How to…

Let’s say you only want to allow your customers from the UK and Ireland to initiate callbacks. This can be done by setting up separate charging for different call legs and restricting the destinations in the call legA tariff to destinations in the UK and Ireland.

1. Edit the Accounting section of the Callback calling application:
   • Open the Callback calling application and select Accounting;
   • Specify the CLD prefixes for legA and legB in the LegA CLD prefix and LegB CLD prefix fields;
   • Click Save.

     

     Callback trigger instances are modified in the same manner as the Callback IVR application.
2. Create tariffs that will be used for separately charging for different call legs following the instructions described in the previous chapters.

   

3. Enter rates to the tariffs:
   • Enter rates for destinations to the UK and Ireland that will be used for charging for call legA to the tariff;

     

   • Enter rates to the tariff that will be used for charging call legB and all other required destinations, except the UK and Ireland.
4. Modify the callback product:
   • On the Usage charges panel add a new rating entry with your PortaSIP node, the tariff that will be used for charging for call legA and the access code in this format: <LegA CLD Prefix> + <Access number> (e.g., 123#18882325698);

     

   • Add another rating entry with your PortaSIP node, the tariff that will be used for charging call legB and the access code in the format <LegB CLD Prefix> + <Access number> (e.g., 456#18882325698).

     

1. Perform steps 1-3 as described in the section above.

   

   

   

2. Modify the callback product:
   • On the Usage charges panel add a new rating entry with your PortaSIP node, the tariff that will be used for charging for call legA and the access code in the format <LegA CLD Prefix> + <Access Code> (e.g., 123#WEBCALLBACK);

     

   • On the Usage charges panel add a new rating entry with your PortaSIP node, the tariff that will be used for charging call leg A and the access code in this format: <LegB CLD Prefix> + <Access Code> (e.g., 456#WEBCALLBACK).

     

This option allows you to apply a single tariff to charge users for calls made to their numbers (call leg A) from multiple access numbers (e.g., if you provide DNIS callback), and to apply another tariff to charge users for calls to destination numbers (call leg B).

To match all access numbers to corresponding tariffs in the product, do the following:

1. Configure the callback services as described in the Setting up callback services handbook.
2. Configure the LegA CLD Prefix and LegB CLD Prefix of the Callback calling IVR applications and then perform further tariff and product configurations. To do this, follow the instructions described in the …Configure separate charge for incoming leg chapter in the How to… handbook of the Prepaid services section.

You may want to greet your end users or guide them through the IVR application once they have dialed the access number. Brand prompts is the audio tool that helps you reach this goal.

To configure custom brand prompts, perform all of the following steps:

1. Record a voice prompt, e.g., welcome message, in the .wav, .mp3, .mp4, or .m4a format. Give the prompt a proper name that corresponds to the prompt type, e.g., "welcome.mp3" for a welcome message.
2. Copy the prompt file to your PortaSwitch server, e.g., to the /porta_var/tmp folder.
3. Log in to a processing node via SSH.
4. Convert the prompt into the .au and .g729 formats using the PortaOne converter – prompt_converter.pl.

   For this, run the following command:

   /home/porta-um/scripts/prompt_converter.pl --timeout 14 --config /etc/porta-one/psmsc/periodic–tasks–<SIP_IP>.conf --debug <file_name>

   where file_name is the name of the file, and SIP_IP is the IP of the corresponding sip mu-bundle on your PortaSwitch server.

   Example

   The file name: welcome.mp3

   The SIP IP: 111.111.11.112

   The command:

   /home/porta-um/scripts/prompt_converter.pl --timeout 14 --config /etc/porta-one/psmsc/periodic-tasks-111.111.11.112.conf --debug welcome.mp3

   You can also convert all files on the server of the .mp3 format at once. Specify “*” as the file name, e.g., *.mp3 will convert all files in the .mp3 format.

5. After the conversion, you need to change the prompt names using the following command:

   rename 'new_' '' *.au *.g729

   Example

   The file names after the conversion: new_welcome.au and new_welcome.g729

   The command:

   rename 'new_' '' *.au *.g729

   The file names after applying the command: welcome.au and welcome.g729

6. Create new folders to place the brand prompts there. For this, run the following commands:

   mkdir /porta_var/psmsc/custom-files/prompts/brands/<your_custom_name> 
   mkdir /porta_var/psmsc/custom-files/prompts/brands/<your_custom_name><language>  
   

   where <your_custom_name> is the name of the folder for your custom prompts. The same folder name should be specified in the Brand prompts field of a voice application settings in step 9.

   Instead of the <language> for the second folder, use the two-letter code of the language the prompts are recorded in.

   Example

   If the folder name is canadian_calling_cards and the prompt language is English, then the command will be:

   mkdir /porta_var/psmsc/custom-files/prompts/brands/canadian_calling_cards
   
   mkdir /porta_var/psmsc/custom-files/prompts/brands/canadian_calling_cards/en

7. Place the brand prompts in the newly created <your_custom_name>/<language> folder by using the following commands:

   mv <required file name>.au /porta_var/psmsc/custom-files/prompts/brands/<your_custom_name>/<language>
   
   mv <required file name>.g729 /porta_var/psmsc/custom-files/prompts/brands/<your_custom_name>/<language>

   Example

   For the canadian_calling_cards folder and English as the prompts language, the command will be:

   mv welcome.au /porta_var/psmsc/custom-files/prompts/brands/canadian_calling_cards/en
   
   mv welcome.g729 /porta_var/psmsc/custom-files/prompts/brands/canadian_calling_cards/en

   If you want to move all the files of a specific format at once to a needed folder, then use *.au and *.g279 instead of the file names. So the commands will be:

   mv *.au /porta_var/psmsc/custom-files/prompts/brands/canadian_calling_cards/en
   
   mv *.g729 /porta_var/psmsc/custom-files/prompts/brands/canadian_calling_cards/en

8. Repeat steps 1-7 for each processing node of the installation.
9. Configure the brand prompts on the Voice applications page of the web interface.
   • Open Prompts & notifications and enable the Play welcome message toggle.
   • Go to Prompts customization and specify the folder name in the Brand prompts field created in step 6, e.g., canadian_calling_cards.
