In order to use the “Start Flow After Receiving a Call” or “Start Flow After a Missed Call” triggers, your account must be connected to a voice-enabled channel, such as a voice-enabled virtual number purchased from Twilio. For more information on “Phone Call” flows and Interactive Voice Response (IVR), check out Introduction to IVR.


Start a Flow After Receiving a Call

Once you have created a “Phone Call” flow, you can create this trigger via the following steps:

  1. Navigate to the "triggers" tab, and then click the "Create Trigger" box.

  2. Click the "Start a Flow After Receiving a Call" option.

  3. Select the flow you would like to trigger (only IVR flows will appear in the dropdown menu).

  4. Optional: You can choose the group(s) to which your keyword trigger will apply. If you leave this field empty, your keyword trigger will apply to anyone who calls.

  5. Click "Create Trigger.”



Start a Flow After a Missed Call

This trigger only works on accounts that are connected to a voice-enabled channel; however, you can use this trigger to start a standard text messaging flow or an IVR phone call flow. Create this trigger via the following steps:

  1. Navigate to the "triggers" tab, then click the "Create Trigger" box.

  2. Click the "Start a Flow After a Missed Call" option.

  3. Select the messaging or phone call flow that you would like to trigger.

  4. Click "Create Trigger.”
