Meta Muse + AgentLine

Voice for Meta's Muse agents

Muse already plans, writes, and validates across a repo. AgentLine adds a real phone number so a Muse agent can call, answer, and read SMS.

Why give Meta Muse a phone number

Works next to Muse subagents

Muse already fans out background agents. AgentLine is one more tool those agents can call: numbers, transcripts, live turns.

No audio pipeline in Muse

Muse Spark never sees PCM. It sees transcripts and writes the next spoken sentence.

A number the agent owns

Each Muse session can attach its own E.164 identity instead of borrowing a shared call-center trunk.

Set up Meta Muse

How the skill and the service land on this runtime.

1. Set your API key

The relay reads AGENTLINE_API_KEY from the environment. Export it where Muse Code runs.

bash

export AGENTLINE_API_KEY="al_live_..."

2. Install the relay service

Muse has no built-in harness, so --handler must be a shell command that reads a caller prompt on stdin and prints the reply — without it the relay installs but cannot answer calls.

bash

python -c "import urllib.request; urllib.request.urlretrieve('https://api.agentline.cloud/static/agentline_relay.py','agentline_relay.py')"
python agentline_relay.py install --agent-id agt_xxx --runtime custom --handler "YOUR_HANDLER_COMMAND"

FAQ

Can Muse make phone calls?

Yes — Muse calling runs through AgentLine. Install https://agentline.cloud/skill.md, set AGENTLINE_API_KEY, create an agent, and buy a US or Canada number; then Muse places outbound calls with POST /v1/calls, and answers inbound calls and inbound SMS on that same number.

Does AgentLine work with Muse Code?

Yes. Install https://agentline.cloud/skill.md, set AGENTLINE_API_KEY, create an agent, and buy a number.

Does this cover Muse Spark too?

Yes. Muse is the agent; Muse Spark is the model. The AgentLine skill sits on the harness and works with either.

Do I need Twilio or SIP?

No. AgentLine handles provisioning, transcription, and voice. Muse only reads and writes text.
