Figure 2-27 Illustrative interface for routing configuration

The routing table with 50 rules in capacity provides two functions including digit transformation and
call routing assignment. Here are the general rules applied by OMs when executing the routing table:
1. The routing rules in the table are executed from top to down, and the number matching follows
the principle of minimum & priority matching;
2. When there is no rule matched, the call will be processed as follows:
a) For outbound calls, calls will be routed to SIP proxy;
b) For inbound calls, calls will be routed according to its called party number, and if the
called party number does not exist, 404 will be returned.
3. When matched port is not in idle state, 486 will be returned for FXS port, and 503 will be
returned for FXO port.
4. When domain name is used in rule, DNS must be selected and enabled first.
Rules must be filled out without any blank at the beginning of each line; otherwise the data can't be
validated even if the system prompts successful submit.
The routing table is empty by default. The OM will point a call to the SIP proxy server when there is
no matched rule for the call.
The format of number transformation is
Source Number
For example: "FXS 021 REMOVE 3" means removing the prefix 021 of the called number for calls
from FXS port, where "FXS" is source, "021" is number, and "REMOVE 3" indicates the method of
number transformation.
