14.7.9.10. Configuration of Default Route if Number did not Match in “HOME
DN” 
In Figure 64
above the dialed number 49897007-xxxxx was sent for a check if there
exists an entry in the OpenScape Voice system. If there is no match,
dialed numbers are checked against this entry.
As default, you should configure the partner OpenScape 4000 system.
But in this example we used as default a different OpenScape Voice system.
