# ElevenAgents: Parallel tool calls: Agent prompt configuration now includes enable\_parallel\_tool\_calls…

By Steven Van · 2026-09-21

ElevenAgents can now call multiple tools per turn, and gets a new model, Slack alerting and phone number search filters.

ElevenAgents prompt configuration now includes **enable\_parallel\_tool\_calls**, a boolean that defaults to true. When it's on, supported models can run multiple tools in a single turn instead of one at a time.

The same [update](<https://elevenlabs.io/docs/changelog/2026/9/21#elevenagents>) to [ElevenLabs](<https://creatorstoolbox.com/tools/elevenlabs>) agents covers a few other changes:

- gpt-6-astra was added to the agent LLM options.

- Agent alerting now supports Slack channels, alongside PagerDuty and webhook notifiers.

- A new cursor-paginated phone number endpoint adds filters for provider, outbound support, assigned agent and branch, label and phone number.
