Handling your business calls manually can be time-consuming and prone to missed opportunities. This is where an AI voice agent comes in.
An AI voice agent is a smart software system that interacts with customers over voice calls. It can understand questions, provide relevant answers, execute actions like updating records or scheduling meetings, and escalate to human agents when needed. Unlike traditional phone systems, AI voice agents work around the clock, handle multiple calls at once, and provide consistent, high-quality interactions.
By combining AI voice agents with AI SDRs (Sales Development Representatives), businesses can automate lead qualification, manage top-of-funnel operations, and ensure no potential customer slips through the cracks, all without adding extra staff.
