How can we integrate voice call alerts into process automation workflows in Celonis?

Hi everyone,

I’m exploring ways to improve real-time communication in process workflows, especially for critical events like payment failures, delivery delays, or approval escalations.

Currently, most setups rely on email or SMS notifications, but in some cases, those don’t get immediate attention. I’m considering using programmable voice calls as an alternative for high-priority alerts.

For example:

  • Triggering an automated call when an SLA is breached
  • Voice alerts for urgent approvals
  • Escalation calls when a process is stuck

Has anyone here tried integrating voice-based notifications with Celonis (via APIs or external systems)?

Also curious about:

  • Best way to trigger voice calls from Celonis (Action Flows / APIs?)
  • Handling retries or fallback logic
  • Any real-world use cases where voice alerts improved process efficiency

I came across some programmable voice API solutions like https://africala.net/za/products/voice-api/that support automated calls, and I’m trying to understand how this can fit into a process mining or execution setup.

      Hey ​@africala 

      you can definitely build this using action flows. celonis doesnt have a native voice node so the easiest way is using the HTTP Make a request module. you just pass your api endpoint and json payload there to trigger the voice api call.
       

      for the retry and fallback stuff action flows has built in error handling. you just right click the http module and add an error handler. you can use the break directive to retry the api call a few times or use an ignore route to trigger a fallback like sending a slack message if the call fails.
       

      i havent used that specific api link u shared but we do exactly this for custom sms gateways and it works perfect for high priority sla alerts. just run the action flow on a schedule or record trigger when the case hits your threshold.
       

      hope this points u in the right direction let me know if u get stuck on the http setup or maybe there is some changes ?
