Telephony
SIP providers that supply the client's phone number for voice agents
Pick one supported telephony provider for the client's SIP number, then bind it in Happ.
Connect a provider
- Create an account with the provider and get SIP credentials (login, password, server URL) for the phone number.
- Add the phone in Happ: Phones > Add Phone (see Phone & SIP Setup).
- Add the integration: Integrations > Add Integration > pick the provider, enter credentials, activate.

ElevenLabs (premium voices)
Not a telephony provider — supplies high-quality text-to-speech. Integrations > Add Integration > ElevenLabs, enter your API key from elevenlabs.io. ElevenLabs voices (multiple languages, accents, voice cloning) then appear in the assistant's voice settings. Without it, the agent uses one of the 30 built-in voices.
