15 Numbers and Number Mappings
A flexible number concept, which supports distributed locations
The
number mapping explained in this chapter describes the mapping of internal numbers for a user to external call numbers.
Number mapping should not be confused with the number replacement which can be defined on a trunk group. Number replacement specifies how numbers (number ranges) can be replaced by other numbers/ranges (
8.7.1 Defining call number substitutions for a trunk group).
In this context, please note the following definitions:
Forwardings are in relation to a trunk group and establish whether a call via this trunk group can fundamentally leave the SwyxWare installation (
8.7 Forwarding and number substitution). The
call permission for a user or a trunk group defines whether a call has the right to be made via this trunk group (
8.2 Edit trunk groups).
