IMG 1010 - Route List Percentage based routing
Overview:
Within a Routing List are multiple Channel Groups. As a call comes in to the IMG, The Route List uses the selection in the "Hunting Options" field to determine the order in which each Channel Group is selected. The current selections are Sequential, Round Robin, and LRU (Least Recently Used). Feature 0846 adds a fourth option into the Hunting Options field. The newest Option is a percentage based option. When the percentage based option is selected each Channel Group within the Routing List can be assigned a percentage. With the Percent Based Routing the calls are allocated based on what percentage the Channel Group is given. For example: Channel Group A is given a percentage of 50%, Channel Group B is given a percentage of 50%. With this example, half the calls will be allocated to Channel Group A and half will be allocated to Channel Group B. See below for more information.

Based Route List will be created beneath this object. See IMG 1010 - Route Lists for more information on this object.
Right Click on Route Lists and select New Route List. A Route List like below will appear. Enter a name for the Route List and select "Percent" as shown below. In this example the Route List was named ' Percent_Based_Route_List'. See IMG 1010 - Route List for more information on configuring this object.
Right Click on the Route List just created and select New Channel Group.
Select a channel group from drop down menu in the Group Name field and then select a percentage between 0-100 from the Percentage Allocation field.
In the screen capture above, Channel Group "ChGrp_SS7 - ID:0" will be allocated 25% of the calls. Continue creating Channel Groups under the Route List object until all Channel Group objects created for this feature have been allocated a percentage. In this example each of the four channel groups will be allocated 25%. See IMG 1010 - Channel Group - Route List Entry for more information.
...
At this point, all Channel Groups have been allocated a percentage. The Percent Based Route List has been created,
Go back to the Route Table entry under RT1 and in the Outgoing Route List field select the Route Table just created. See screen capture below.
Configure Incoming Channel Group to point to Route Table created above:
...
The total percentage for all channel groups in the Percent Based Route List must equal 100%. If the allocation does not equal 100%, an error message will appear allowing the user to continue editing or delete the object.
A Channel Group configured with 0% allocation will not be included in the calculation when IMG determines which channel group to send call to.
Percent based routing is applicable per Route List. Multiple Route Lists can be configured and each could have a different hunting method.
A compatibility issue arises when the GCEMS application being used supports the Percent Based Routing Feature and the IMG system software being used does not. In this situation the GCEMS application is trying to send information to the IMG which it does not understand. An error message "Unknown reorder method in Instruction List" will appear.
A compatibility issue arises when an older GCEMS application is utilized that DOES NOT support the Percent Based Routing and the configuration file being utilized was created on a GCEMS application that supports Percent Based Routing. In this scenario the GCEMS doesn't understand the configuration and the Percent Based Routing will not get applied/configured.
The percentage allocation of a specific channel group may not match the allocation exactly. When used over time the distribution of calls will converge to the configured allocation.
Within ClientView is an Object Table Tab. This tab displays the percent allocation to each channel group as shown below.
