Extension Number Protection

Use

Users can maintain the extension number of each work center. The system does not check whether the number is actually that of the telephone belonging to the work center. If users assign themselves the number of a different telephone, calls directed to this number are not put through to their telephones but these users can display the call data on their screens. To prevent users from assigning themselves a sensitive telephone number (that of a superior, for example), administrators can protect extension numbers. This can happen as follows:

All extension numbers are allowed. Certain numbers are disallowed for all users, with the exception of certain users.

Example

Sales and distribution department

Telephone integration is created for the sales and distribution department of a company. It is wise to prevent users from assigning themselves the telephone number of the sales director. The sales director has user name Meier and extension 4343.
All extension numbers are disallowed. Certain numbers are allowed for specific users.

Example

Telemarketing

Telephone integration is created for a group of two employees and 20 temporary employees for telemarketing. The employees Becker and Klein have their own work centers with telephone numbers 1818 and 1919. Four work centers with the numbers 2323, 2424, 2525 and 2626 are available for the temporary employees. You want the temporary employees to be able to assign themselves any one of these four numbers but to be prevented from assigning themselves another telephone number.

Process

Extension number protection is defined for each site and then applies to all telephony servers assigned to the site. The standard setting allows all numbers for all users. You can restrict the authorizations by performing the following steps:

Step	Description
Define rule	Allow or disallow all (other) numbers for all users
Define general exceptions	Exclude individual numbers from the rule (disallow or allow them for all users)
Define user-specific exceptions	Allow numbers for certain users only

SAPphone provides a search function for checking existing extension number protection. This enables the extension number authorizations to be queried for each user or for each telephony server.
