@Valentin Ffrench Hmm, now that I started researching, the ElevenLabs does not offer a direct outbound calling functionality. It seems Twilio or similar 3rd party services should be integrated to place the outbound calls using the audio generated by ElevenLabs. Which means additional cost per call, which varies across different regions (https://www.twilio.com/en-us/voice/pricing/us - as example, some Asian countries are up to x20 more expensive than USA). In such case, it would be difficult to estimate the operational expenses for 3rd party/Twilio API usage per month, which are incurred on top of ElevenLabs charges. Overall, this is not ideal, which forces to reconsider the first approach - capturing customer details during a call, and having customer initiate the call via ElevenLabs widget integrated into the website
