CLI Based Routing
SARVAM UCS offers the facility to detect the calling party's number and name. This is known as Calling Line
Identification.
On the basis of CLI, it is possible to land calls from a particular number on a particular extension or group of
extensions. This is known as CLI Based Routing.
How it works
Let us understand CLI Based Routing with an example.
A, B, C are extensions. D and E are external callers.
Calls made by D are to be landed on A.
Calls made by E are to be landed on B and C.
The CLI of D and E and their corresponding landing destinations should be entered in the CLI Based Routing Table
and CLI Based Routing should be enabled on the desired trunks for each Time Zone.
The system can match the incoming call CLI with the numbers configured in the CLI table in two ways, that is,
Match from last digit of CLI or Match from first digit of CLI.
• If you select Match from last digit of CLI, this is how the call will be routed:
• D calls on a trunk of SARVAM UCS.
• The system checks if CLI Based Routing is enabled on the trunk for the current time zone.
• If CLI Based Routing enabled on the trunk, the system checks the numbers stored in the CLI Based
Routing table.
• D's number is found in the CLI Based Routing Table.
• The system checks the destination number stored against D's CLI.
• A's number is found as the destination extension.
• The system lands the call on A.
• If you select Match from first digit of CLI, this is how the call will be routed:
• D calls on a trunk of SARVAM UCS.
• The system first checks if CLI Based Routing is enabled on the trunk for the current time zone.
• If enabled, the system checks whether the parameter Replace '+' from CLI, is enabled.
• If enabled, the system will replace + sign received in the incoming CLI with the number string
configured in the Replace '+' from CLI with the number string. To know more, see “System
Parameters”.
• Now, the system checks if Incoming CLI Modification is enabled.
• If enabled the system modifies the incoming number according to the parameters configured in the
Incoming CLI Modification. To know more, see “Incoming CLI Modification” in “System Parameters”.
• The system matches the modified number string with the numbers stored in the CLI Based Routing
table.
• D's number is found in the CLI Based Routing Table.
• The system checks the destination number stored against D's CLI.
• A's number is found as the destination extension.
• The system lands the call on A.
If D's number does not exist in the CLI Based Routing Table, the call will be routed according to the incoming
call management logic.
