How to Build a Conference Application the No-Code Way Using PHLO

How to Build a Conference Application the No-Code Way Using PHLO

You can create and deploy a workflow to implement conference calling with a few clicks on the PHLO canvas.

Prerequisites

To get started, you need a Plivo account — sign up with your work email address if you don’t have one already. To receive incoming calls, you must have a voice-enabled Plivo phone number. You can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API.

Create the PHLO

To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.

  • Click CREATE NEW PHLO.
  • In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming call, or API request.
  • From the list of components on the left side, drag and drop the Conference Bridge component onto the canvas. When a component is placed on the canvas it becomes a node.
  • Draw a line to connect the Start node‘s Incoming Call trigger state to the Conference Bridge node.
  • In the Configuration tab at the right of the canvas, enter a Conference ID for your conference. You can also add an announcement message to greet callers, and configure the hold music.
  • Once you’ve configured the node, click Validate to save the configuration.
  • Give the PHLO a name by clicking in the upper left, then click Save.

Your complete PHLO should look like this.

Assign the PHLO to a Plivo number

Once you’ve created and configured your PHLO, assign it to a Plivo number.

  • On the Numbers page of the console, under Your Numbers, click the phone number you want to use for the PHLO.
  • In the Number Configuration box, select PHLO from the Application Type drop-down.
  • From the PHLO Name drop-down, select the PHLO you want to use with the phone number, then click Update Number.
