Show service numbers

[mschwrdtnr]

Is your feature request related to a problem? Please describe.
There is no possibility to see the service numbers for mail department, facility management etc..

Describe the solution you'd like
A new card on the information-page with space for different important buttons to different sites. One button of this card is "Company Service-Number". A dialog will open a list with all service numbers which can directly called (interactive-attrbiute-field.component should be used).
