When creating a Route Lists object, first a few individual channel groups must be create to route the call to. Second, create a Route Lists object under the Routing Configuration object. The Route Lists object allows multiple Route List objects to be created under it. Under the Route Lists object, create a Route List object. The Route List object allows multiple Route List Elements to be created under it. Each Route List configured can have up to 20 individual Route List Elements added to it. Once the Route Lists, Route List, and Route List Elements have been configured, they can be used for routing. Create a Route Table and then a Route Table Entry object. Within the Route Table Entry object is a field labeled Route Action Type. This field has a drop down menu that includes Route List as one of its routing options. Select Route List from the drop down menu. Now select the Route List created above from the choices in the drop down menu of the Outgoing Route List field just below the Route Action field. A call that is routed to the Route Table created above will then be routed to the Route List displayed in the Outgoing Route List field and then eventually will be sent out one of the channel groups configured under the Route List Element object.
Field Descriptions
Channel Group Type (Incoming Calls Only)
When a call comes into the IMG 2020 a choice can be made whether to process the call normally or if all TDM circuits are being utilized in the IMG 2020, return a 302 (Moved Temporarily) response back to the originating gateway with information where to redirect the call to. This way the originating gateway can decide what to do with the call. Refer to the IMG 1010 - SIP Redirect IMG Initiated 302 topic for more information on this feature.
