PINless dialing

PINless dialing service allows users to make cheap long-distance/international calls from their mobile or landline phones without entering a PIN by simply dialing an access number.

When a user signs up for your PINless dialing service, you register their phone number in the system and provide them with the access number they must dial. Then, when the user makes a call, the system recognizes their CLI (ANI), informs the user about their balance and asks them to enter their destination number.

You can enable user access to the service using either of these two ways:

• A user signs up for the service. You register the user’s ANI as the PINless dialing account and provide the user with the service access number to dial;
• A user purchases a PINless dialing calling card. You enable ANI authentication and auto registration options for your Prepaid card calling application. When the user dials their access number for the first time, they are asked to enter their PIN number and offered to register their ANI. From then on, they are only asked to enter their destination, entirely skipping the PIN number entry step.

This document describes how to provide PINless dialing service by creating dedicated PINless dialing accounts.

Let’s say, Amanda Doe signs up for your PINless dialing service. You add her mobile number 16041112222 as a PINless dialing account and provide her with a service access number. When Amanda dials the access number from her mobile, she hears what her current balance is and is asked to enter her destination number. After she dials the destination number, the system informs Amanda about the maximum permitted call duration and connects the call. When the call ends, the system deducts the correct amount from Amanda’s balance.

Also, Amanda is granted access to the self-care portal, so she can keep track of her calls on her own and top up her balance as necessary by using her credit card.

Use this checklist to check off the operations you have completed while performing the system setup according to the instructions in this chapter. Please be sure to perform all of the operations in the order designated (all of the boxes should be checked), otherwise, the service will not work.

If you have just installed the PortaSwitch software or dedicated a new billing environment to configure the services described in this handbook, make sure to first perform the initial configuration of PortaBilling. To do this, use the Initial Configuration of PortaBilling handbook.

A tariff is a single price list for call services. A tariff combines:

• Conditions which are applicable to every call regardless of the called destination.
• Per destination rates.

1. On the navigation menu on the left, select Service catalog and click Tariffs.

   

2. On the Create tariff panel, fill in the tariff details:
   • Name – type a short name for the tariff object; this is the name you will see in the select menus (for example, GlobalNet Termination).
   • Currency – choose the currency in which the vendor charges you.
     The currency for the tariff may be chosen only once, and cannot be changed later.
   • Service – choose Voice Calls here.
   • Applied to – choose Vendor in the Applied to list.
   • Routing – leave the Routing option enabled for this tariff.
3. Click Save.

   

Rates are per-destination prices. Please refer to the Call Billing Parameters section in the PortaBilling Administrator Guide for more details on billing parameters.

Managing rates online is very convenient for maintaining existing rate tables, as well as for reference purposes. In the case of new price lists or major updates, the offline method is better.

1. On the vendor tariff’s panel (GlobalNet Termination), click Rates.
2. On the Add rate panel, fill in the rate details:
   • Destination – select a destination prefix from the list or type it in directly, e.g., 420 for Czech Republic.
     You must create an entry for certain phone prefixes in the Destination register before creating a rate for them in the tariff.
   • Rating mode – select the Flat rate option here. If you want to enter different rates for the peak and off-peak periods, select the Separate peak/off-peak rate option.
   • Route category – you can split your available routes into several categories, such as “High quality,” “Premium,” etc., then create routing plans for your customers. Use the Default route category for now.
   • Preference – the routing priority for the specific destination. 10 is the highest priority, 0 is the lowest (e.g., do not use this destination for routing at all). For now, you can just set all of your vendor rates at preference 5, and the system will organize available routes according to cost (LCR).
   • Huntstop – when enabled, instructs the system to not try any routes with a lower preference.
   • First interval, seconds – type a first billing unit in seconds.
   • Next interval, seconds – type the next billing unit in seconds.
   • First price – type a per minute price for a first interval.
   • Next price – type a per minute price for the next interval.
     Off-peak fields appear only if the Separate peak/off-peak rate rating mode is selected or an off-peak period has already been assigned to this tariff on the General info panel.
   • Effective from – if you want this rate to take effect sometime in the future, you can either type in a date manually, or use the calendar.
     When using the calendar, you can specify that the date you are entering is in a different time zone than your present one. PortaBilling will then automatically adjust the time.
3. Click Save.
4. Repeat these steps if you need to enter more rates.

   

You also can upload rates from a file in .csv, .xls or .xlsx format – please consult the Rate Import handbook for more details.

 Perform the Create Tariff and Enter Rates steps described above until you have created a tariff with the termination costs for each termination partner you have; these tariffs are created as “Applied to: Vendor”.

This step is only required if you have not entered information about your vendors into the system before. Vendors are your termination partners or the providers of incoming toll-free lines and DID numbers.

