good afternoon, I need help to set up the Siemens Hicom 300 PBX so that from an internal number, such as 4001, you can dial directly to No. 911 (emergency).
Research on setting up this type of PBX and the truth that I did not find much, any suggestions, ideas that will allow me to begin to understand the logic of this type of PBX is welcome.
