Setting up a wholesale traffic exchange between virtual environments

This handbook explains how to configure wholesale traffic exchange between virtual environments within a PortaSwitch installation.

Service providers often host smaller operators on their PortaSwitch platform. The host provider owns the infrastructure and wholesale vendor contracts, while the hosted operator manages their own customers and services in an isolated tenant environment.

Before setting up traffic exchange between virtual environments, the GlobalNet admin must ensure the following:

1. Users with an admin role are created in the SmartCom tenant environment. These users have limited permissions with no access to other virtual environments and to vendor configuration.
2. The initial PortaBilling configuration is completed in the SmartCom tenant environment.
3. The GlobalNet wholesale environment (including routing plans) is set up for the wholesale traffic exchange.

Before proceeding with the configuration, make sure you have the following information:

• The list of rate codes that cover the SmartCom DID pool.
• The rate sheet that defines GlobalNet termination costs for the traffic sent to SmartCom.
• The rate sheet that defines SmartCom termination costs for the traffic sent to GlobalNet.
• IP address of the SIP cluster in the GlobalNet wholesale environment (70.68.127.185).
• IP address of the PortaSIP cluster in the SmartCom environment (193.168.0.138).
• SmartCom requirements for outgoing traffic routing, if any (routing plan).

This section describes how to configure call termination to and from the SmartCom tenant environment via the GlobalNet wholesale environment.

To provide voice call services to customers, create a product that includes a customer tariff with defined call rates.

This tariff defines the rates for terminating outgoing traffic from SmartCom to external vendors.

1. Navigate to Service catalog > Tariffs.
2. Click + Tariff and fill in the tariff details:
   • Name – type in a short name for the customer tariff; this name will be shown within the system, e.g., “SmartCom outgoing traffic”.
   • Currency – select the currency in which the customer will be charged.
   • Service – select Voice calls.
   • Applied to – select Customer.
   • Managed by – select Administrator only.
   • Define prices – select Per individual rate code.

     

3. Click Save&Edit.
4. Open the Rates panel in the “SmartCom outgoing traffic”.
   You need a rate code to add a rate. Make sure that the necessary rate codes have been added to the system. See more details on how to create rate codes in the Initial configuration of PortaBilling handbook.

You can add rates one by one or upload them from a file. To download the file sample with all the required columns, click Rate download on the toolbar, then open the notifications tab and download. To add a rate manually, click + Add and fill in the rate details:

• Rate code – type in a specific rate code directly or select it from the list.
• Effective from – specify when the rate becomes effective. By default, this parameter is set to “immediately”. If you want this rate to take effect in the future, select “Specific time” and type in the date manually, or select it from the calendar.
• First interval, seconds – specify the first rounding interval in seconds (default is 1 second). This interval defines the minimum duration of the call that is going to be billed. For instance, if the first interval is set to 30 seconds, a call lasting between 1 and 30 seconds will be billed as a 30-second call.
• First price – specify the per-minute price for the first interval.
• Next interval, seconds – specify the next rounding interval in seconds (default is 1 second). This determines how the call duration beyond the initial interval is billed. For example, if the next interval is set to 1 second, any duration beyond the initial interval will be billed in 1-second increments. If you set the first interval to 30 seconds and the next interval to 1 second, and the call lasts for 36 seconds, the customer will be charged for 36 seconds.
• Next price – specify the per-minute price for the next interval.

  

Create a product that will be assigned to the SmartCom account at step 2.4:

1. Navigate to Service catalog > Products.
2. Click + Add and fill in the product details:
   • Name – type in a short name for the product; this name will be used within the system, e.g., “SmartCom wholesale traffic”.
   • Name visible to end users – leave the suggested name as is.
   • Product type – select Main product here.
   • Currency – select the currency that the product will be priced in.
   • Managed by – select Administrator only here, since we are setting up a service without the involvement of resellers.
   • Account default ACL – leave the default Account self-care ACL.
   • Account role – select IPv4 address.

     

3. Click Save.
4. Go to Product > Services and click Add a service to select services included in the product. To provide a voice call service, include the Voice calls.

