  • T.x: Tasks
  • C.x: Chat

4.2 Rectification (Art. 16 GDPR)

In ProCall Enterprise, contact details are managed centrally and can therefore be changed centrally. Any changes to personal data are then effective throughout the software. Please refer to 4.1.2 Categories of personal data that are processed to find out which personal data can be changed in the software. You will find the corresponding correction option in the UCServer administration:

Sample screenshot: UCServer Administration – User management – User/Modification of personal data

4.3 Objection

4.3.1 4.3.1 Erasure/Pseudonymization (Art. 17 GDPR)

Pseudonymisation is currently not planned in ProCall Enterprise. Individual users or a selection of users can be deleted via the UCServer administration:

Sample screenshot: UCServer Administration – User management – User/Deleting users

4.3.2 Restriction of processing (Art. 18(3) GDPR) 

ProCall Enterprise offers a number of ways to restrict the processing of personal data.
These are described in detail below.

4.3.2.1 Journal

The data in the journal databases can only be viewed by the administrator. Administrator access is necessary for problem analysis and statistical evaluation.

The logging of data for private calls is carried out according to rules that can be configured.

The user can mark calls as private. Lines can generally be marked as private.

Selected telephone lines/extensions can be excluded from logging.

4.3.2.2 Presence states

Presence states or a change history of presence states are not logged. A possibility for the evaluation of presence states is not provided.

In the sense of an implementation of individual agreements, the exchange of presence-relevant information can be configured in a differentiated way.

The establishment of the lowest common denominator on the subject of presence within an organization can be done on three levels:
1. Global
2. Group
3. User
The rights system is additive, that is, if a right is assigned at a higher level, it cannot be removed at a lower level.
The presence state "Inactive" is displayed on a workstation PC or smartphone app due to "inactivity" and can be deactivated centrally/server-side. You can find the configuration in the UCServer administration in settings under User Administration Profiles.

4.3.2.3 Telephone function "Hands-free mode“

If the telephone system’s CSTA interface provides the function "Switch to hands-free mode", this feature can be switched off via a compatible estos ECSTA middleware driver if necessary.

4.3.2.4 Telephone function "Switch-on function

"Switch-on" functions of telephone systems are generally not supported by the estos ECSTA middleware drivers.

4.3.2.5 Telephone function "Softphone conference“

An attention tone is played when entering and leaving a conference. 

4.3.2.6 Phone function "Prevent phone calls via TAPI".

Prevents calls from being made on the TAPI line. Calls can only be made via softphone. This ensures that employees cannot control their desk phone/end device in the office from a remote location (e.g. home office). This is to prevent, for example, that an incoming call is accidentally accepted on the TAPI line and other participants in the office room can accidentally or intentionally listen to a telephone conversation and possibly data of the caller.

4.3.2.7 Authorization levels

Users themselves can control what selected (contact) details and actions a ProCall Enterprise user may view and perform via global authorization levels:

  • System-wide authorizations:
    If authorization is granted on a system-wide basis, it applies to all users of the system. These rights are assigned by the administrator. 
  • Authorizations assigned to User Groups:
    If authorization is granted for groups, it applies to all users who are members of this group. These rights are assigned by the administrator.
  • Authorizations assigned by the user:
    Each user can assign individual authorizations to other users. These permissions can also be viewed and modified by the administrator.

The following authorization levels can be used to restrict the processing of personal data by ProCall Enterprise users as follows:
