Additional Authorization for Toll Calls
Example 1. Allow toll calls only after additional authorization

Create a Destination
Modify a Customer Tariff
Configure Calls via IVR on Account
Example 2. Shared phone line for individual users
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:
1. Open the IVR Applications page.
2. Click the Add button.
3. Fill in the following fields:
· Name – Specify the IVR application’s name.
· Application Type – Choose Pass-Through IVR.
4. Click the Save button.
5. Click on the application’s name to further configure this IVR application.
6. To add an access number, click the Add button.
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 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.
10. Click Save & Close.
This step is only required if you have not previously defined the required destination. In that case, you will need to create an UMIVRPASS destination for calls to the Pass-Through IVR application.
1. On the navigation menu, select Service catalog, select Rate codes, and then select Destinations.
2. Open the Create a destination panel and fill in the destination information:
· Format – Select Custom from the list.
· Prefix – Type in UMIVRPASS.
· Description – Enter useful information about the service being provided (e.g. Pass-Through IVR application), since this is what your clients will see on their xDR Summary pages.
3. Click Save.
For a customer to be authorized for an outgoing call, they must first call the IVR application. To make this happen, add the UMIVRPASS destination you have just created to the customer tariff.
1. On the customer tariff’s panel, click Rates.
2. On the Add rate panel, select UMIVRPASS in the Destination field. Specify a zero price in the First price and Next price fields.
3. Click Save.
This configuration requires a credit limit for the customer. If you have already set the credit limit for the customer, you may go directly to the Accounts panel to continue the configuration. Otherwise set a reasonable credit limit for the customer.
1. Go to an account that requires additional authorization. On the Edit account panel click Services, then click Service configuration.
2. On the Service configuration panel, select Voice calls and click on the Outgoing calls link.
3. On the Outgoing calls configuration panel, enable the Call via IVR option, then select the above-created Voice application and click Save.
4. On the Fraud detection configuration panel, enable the IVR authentication option, then specify the authentication code that the account user should input to make a toll call. Click Save.
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.).
To set up this functionality follow the instructions below:
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 the Configure an IVR application, Create destination and Modify a customer tariff steps 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.
5. On the account’s panel click Services, then click Service configuration.
6. On the Service configuration panel, select Voice calls and click on the Outgoing calls link.
7. On the Outgoing calls configuration panel, enable the Call via IVR option, then select the above-created Voice application and click Save.
8. Create additional individual accounts that include a phone number followed by the # symbol and an authorization code (e.g. 12121234567#7614) and click Save.
