The entry of the location is mandatory for the first commissioning. With the country setting, the country code of the respective country is automatically adopted. Depending on this first location entry, also the emergency numbers of this country are adopted by the PBX.

If the location of individual accounts is different than the location of the PBX, these locations must be added and assigned to the accounts. By including a user in the call distribution of an account, a location is also assigned to the user. If several accounts have been assigned to a user in the call distribution, the location is assigned via the number presentation.

If the location of individual telephones is different than the registered locations, these locations must be added and assigned to the telephones. Softphones (also called soft clients) are very often not permanently bound to a location and are therefore created without a location by default.

The correctly assigned location is necessary, among other things, so that the PBX can properly initiate an emergency call.

When dialling a number without an area code, the phone's location (if set) or alternatively the user's location is dialled in advance. The PBX location is only used here if no other location can be identified.
