talku.ai offers AI voice agents that work with the phone setup a business already has. You forward calls from your SIP trunk or PBX to the agents through a SIP address, and they take care of routine conversations such as answering common questions, booking appointments and routing callers.
Pricing is a flat per-minute rate with no separate telephony charges, according to the site. You can talk to a live demo agent or book a demo. It suits companies that want calls handled outside office hours without replacing their phone system.
