AI Customer Service Phone
24/7 Support That Sounds Human
Phone Stack's AI customer service phone software handles tier-1 support 24/7 — order status, FAQs, returns, account questions — and seamlessly escalates anything complex to a human. Sub-second voice latency, $0.25/min.
What is AI customer service phone software?
AI customer service phone software uses a voice agent — not a human — to answer inbound support calls and handle tier-1 cases. Phone Stack covers the full lifecycle: call answer → intent detection → data lookup → resolution → escalation if needed → CRM logging.
Think of it as the voice channel for products like Intercom Fin, Decagon, or Sierra — except focused on the phone, where 30–60% of support volume still lives.
