CallSprout + ElevenLabs
Put an agent built on ElevenLabs Agents on your CallSprout phone lines, with the ElevenLabs voice you picked, and hand calls to your team whenever a person is needed. Available for ElevenLabs.
The ElevenLabs integration features described on this page require an active, permitted connection to ElevenLabs. Availability depends on that system's supported APIs and permissions.
How CallSprout works with ElevenLabs.
Most people know ElevenLabs for its voices. ElevenLabs Agents goes further: it is a complete platform for building voice agents, with the voice, the language model, a knowledge base and tool calls configured in one place. Teams that already sound the way they want on ElevenLabs often want that same agent answering their business line.
CallSprout connects your ElevenLabs agent to your CallSprout phone system over SIP. The agent answers inbound calls on the numbers you choose and can place outbound calls through CallSprout. ElevenLabs runs the conversation and the voice. CallSprout stays the phone system underneath: your numbers, your routing, and the people who pick up when the agent hands off.
Bring-your-own-agent connections are in early access, and we set each one up with you. If you would rather not run your own agent, Sage, CallSprout's AI voice agent, is built into the platform. The connect your tools page covers both.
CallSprout and ElevenLabs, working together.
What Sage does once your call data flows into the tools you already use.
Callers hear the ElevenLabs voice you configured for your agent, on the CallSprout numbers they already call.
Your agent's prompt, model, knowledge base and tools stay in ElevenLabs Agents. CallSprout carries the call without changing how the agent behaves.
Route inbound calls to the agent and let it place outbound calls through CallSprout, so both directions run on one phone system.
When a caller needs a person, the agent transfers the call to an extension, ring group or queue on CallSprout, and your team answers on the phones and apps they already use.
ElevenLabs runs the agent, CallSprout runs the phones
Everything about how the agent sounds and what it says lives in your ElevenLabs account: the voice, the prompt, the model, the knowledge it draws on and the tools it can call. Your ElevenLabs agent can use those tools to look up an account or create a ticket in your help desk while the caller is still talking. CallSprout does not change any of that.
What CallSprout adds is the phone system around the agent. Numbers, business hours, ring groups, queues and call flows are set in CallSprout. You decide which calls reach the agent, and when a call needs a person, it comes back to a CallSprout extension or group.
If your agent's tools already include an MCP server, the agent keeps using it. If a tool you need has none, we can build one.
What early access means
We set up each bring-your-own-agent connection by hand. On a short call we look at your ElevenLabs agent, the numbers it should answer, and where transfers should go. Then we configure the SIP connection on both sides and test inbound calls, outbound calls and hand-offs before anything goes live.
Your ElevenLabs account, its usage and its billing stay yours, under ElevenLabs' own terms. CallSprout provides the phone system, the numbers and your team on the other side of a transfer.
What this looks like day to day.
Your agent answers the main number in the voice your brand uses everywhere else. Sales questions go to the sales ring group on CallSprout when the caller is ready to talk to someone.
CallSprout's call flow sends calls to the agent when every person in the queue is on another call. The agent handles routine questions and transfers anything urgent back to the first person free.
The agent places outbound calls through CallSprout from your business number. If the customer asks for a person, the call goes to your team instead of ending.

ElevenLabs, answered.
- Does CallSprout work with ElevenLabs Agents?
- Yes. CallSprout connects to ElevenLabs Agents over SIP, so an agent you built there can answer inbound calls on your CallSprout numbers and place outbound calls through CallSprout. The connection is in early access, and we set it up with you.
- Is this only for ElevenLabs voices?
- No. ElevenLabs Agents is a full agent platform, and the connection carries the whole agent: its voice, prompt, model and tools. The voice is one part of what you configure in ElevenLabs.
- Can the agent transfer callers to my team?
- Yes. The agent can hand a call to an extension, ring group or queue on CallSprout, and the person answers on their CallSprout phone or app. We test transfers with you during setup.
- Do I need my own ElevenLabs account?
- Yes. The agent and its usage live in your ElevenLabs account, under ElevenLabs' terms and billing. CallSprout provides the phone system the agent runs on.
- Should I use ElevenLabs or Sage?
- If your team already has an ElevenLabs agent it likes, connect it. If you do not have an agent yet, Sage is built into CallSprout and needs no separate platform.
