Right click BSC, and choose Customize Call Processing..., then configure as below:
In above example, upon receiving the terminated call, device will display "12" as calling party number. IMPORTANT: the CHARi field requires ASCII format.
If we configure RECORD_TYPE to other values, device will display other information upon receiving mobile terminated call. e.g. RECORD_TYPE = 0x10 means device should display "Extended Display" information.
