Looking for the best phone answering service?
Missed calls driving you crazy? You're not alone. We all get frustrated by ringing phones and voicemails piling up. There just aren't enough hours in the day to return every call.
But what if you had an AI virtual assistant answering phone calls for you?
Conversational IVR systems with AI technologies like NLU, NLG, and TTS can help automate customer service interactions, freeing up agents for more valuable interactions and enabling complex, two-way conversations with customers, even during tricky collections calls, as seen with ING Bank.
After implementing this technology, ING Bank saw a 50% decrease in agent workloads and a nearly 60% increase in customer payment promises. [1]
