User A
has the internal number 323. Two numbers are assigned to this user. One is a London number (+44 20 1234-323) and the other is a Manchester number (+44 161 6623-14). This user can therefore always be contacted via his Manchester number, even when he is in London.
If the subscriber is in Dortmund but calls a number in Munich, his call can be routed via the gateway (trunk) in Munich and thus his call number in Munich (49 89 6623-14) is signaled to the caller.
Other internal callers dialing from anywhere in the company can contact him at any time via his internal number (323).
