Creating routes
Routing table rules
The routing engine starts at the top of the routing table and searches for the first
pattern to match both the calling/from and called/to patterns for the appropriate
incoming call type. The first routing table entry whose To Incoming and From
Incoming regular expressions match the incoming destination and originating
number determines how the call is routed. For transfer mode, the pattern only needs
to match on the transfer to address.
Because the routing engine starts the search at the top of the table, the first rule in
the table is the highest priority and the last rule is the lowest priority. List matches
for more specific patterns before matches for less specific patterns within a particular
incoming call type (tel or sip) in the table.
Each call must match a rule in the routing table. Calls that do not match a routing
table rule are rejected by default. For more information, see
