We have noticed that our Ai agent turn silent right after sending the sms message to the caller. It is supposed to get back to the caller and ask "Have you received it?" Instructions has been included on the system prompt ( agent should get back to the caller after sms sent.) can you please check on your system. This happens to 2 organizations: Organization 1 Call Id: 019b01f7-ae55-7114-94b0-dfb75a79056b Call Id: 019b01e8-73b7-799e-9ffe-550894bdd736 Organization 2 Call Id: 019ae21a-766c-7000-8224-1b2cdc7219b8 Call Id: 019ae1c2-e3c8-7dda-affe-56e3ee3c309c Please advise us on how to fix it.

Actionable Fix: Update your workflow to explicitly add a follow-up message right after the SMS tool call, since idle messages are disabled during tool execution. For example, in your workflow configuration:

json
{
  "steps": [
    { "type": "tool", "name": "send_sms" },
    { "type": "say", "exact": "Have you received it?" }
  ]
}

This ensures the agent always prompts the user after sending the SMS. Check your workflow or node setup to confirm this follow-up step is present and not just in the system prompt.

I am not using a workflow. I am using the regular system prompting
