Getting RufLab live takes less than an hour from signup to first real call. This guide walks you through every step: creating your account, configuring how your assistant behaves, connecting your phone number, and going live. You do not need any technical knowledge or special hardware — everything runs in your browser.
RufLab offers a 14-day free trial with no credit card required. You get full access to all features during the trial so you can test the assistant with real calls before committing to a plan.

Walk through a realistic scenario — ask a question your customers typically ask, try booking an appointment, or test what happens when you trigger a forwarding rule.Review the call transcript in your dashboard to confirm the assistant responded correctly. Adjust the call logic or voice settings if anything needs tweaking.
