Creating patterns in the Call Routing Table gives a possibility to establish a direct connection to the destination or to use a SIP server to route calls through it.
The Call Routing Table lists manually created routing patterns with their parameters (pattern number, state, routing and inbound caller settings, RTP Proxy and Date/Time period settings, metric and description), as well as automatically created and undeletable patterns created from the System Configuration Wizard.
The alternating Show Detailed View and Show Brief View buttons are used to display entries in the Call Routing table in detailed and brief views correspondingly. The brief view displays the most important settings of the routing rules. The detailed view displays all settings of the routing rules as they are configured in the Call Routing Wizard.
The alternating Hide disabled records and Show all records buttons are used to respectively hide or show disabled records in the Call Routing table. The system does not consider the disabled records when parsing the table for the call route.
An "invalid" is displayed beside the E1/T1 routing pattern if the E1/T1 Trunk Settings (E1/T1 interface type, signaling type, etc.) have been changed since creating the corresponding route. Invalid E1/T1 patterns will not take effect.
If the route has an Authentication or an Authentication&Accounting selected from the AAA Required checkbox group, it will have a link to the Users List in the Call Routing table. Users List page contains a list of authorized users defined from the Local AAA Table, and gives a possibility to enable/disable authentication of each user for the particular route.
Since Call Routing Table can have multiple entries which could match to the same pattern, the table will be internally rearranged according to the rules in the following consequence:
the pattern matching best to the Best Matching Algorithm will have the higher position in the rearranged list,
if multiple patterns equally match to the Best Matching Algorithm, the pattern with the lower Metric will get the higher position in the rearranged list,
if the multiple patterns with the same Metric have been matched to the Best Matching Algorithm, the pattern in the higher position in the table will get the higher position in the rearranged list.
The pattern in the highest position of the internally rearranged list will be considered as a preferred one. Next and any consecutive matching patterns will be used, if the destination refused the call due to the configured Fail Reason.
Enable/Disable functional buttons are used to enable/disable the selected route(s). Disabled routes will take no effect while enabled routes will be parsed when initiating routing calls. State column in the Call Routing Table displays the current state of the routes (enabled/disabled).
Edit opens the page Edit Entry to modify routing patterns.
Duplicate is used to create a routing pattern with the settings of an exiting one.This is to avoid configuring a new routing entry completely by duplicating an existing entry with different settings. To use the Duplicate button only one record may be selected, otherwise an error will occur: "One row should be selected". The Duplicate button opens the Call Routing Wizard where all fields except the Pattern field are already filled in. Pattern for the new route will be required anyway.
Delete removes the selected routing patterns and their settings from the
Call routing table.
Select all selects all records in the table.
Inverse selection inverses the current selection (if no records are selected, clicking on inverse selection will check all records).
Move Up and Move Down are used to move the Call routing patterns one
row up or down within the Call routing table. The sequence of the routing patterns is important
as the table is scanned top down and the first suiting pattern is used to
define the routing path.
Move To button is used to move the selected entry to some other position in the Call Routing Table which will increase/decrease the selected pattern's priority.
