Logic:
- Check the Personal Whitelist, if the number is in the whitelist, proceed to call
- Else check Company Whitelist, if the number is in the whitelist, proceed to call
- Else check the Company Blacklist, if the number is on the blacklist, block the call
- Else if the user has a DNC license, check DNC, if the number is in DNC, follow the DNC configuration (Block/Prompt/Allow).
A customer have a DNC number (+6512345678) but the customer willingly allow the company to call to the DNC number => The company will add the DNC (+6512345678) to the Company Whitelist so that the company can call to the customer but block the call to other DNC number.
