About

Xbert

Xbert is Nextiva's AI voice agent that answers business phone calls 24/7, greets callers, captures details, books appointments, sends follow-up messages, and escalates urgent conversations to human staff. Part of Nextiva's unified customer experience platform, Xbert works across voice, SMS, and web chat channels using conversational AI.

Xbert is delivered as part of the broader Nextiva platform rather than a standalone product, which means it inherits Nextiva's business phone, texting, and contact center rails on day one — new users get a business number, call flows, and integration to Nextiva's CRM without having to stitch third-party pieces together. That packaging is the main reason Xbert appears in Nextiva's own comparison round-ups as a "digital concierge" for small and mid-sized businesses rather than a purely developer-facing voice agent. The product handles inbound greetings, question answering from a business's knowledge base, appointment booking, message capture, and warm hand-off to a human agent when confidence drops or the caller asks for a person. Callers who reach Xbert after hours or during overflow are treated as first-class conversations rather than voicemail, and the transcripts flow into the same activity feed a human agent would see the next morning. Xbert is priced inside Nextiva's tiered plans rather than as a per-minute add-on, so total cost is predictable for businesses that already run their phone system on Nextiva. That pricing pattern is the differentiator most reviewers call out against per-call or per-minute AI receptionist alternatives.