   

5. Once you save the product details, you need to configure usage charges. On the product’s panel, click Charges, then click Usage charges.
6. Click Add and fill in the required information:
   • Service – select Voice calls.
   • Node – select PortaSIP configured during the initial configuration.
   • Access code – leave this field empty.
   • Tariff – select the “SmartCom outgoing traffic” tariff, created at step 1.1.
   • Overdraft protection – turn on the feature. To configure overdraft protection for this product, consult the Overdraft protection configuration handbook. In short, overdraft protection locks a certain amount of resources for each session. This enables the simultaneous consumption of the same quota across different sessions on various devices.

     

The SmartCom customer can have invoicing enabled to reflect charges for traffic terminated to GlobalNet.

To enable invoice generation, you must first create a template for the invoice layout.

1. Navigate to My company > Templates.

An account authorizes the endpoint from which calls are sent from SmartCom for further termination. Two authorization methods are supported:

• SIP digest authentication – the most secure and robust method.
• IP-based authentication – authorization by the remote gateway or proxy IP address.

This handbook assumes IP-based authentication. In this case, the account ID must match the signaling IP address of the PortaSIP cluster in the tenant environment.

If the gateway supports SIP digest authentication, the account ID can be either an alphanumeric string or the gateway’s IP address.

1. On the customer’s panel, click Accounts / DIDs.
2. On the Accounts tab, click + Account, and on the General tab specify the account’s details:
   • Type – select Credit.

3. Go to the Products tab and select the “SmartCom wholesale traffic” product, created at step 1.2.

   

4. Click Save.

A routing plan defines how calls are routed for specific customers. It lets GlobalNet restrict access to certain vendors or allow only selected vendors in a defined order.

Routing plans are assumed to be already configured in the GlobalNet wholesale environment. If SmartCom requires a specific routing setup, assign the appropriate routing plan to the account. If no custom routing plan is assigned, the system uses least-cost routing, which allows access to all available carriers.

To deliver incoming traffic to numbers hosted by SmartCom, configure SmartCom as a vendor.

This tariff includes rates for terminating incoming traffic to SmartCom. PortaBilling uses these rates to calculate GlobalNet call costs for reconciliation.

1. Log in to the GlobalNet wholesale environment.
2. Navigate to Service catalog > Tariffs.
3. Click + Tariff and fill in the tariff details:
   • Name – specify a descriptive name for the tariff, e.g., “SmartCom wholesale termination”, which will be used within the system.

   • Capacity – specify the maximum number of simultaneous calls the connection can support, e.g., 500.
   • Tech prefix – leave this field empty.

     

3. Click Save.

Since SmartCom is configured as both the vendor and the customer, exclude the SmartCom vendor from the routing list for calls sent from the SmartCom customer to prevent a call termination loop.

1. For this, open SmartCom vendor settings, navigate to General configuration.
2. For the Offset balance with customer option, select SmartCom customer from the list.
3. In the Minimum amount to offset field, specify the threshold for automatic balance offset. When both the vendor and the associated customer balances reach this threshold, PortaBilling offsets the smaller of the two balances and decreases both balances by that amount. PortaBilling also creates xDR records for the vendor and the customer for this transaction.

   

4. Click Save in the toolbar.

This section of the handbook covers the setup of the environment owned by SmartCom. The configuration is performed by the GlobalNet admin.

If the GlobalNet admin has already created a new dedicated billing environment for this setup, make sure the SmartCom environment is fully prepared for configuration. To do this, the SmartCom admin must complete the initial PortaBilling configuration.

Since GlobalNet is configured as both a vendor and a customer, exclude the GlobalNet vendor from the routing list for calls sent from the GlobalNet customer to prevent a call termination loop.

1. For this, on the vendor’s panel, navigate to General configuration.
2. For the Offset balance with customer option, select GlobalNet incoming traffic customer from the list.
3. In the Minimum amount to offset field, specify the threshold for automatic balance offset. When both the vendor and the associated customer balances reach this threshold, PortaBilling offsets the smaller of the two balances and decreases both balances by that amount. PortaBilling also creates xDR records for the vendor and the customer for this transaction.