1. In the left upper corner click  to open the navigation menu.
2. On the navigation menu, select Infrastructure, then select Vendors.
3. On the Create vendor panel, fill in the vendor details:
   • Name – type a short name for the vendor object; this will be used on the web interface (for example, GlobalNet).
   • Currency – choose the currency in which this vendor charges you.
   • Opening balance – this indicates a starting balance for the vendor; the default is zero.
   • Billing period – split period for vendor statistics.
4. Click Save.

   

1. On your vendor’s panel (GlobalNet), click Connections.
2. On the Create connection panel, fill in the connection details:
   • Description – type a descriptive name for this connection. It will be displayed in the list of connections.
   • Service type – select Voice Calls.
   • Type of connections – select SIP.
   • Direction – select To vendor.
   • Tariff – choose the tariff that defines your termination costs for this connection/vendor.
   • Active – use the slider to set this connection as active.
   • Identify gateway by – choose how to identify the gateway: IP, gateway ID or both. Specify the IP address and/or ID of the vendor’s gateway or switch.
3. Click Save.

   

4. Repeat these steps to add more connections to this vendor.

Since the main purpose of this service is to give your customers access to your prepaid application from PSTN (by dialing your access number from their landline or mobile phone), you have to ensure that calls to that access number are delivered properly to your network and then handed over to PortaSIP IVR.

Please refer to the instructions in the Incoming Calls from PSTN section for complete details about how to set up the vendor and the connection.

First you need to define that when a call is made to the access number of your prepaid calling card service, PortaSIP launches the corresponding IVR application for handling the call.

Set up the IVR Application for the virtual PortaBilling environment where you use this application.

1. On the navigation menu, select Infrastructure, then select Voice calls processing and go to Voice applications.
2. On the Create voice application panel, fill in the following fields:
   • Name – specify the IVR application’s name (e.g., PINless dialing).
   • Application type – choose Prepaid card calling.
   • Entry point – type in the number to be dialed by an end user or click the  button to select a DID number from the available DID numbers list. Click the  Add icon to add more Entry points.

     

3. Click Save.

Of course, you can clone multiple entities in order to customize the application parameters (such as IVR languages or whether ANI authorization is performed), according to your requirements.

In order to support PINless dialing, the prepaid application should have the ANI authentication feature enabled. Then if the ANI number of the incoming call matches the ID of an account, this account is the one placing the call (and will be charged when the call is completed). The customer will immediately be asked to enter a destination, skipping the PIN entry step.

1. On the Voice application panel, go to the Authentication, Authorization, Accounting section and select Authentication.
2. On the Authentication panel use a slider to enable ANI authentication feature.

   

   The Manual authentication option must be disabled for this scenario.
3. Click Save.

When you provide both residential VoIP and PINless dialing services, you will have two types of accounts in the system, and the account ID will contain the phone number:

• “Normal” SIP accounts. When someone in your network dials the number, the system will recognize that the call should be delivered to one of the IP phones connected to PortaSwitch – and will never be sent out to the PSTN.
• ANI accounts. The situation here is exactly the opposite: when someone in your network dials this number, the call will be sent out to the PSTN.

In order to avoid confusion between these two types of accounts (which may result in calls being routed improperly) and allow both your administrators and the PortaBilling routing engine to clearly distinguish between ANI accounts and regular SIP accounts, the PINless account role has been introduced.

When you create an account with the PINless account role, PortaBilling automatically adds the suffix ‘@ani’ for your ANI authentication accounts.

For example, if you would like to allow your customer to use his cell phone with ANI 16041112222 for ANI authentication, you would create the PINless account 16041112222@ani for this customer.

You can also set up the ANI translation rule as a regular expression in the ANI translation rule field.

1. On the Voice application panel, go to the Authentication, Authorization, Accounting section and select Translation rules.
2. On the Translation rules panel type s/$/@ani/ in the ANI translation rule field. This will instruct the system to add @ani suffix to the ANI number of the incoming call and search for an ANI@ani account (e.g., 16041112222@ani) for authentication and authorization.
3. Click Save.

Configure in which languages the IVR will communicate with the customer.

1. On the Voice application panel, go to Prompts & notifications and select Language.
2. Click the Select languages button to launch the dialog box for the language selection.

   

3. In the Select languages box, choose the language (or several languages) you wish to use for voice prompts. In this case, the IVR’s first prompt will be the language selection prompt “Please press 1 for English, 2 for Russian, 3 for German, etc.” To choose all languages at once, select the line All available on top. Then click the Select button.

   You can also change the languages order by moving  icon up and down.

   

4. Click Save.

Configure the IVR application to use your brand prompts instead of default ones. Please refer to the How to Configure Custom Brand Prompts section for a detailed configuration description.

See the APPENDIX A.  PortaSIP Media Server IVR Applications Preferences section of the PortaSIP Media Applications Guide to read more about the prepaid card IVR configuration parameters.
