Number concept
Every user is assigned a public number.
Conversely, each user and each trunk group is assigned one location as a property. The location property also defines information relating to the number, e.g., country code and area code, as well as the public line access number. Each source of a call (user or trunk) and each destination of a call (user or trunk) can then be related to a location and thus to information about the composition of the number (e.g. country code, local area code, public line access).
