Repo:
Let Hermes do it: tell it to follow skills/setup/SKILL.md from the repo.
By hand:
1. `hermes plugins install ashwanthbalakrishnan5/hermes-whatsapp-voice --enable`
2. `hermes config set plugins.entries.hermes-whatsapp-voice.settings.owner_number +15551234567`
3. `hermes whatsapp-voice pair` (or the WhatsApp Voice tab in the dashboard)
4. In ~/.hermes/.env set API_SERVER_ENABLED=true and API_SERVER_KEY, then restart the gateway
5. `hermes whatsapp-voice serve`
Keep it on 24/7: `hermes whatsapp-voice service` prints a ready-made background service file.
Test it: `hermes whatsapp-voice call "Testing the new voice line"`
Needs Hermes 0.21.5 or newer.
