Personalized cloud PBX calling

This functionality allows cloud PBX users to make toll calls from any SIP phone in the office using their own authorization code (PIN number).

When an office worker makes a call from his colleague’s phone, he is prompted to enter some additional authorization code to identify himself so that this call’s charges are applied to his account. This way a cloud PBX owner can see who actually made the call and who was charged for it.

This functionality prevents service abuse and enables individual accountability for each user’s account.

Consider the following scenario as the configuration example. Customer Smart Calls, Ltd. want their employees to make toll calls only after they enter an authorization code. Let’s say that some of their employees have the following accounts and PIN numbers:

• Rachel – 17785551209 and 4545.
• Mark – 17785551210 and 8989.

When Rachel makes a toll call from Mark’s SIP phone, she is prompted to enter the additional authorization code. She enters her PIN number and the call is put through. When the call ends, PortaBilling applies the charges and creates xDRs for both accounts. Mark’s account is charged for the call to the IVR and Rachel’s account is charged for the toll call. You can see the call records on the account self-care interface or on the account xDR page.

When Rachel makes a call to her colleague Jake or makes a toll-free call, this call is then initiated without additional authorization.

Since toll calls pass through the IVR application in this scenario you must specify the associated number that is identical for all accounts that use this functionality. This associated number is then sent back to the IVR in an authorization confirmation.

For user identification, create aliases for the accounts with IDs that include an account’s associated number (the part of the phone number in our example) followed by the # symbol and an authorization code (e.g., 1778555#4545, 1778555#8989, etc.).

Print this page and use it to check off the operations you have completed while performing the system setup according to the instructions in this chapter.

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