Check calling availability with Sendwo
Is WhatsApp Calling available to every Sendwo account?
  • This is a Beta feature.

  • Ask our team to check your number before planning a rollout.
Where do I find the calling settings?
  • Open Chatbot Manager and select your WhatsApp bot.
  • Go to Automation → WhatsApp Calling (Beta).
  • Use Settings to configure the experience and Agent Desk to handle calls.
Does enabling Callback permission let me call anyone?
  • No. Customers must grant the required calling permission.
  • Enabling the option allows that permission flow; it does not replace customer permission.
  • Business-initiated calling must also be available for the account.

  • After the call ends and the recording has been processed.
