The Rate Table - Override feature allows you to group 2 or more Rate Tables together and instruct CDR2Cloud which Rate Table to use for a customer, based on the Rate Tables Override value and the Override value of the CDR record. This feature us extremely useful when your CDR file contains billing records for many different services.
EXAMPLE
Challenge
You are a VoIP Retailer and your VoIP Wholesaler (Provider) provides you with 3 different services which you resell to your customers. They are SMS, MMS and VOICE services. Your VoIP Provider provides you with CDR files on a timely basis which you in turn use for billing your customers, however each CDR file contains CDR records for all 3 services as follows:

You charge your customers 3 different rates for SMS, MMS and VOICE, as follows:
| Cost | Destination Number | |
|---|---|---|
| VOICE | 80 cents @ minute (0.80) | 353838000001 |
| MMS | 70 cents @ minute (0.70) | 353838000001 |
| SMS | 60 cents @ minue (0.60) | 353838000001 |
You however can only assign one Rate Table to a Customer record, so you need a solution that will allow you to define 3 separate Rate Tables, one each for SMS, MMS and VOICE and allow the CDR2 Cloud system to use the applicable table depending on the type of service consumed by your customer.
Solution
You define 4 separate Rate Tables each having the same name but different Override expression as follows:
| Purpose | Rate Table Name | Override Regex | Notes |
|---|---|---|---|
| For billing VOICE services | Customer Rates | (VOICE) | CDR2Cloud will use this Rate Table for billing all Voice services for customers assigned to the "Customer Rates" Rate Table |
| For billing MMS services | Customer Rates | (MMS) | CDR2Cloud will use this Rate Table for billing all MMS services for customers assigned to the "Customer Rates" Rate Table |
| For billing SMS services | Customer Rates | (SMS) | CDR2Cloud will use this Rate Table for billing all SMS services for customers assigned to the "Customer Rates" Rate Table |
| For billing Other services | Customer Rates | CDR2Cloud will use this Rate Table for billing all other services for customers assigned to the "Customer Rates" Rate Table |
When creating multiple Rate Tables for a Group you can use the Rate Table Copy feature to quickly duplicate the Rate Table but remember to change the Rates.
Note that when using the Rate Table Override feature to create a group of Rate Table there must always one Rate Table with the same name and an empty Override ReGex.
Lastly you will assign the Customer Rates Rate Table to you customer(s) as shown below
