- Configure the adapter modules to call the number range.
---------------------------------------------------------------------------------------------
- Create the number range in B2B home.
Go to B2B home > Go to NRO > Create number Range
Provide the essential parameters such as NRO name, minimum value, maximum value, and number range length.
- Call the number range in message mapping and map the value to the required target field.
Number range should be mapped to the target field as below
"$B2B_UEBNR<Number Range Name>$B2B_END_UEBNR".
In this example "$B2B_UEBNROTC377_BSN02$B2B_END_UEBNR".
- Configure the adapter modules to call the number range.
In the receiver communication channel include the module "TransmissionNumberModule" with module key "NRO".
