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 5-20shows 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.
