5.3.13 Routing of Incoming Calls Screen
Call routing in the system is described in the introduction section of this chapter. Assignment
of phone numbers for routing calls between D channels is done from the routing subscreen.
Figure 5-20 shows the ISDN routing subscreen. It is accessed from the D channel
configuration screen by pressing “o” (lowercase letter o).
Figure 5-20. Routing Numbers Screen
Each D channel may be assigned two ten-digit phone numbers to be used for routing calls
addressed to those phone numbers. The use of the wild card letter “x” means any digit will
match. Note that D channel routing occurs only after all attempts to route a call to an HSU port
are unsuccessful.
If local routing is disabled (Route Local = no), any call coming into the system on a network
side (i.e., local) D channel will be routed only to a user side D channel based on the called
number. Even if the called number matches, such a call will never be routed to an HSU port
or a network side D channel when local routing is disabled.
The routing table should always contain the default number "xxxxxxxxxx" (10 Xs) to make
sure that all dialed numbers are routed to the network.
