Caller group

A caller group is a user-specific classification of the calling A subscribers in telecommunications . The classification can be set by the B-subscriber (recipient) on a device-specific basis, but is not available on all telephone terminals. The program function is mainly supported by modern cell phones .

description

Caller groups consist of preset groups, e.g. B. social groups , contractual partners or the like. Depending on the device software, the designation can either be freely selected or is preset at the factory. A specific call signaling (e.g. ringtone ) and / or an associated image is displayed; However, an image is only displayed if the A subscriber is in the device memory (not on the SIM card) is deposited. The call signaling experiences a further restriction with the adjustable filtering of certain groups with regard to the signaling, for example only a vibration alarm occurs for the caller group “family”, while for the caller group “work” a vibration alarm and a loud and noticeable signal tone are activated. The caller groups can also be linked to the user profiles . The call passes through a call for an incoming program logic , for example, the phone number to the phone book memory compares, and the current profile and initiates the predetermined call signaling. Furthermore, it is only possible if calling line identification is active.

sense

The purpose is to inform the B-subscriber about the characteristics of the incoming call. He can decide (according to priority) whether to accept a call. The called party already knows from the ringtone which group is calling and does not have to look at the display. Some telephones support the option to prevent any call signaling when an excluded party calls; Thus, with such a caller group, you can completely ignore hundreds of undesirable participants (e.g. HR manager who creates a group of "fired staff"). The function is therefore used for call management . Which numbers are part of a caller group must be defined in advance.

Delimitation of program logic

On the other hand, the software-based predefinition is very similar, but in principle not a caller group, when A-subscribers call the B-subscriber's device without calling line identification and these calls are rejected or the caller hears the busy tone or is simply not served; a redirection to the mailbox is also conceivable.
