Additional Authorization for Toll Calls

This feature allows you to perform additional verification of outgoing tolls on international calls. Especially in the case of a single phone being shared among multiple users, this feature enables individual accountability on each user’s account. Note that calls between IP Centrex extensions and calls to other IVR applications (e.g. to voicemail) bypass the additional authorization.

 

Below you will find configuration examples for each case:

Example 1. Allow toll calls only after additional authorization

1.      Open the IVR Applications page.

2.      Click the  Add button.

 

 Open the IVR Applications page

 

3.      Fill in the following fields:

·       Application Type – choose Pass-Through IVR.

4.      Click the save Save button.

 

Add an IVR application

 

5.      Click on the application’s name to further configure this IVR application.

 

Select the application

 

6.      To add an access number, click the  Add button.

 

Add an access number

 

7.      On the Access Numbers tab fill in the following field:

·       Access number – Specify the number that the application will check to authenticate a call for an account. For security measures, we recommend that you use alphanumeric characters for the access number (e.g. BA24AB%.)

NOTE:  You can use any combination of digits followed by the obligatory “%” symbol. However, make sure it does not match the E.164 prefix.

8.      Click the save Save button.

 

 

9.      In the IVR Settings tab of the IVR application, select the Authorize Paid Calls check box. This will enable additional authorization for toll calls. The IVR application will request an authentication code.

_Hint_Glasses TIP: The Pass-Through IVR application that runs on the previous-generation Media Server requires that the rating entry with the PortaUM node is present in the product. Therefore, make sure you have added the following rating entry to the product rating list for the product that is assigned to corresponding customer accounts:

·       Node –Your PortaUM® node;

·       ServiceVoice Calls;

·       Tariff – The tariff that contains the destinations to which your customers are allowed to place calls.

 

11.   This configuration requires a credit limit for the customer. If the credit limit has already been set, you may go directly to the Account Info page to continue the configuration, otherwise set a reasonable credit limit for the customer.

12.   On the Account Info page of an account that requires additional authorization, go to the Outgoing Calls section.

13.   In the Call via IVR list click Enabled.

14.   Select the above-created Voice Application and click save Save.

 

 

15.   In the Service Unblock Code field of the Fraud Detection tab specify the authentication code that the account user should input to make a toll call and click save Save.

 

Enable IVR Authentication

Example 2. Shared phone line for individual users

This example shows you the configuration for the following scenario. Customer has a shared phone line, 12121234567, in the office hall. Every office worker has their own authentication code for making toll calls (e.g. 7614, 1027, 5423, etc.).

 

When an employee makes a toll call, they are prompted to enter an additional authentication code (7614, 1027 or 5423) to specifically identify who they are so that calls can be properly authorized against individual accounts and later shown on a combined invoice.

 

When one of the employees makes an outgoing call to another SIP phone within the same IP Centrex environment or makes a toll-free call, the call is then initiated without additional authorization.

 

In this scenario, only the main account, 12121234567, is provisioned on the SIP phone. For user identification, additional accounts should also be created with IDs that include the phone number followed by the # symbol and an authentication code (e.g. 12121234567#7614, 12121234567#1027 or 12121234567#5423, etc.).

1.      This configuration requires a credit limit for the customer. If the credit limit is already set you may go directly to the Account Info page to continue the configuration, otherwise set a reasonable credit limit for the customer.

2.      Repeat steps 1–10 from Example 1.

3.      In the IVR Settings tab of the IVR application, select the Authorize Paid Calls check box. This will enable additional authorization for toll calls; the IVR application will request that the account user should input the authentication code.

4.      Select the Treat Auth Code as Part of Account ID check box and click save_close Save & Close.

 

Configure the IVR settings

 

5.      Go to the Outgoing Calls section of the Account Info page and in the Call via IVR list click Enabled.

6.      Select the above-created Voice Application and click save Save.
