Calling an Employee from Master Data Maintenance 
Procedure
This takes you to the Maintain HR Master Data screen.
A dialog window appears with the employee’s telephone numbers.

The Dial function is only active if the correct settings have been made for the specific work centers.
The system displays the SAPphone dialog box which shows the selected telephone number, country code, name, company, and any relevant notes.

Check that the number in the field next to the telephone number is correctly formatted, ie, that the area code has been recognized and the numbers for an outside line have been added in the case of external calls. You cannot change this number on the SAPphone dialog box. If the number setup is incorrect, even though the telephone number and country indicator are correct, you must check the number changes in the cross-client settings.
The system dials the employee’s telephone number. Directly next to Dial and Close, the Hang up function is displayed, which you can use to end the current call. You can also end the call by replacing the receiver. As with any other phone call, you can put the call through to another number, put it on hold, etc.
Result
You have made a phone call to an employee via the SAP System from HR master data maintenance.
