The PBX can manage telephones sited at different locations. Telephones that are not in the same location as the PBX must be configured as external extensions and assigned to a location. The correctly assigned location is necessary, among other things, so that the PBX can properly initiate an emergency call.

In order to be able to securely connect remote devices to the PBX, the PBX offers an integrated OpenVPN server.

If the CLIP no screening function is available for the account, and more than one location is involved, the phone number that is to be transferred can be freely assigned, independent of the connection in use.
