This AMO is used for assigning codes to attendant groups (ATNDGR) for exchange calls, internal calls and universal night answer.
At the same time, in certain cases, it is possible to discriminate between dial plan groups (DPLN) and/or call progress states (CPS) when allocating fixed call codes.
It is also possible to allocate several indial call codes (dial suffices) to one attendant group, e.g. in the case of several companies or corporate divisions (’customers’) subscribing to the same system.
