ElevenLabs

Elevenlabs is an AI platform for voice and audio. It enables highly realistic text-to-speech generation, voice cloning, audio transcription, multilingual dubbing, and the creation of conversational voice agents.

You can use it for, among other things:

  • Text-to-Speech (TTS): converting written text into natural-sounding speech
  • AI voice assistants: building chatbots and real-time conversational agents

NethVoice – ElevenLabs Integration​

The integration between NethVoice and ElevenLabs allows the use of AI voice services directly within phone calls, with the following configuration steps:

1. Configure the ElevenLabs trunk in NethVoice​

  • In the NethVoice administration interface, go to Lines → VoIP.
  • Add a new trunk from the supported providers list and select ElevenLabs.
  • Use a dummy phone number and credentials (username/password).
  • These credentials will later be used in the ElevenLabs configuration.

2. Create a SIP extension in advanced NethVoice settings​

  • Access the advanced NethVoice interface.
  • Create a PJSIP extension that will be used to forward calls to ElevenLabs.

In the extension advanced settings, replace the Dial field with:

PJSIP/NOME_TRUNK/sip:NUMERO_TEL@sip.rtc.elevenlabs.io

Where:

  • NOME_TRUNK = the name assigned to the ElevenLabs trunk in NethVoice
  • NUMERO_TEL = the dummy phone number used during trunk configuration

Example:

PJSIP/ElevenLabs/sip:+39333333333@sip.rtc.elevenlabs.io

3. Configure ElevenLabs SIP Phone Number​

In ElevenLabs, create a new SIP Trunk phone number using the same dummy numbering defined in NethVoice.
