HY POSITION OF ROUTING RULES IN THE TABLE IS IMPORTANT
The Router picks rules in the routing table one by one starting from the topmost.
The Router applies (executes) the routing rule only if all of the below conditions are met:
•
The routing rule is enabled;
•
The source and destination numbers of the call match the respective numbers specified
in the routing rule
•
The rule and the calling party belong to the same group
The Router goes to the next record in the table, if at least one of the above conditions is not met.
Fig. 29 Why position of routing rule in the table matters
Consider the case when the routing rule for egress calls is positioned on the topmost line of the
table (see Fig. 29.) As the destination number condition is always met the Router will send all
calls regardless of the destination number to the gateway intended for traffic leaving the system.
Actually, it will never come to comparing the call destination number against the numbers
defined in the routing records positioned under the rule for outgoing calls.
By this means a routing rule that allows any source and any destination number placed ahead of
all other routing rules in the table makes all other destination numbers, i.e. extensions and
services, unreachable.
Note:
Always position the routing rule based on the regular expression ‘*.’ for the source
and destination numbers on the bottom line of the table.
