contacts (Related to) but it is linked to one and only one Customer (which could be a company or contact):

It was not intended to create a list of contacts/companies to call.
This functionality is possible using Premium Module: List Manager

Using this module you can create a list of targets to call (or e-mail or fax) and store notes and history. You can create a list, assign employees responsible to make phone calls and review entire history of their actions.
The module is available in EPESI Store now.
