XBert AI is Nextiva's AI-powered receptionist, a $99/month add-on that sits on top of your existing business phone system and handles incoming calls the way a trained front desk employee would. It greets callers, understands what they need, routes them to the right person or department, takes messages, and even answers common questions, all without a human in the loop.
This is not an IVR (those old "press 1 for sales, press 2 for support" systems everyone hates). XBert AI has an actual conversation with your callers using natural language. The difference in caller experience is significant.
We ran XBert AI through 30 days of real inbound call volume across a multi-location SMB to see how it actually performs when the stakes are real, not a demo environment.
For $99 a month, XBert AI handles what would otherwise require a dedicated front desk employee or an outsourced answering service that costs 3–5× more and delivers a worse experience. If your business takes inbound calls, and misses some, puts people on hold too long, or routes them wrong, this pays for itself in the first month.
The core job is handling the moment a call comes in. But what happens in that moment determines whether a customer stays or bounces to a competitor. XBert AI manages the full call lifecycle from first ring to resolution:
Four industries, four real demos. This is exactly what your callers hear when XBert answers, natural conversation, no phone trees, no hold music.
Reservations, hours, wait times, and dietary questions, handled without a host picking up.
Emergency service dispatch, tune-up booking, and seasonal demand spikes, no dispatcher needed.
Appointment scheduling, insurance questions, and urgent triage, sensitive calls handled correctly.
New client intake, attorney routing, and conflict checks, without a paralegal on the phone.
In our 30-day test, XBert AI handled inbound calls across a business averaging 80-120 calls per week. The results were measurable and immediate.
Missed call rate dropped to zero. Before XBert AI, roughly 18% of calls were going to voicemail during peak hours and after hours. Every single one of those is a potential customer who may not call back. That stopped on day one.
Average hold time was eliminated entirely. Callers were greeted and routed in under 10 seconds on 94% of calls. The remaining 6% involved complex routing scenarios that required brief queuing, still faster than a human front desk average.
Routing accuracy was 91% over the 30-day period. When XBert AI did misroute, it was most often on unusual requests outside the configured FAQ and routing rules, a training gap, not a product failure. Refining the configuration in week two brought accuracy to 96%.

The pricing argument for XBert AI isn't subtle. You're trading a five-figure annual cost, a human receptionist, or a patchwork of answering services, for a flat $99 a month. But the more interesting number isn't the savings. It's the revenue you're currently leaving on the table every time a call goes unanswered.

Annual Savings vs. ReceptionistA full-time front desk employee runs $3,200–$3,800/month with taxes and benefits. XBert AI is $99.
You're on a job and can't pick up, the phone rings out, goes to voicemail, caller hangs up.
Caller gets a live response in under a second. You finish the job. No one knows you were unavailable.
Voicemail doesn't convert. Callers who don't leave a message just dial your competitor next.
Every call gets answered first. First to respond wins the booking, that's just how service calls work.
A front desk employee costs $3,000+/month, calls in sick, and still misses calls during lunch.
$99 flat, 24/7, zero sick days, handles unlimited simultaneous calls. The math is embarrassingly one-sided.
After-hours calls go completely cold. Weekend inquiries sit until Monday, when the lead is already gone.
Calls at 11pm on a Saturday get the same experience as 10am Tuesday. Appointments booked while you sleep.
That scenario assumes only two new customers per month, calls that would have gone to voicemail. Most businesses capturing 80–120 calls a week will see significantly better returns than that, especially once after-hours coverage kicks in.
Nextiva holds solid ratings across the major review platforms. Here's how XBert AI stacks up in the wild, based on published user reviews.
Switching to Nextiva completely changed how we handle call volume. Our team isn't scrambling anymore, the AI picks up the overflow smoothly and our booking rate has noticeably improved.
I was skeptical about AI handling our phones, but the voice quality is really good and the platform is way easier to manage than I expected. Our tenants actually seem to prefer it over waiting for a callback.
For a law firm, missing a call can mean losing a five-figure case. XBert captures intake details 24/7 and routes urgent calls immediately. The calendar and CRM sync alone made this worth it.
We were dropping a double-digit number of calls every single day. That's just gone now. The AI answers instantly and our weekly lead volume is up 40%, it's not even close to what we were doing before.
Honestly, it paid for itself within the first few days. One client call that would have gone to voicemail on a Saturday morning turned into a job that covered the entire month's cost. Easy math.
Took under 10 minutes to get it running. By the time I finished my second cup of coffee, real calls were being handled by the AI. Revenue is up significantly since we stopped losing calls to voicemail.
No IT department required. The setup process is three steps. Nextiva walks you through it live on a call, and most businesses are fielding real calls before the hour is up.
XBert learns from your website, services, hours, and FAQs automatically. You answer a few questions on the setup call, that's it.
Pick your AI voice, set your business hours, define call routing rules, and customize the greeting. Change any of it later, anytime.
XBert starts handling calls, texts, and chats immediately. View real-time transcripts, bookings, and revenue right from your dashboard.
The product UI is cleaner than most business phone dashboards. Here's what you’re actually getting access to.
XBert picks up every call with a natural, human-like voice. No hold music, no phone trees, no missed opportunities, even at 2am on a Sunday.
Real-time calendar integration means XBert sees your availability and books, confirms, reschedules, and sends reminders, without you touching the phone.
Every call, every booking, every dollar captured. Full transcripts, call summaries, and weekly performance reports so nothing slips through.
Phone, SMS, web chat, all in one place. Every customer conversation is tracked and accessible so nothing falls through the cracks.

The stuff people ask before they commit. Straight answers, no fluff.
A full-time receptionist runs $35,000–$45,000 per year with benefits, works a 40-hour week, takes vacations, and calls in sick. XBert AI is $99/month , $1,188 per year, and works 24/7 with no downtime. Most businesses offset the entire annual cost in the first week by capturing calls they'd otherwise miss.
XBert introduces itself as a virtual assistant from the start, no deception involved. The voice sounds natural and conversational, not robotic. And here's the number that surprised us: in Nextiva's own customer surveys, 94% of callers said they preferred getting an instant AI response over being put on hold waiting for a human. Speed wins.
You define the rules. XBert can instantly transfer specific call types, urgent situations, high-value inquiries, VIP clients, directly to you or your team based on whatever criteria you set. In practice, roughly 80% of calls are handled entirely by the AI without needing a transfer. The 20% that do get transferred are the ones that actually need your attention.
Yes. You either forward your existing number or get a new one, tell Nextiva your business hours, services, and routing preferences, and they configure the AI live with you on the call. Most businesses are up and running in 4–6 minutes. No technical skills required, if you can answer a few questions out loud, you can set this up.
Nextiva offers a 30-day money-back guarantee, email them, get a full refund, no questions asked. They'll even help you move your number back or to another service. Context that matters: fewer than 3% of customers request a refund. That's not a marketing number. That's just the product working as advertised.
XBert is already handling complex, high-stakes calls across legal intake, HVAC emergency dispatch, HIPAA-compliant medical scheduling, and financial services. The setup call trains the AI on your specific scenarios, not a generic template. If Nextiva genuinely can't handle your edge cases, they'll tell you that up front. That transparency is worth something.
XBert AI earns its 9.2 BH Score because it solves a real, expensive problem for SMBs, missed calls and inconsistent caller experiences, at a price point that requires almost no justification. The setup is fast, the results show up in the first week, and the ongoing cost is trivial compared to the alternative. The only meaningful friction is the Nextiva dependency. If you're already on Nextiva or evaluating a business phone system, adding XBert AI is a straightforward decision.
