Can my AI agent trigger an incident alert SMS to the on-call engineer?

Absolutely. You can provide your Twilio phone number, the destination E.164 number, and the alert body text. The agent will hit the Twilio API instantly, dispatch the SMS, and return the Message SID along with delivery status.

How can I stop a rogue voice call stuck in a loop?

Ask your agent to list active or recent voice calls and find the offending Call SID. Then instruct the AI to cancel the active call by its ID. The agent updates its status to 'canceled', dropping the connection right away.

Can it check how much my company has spent so far this month?

Yes. Ask the agent to pull your account's usage records. It interfaces with the Twilio billing records and can display breakdowns of amounts sent, call durations, and costs incurred, giving you full transparency without opening the dashboard.
