Key Takeaways: Your Five9 agents handle calls during business hours. NextPhone handles everything after that. Forward your Five9 calls to a dedicated AI number — after-hours, weekends, overflow. No API, no migration, no number change. $199/mo flat.
Your Five9 Agents Go Home at 6 PM. Your Customers Don't.
Your contact center runs Five9. During business hours, your agents answer calls, log interactions, route to the right department. The system works.
Then 6 PM hits. Your agents clock out. A customer calls at 7 PM — AC died in 95-degree heat. Voicemail. They call the next company. A lead calls at 9 PM after seeing your Google Ad. Voicemail. They book with a competitor. Saturday morning, a pipe bursts. Voicemail. You find out Monday.
In our analysis of 130,175 customer service calls from 45 home services contractors over 7 months, 74.1% of calls went completely unanswered. The biggest gap isn't during business hours — it's after-hours, weekends, and overflow periods when your agents are unavailable.
73% of calls to home services businesses come outside standard 9-to-5 hours. And 15.9% contain urgency language — "emergency," "flooding," "no power." Those emergency calls average $4,200 in revenue. Every one that hits voicemail goes to whoever answers first.
Five9 is built for staffed contact centers. The problem is the hours when nobody's staffing it.

Get Started FreeHow It Works: 3 Steps
NextPhone gives you a dedicated AI phone number. You forward your Five9 calls to it when your agents aren't available. That's the entire integration.
Step 1: Sign Up and Get Your AI Number
Create your NextPhone account and get a dedicated phone number. Train the AI on your business — services, pricing, service areas, hours, common caller questions. Takes about 15 minutes.
Step 2: Forward Your Five9 Calls
Configure Five9 to forward calls to your NextPhone number during specific conditions:
- After-hours: Calls route to AI when your contact center closes (6 PM to 8 AM)
- Weekends and holidays: Full AI coverage without paying overtime or hiring night staff
- Overflow: When all agents are busy, calls forward to AI instead of sitting in queue
- Always-on: Every inbound call goes to AI first (useful for small businesses that don't staff a contact center)
Most Five9 users start with after-hours forwarding — agents handle daytime calls, AI picks up everything else.
Step 3: Go Live
Test with a few calls. Verify the AI answers correctly, collects the right information, and routes emergencies to your on-call number. Adjust and go live. Under 30 minutes total — not the 4-12 weeks a Five9 implementation takes.
Your customers call the same number. Nothing changes on their end.
What NextPhone Handles
When calls forward to NextPhone, the AI takes over:
Answers every call in under 5 seconds. No queue, no hold music, no "your call is important to us." The AI picks up and starts a natural conversation.
Qualifies leads. Collects the caller's name, phone number, what service they need, their address, urgency level, and preferred appointment time. You get structured data, not a voicemail you have to transcribe.
Books appointments. Sends callers an SMS with your booking link. Appointments show up on your calendar automatically.
Detects emergencies. When callers say "pipe burst," "no AC," "flooding," or "ASAP," the AI flags the call as urgent and can transfer directly to your on-call number. Emergency calls reach someone — not a voicemail box.
Sends summaries. After every call, you get an email and SMS with caller information, what they need, urgency level, and a full transcript.
Syncs to your CRM. HTTP webhooks push call data to Salesforce, ServiceNow, HubSpot, or any system with an API. The same CRM your Five9 agents use gets the after-hours data too — no gap in your customer records.
Works every hour your agents don't. Midnight, 3 AM, Thanksgiving, Christmas morning. The AI never takes PTO.
Pricing: Five9 + NextPhone

| Setup time | 4-12 weeks | Under 30 minutes | — |
If you already run Five9 for your daytime contact center: NextPhone adds after-hours and overflow coverage for $199/mo. Compare that to hiring night-shift agents at $35,000+/year each (plus benefits, training, scheduling). That's a 93% cost reduction for 24/7 coverage.
If you're a small business researching Five9: The 50-user minimum means $5,950/mo before your first call. A 5-person team pays for 45 unused seats — $5,355/month wasted. NextPhone delivers AI call answering at $199/mo with no user minimums. For most small businesses, that's the right starting point.
One extra captured job per month at $3,500 pays for NextPhone 17 times over.

Get Started FreeFrequently Asked Questions
Do I need to change my Five9 setup?
No. Call forwarding is a standard Five9 feature. You configure a rule to forward calls to your NextPhone number under specific conditions (after-hours, overflow, weekends). Your Five9 contract, pricing, and agent setup stay the same.
Can my Five9 agents still handle calls during business hours?
Yes. The typical setup is: Five9 agents handle calls 8 AM to 6 PM, NextPhone handles everything outside those hours. During business hours, calls route through Five9 as normal. You can also configure overflow — if all agents are busy, calls forward to AI instead of waiting in queue.
Does NextPhone work with the same CRM as Five9?
Yes. NextPhone pushes data via HTTP webhooks to Salesforce, ServiceNow, HubSpot, and any other CRM with an API. Your after-hours call data lands in the same CRM your Five9 agents use during the day. No gap in customer records.
What if a caller needs to speak with a person after hours?
The AI can transfer calls to any phone number you configure — your on-call staff, a mobile number, or a specific team member. For emergencies, the AI detects urgency language and routes immediately. For non-urgent calls, the AI handles the conversation and sends you a summary for next-day follow-up.
Is this a replacement for Five9?
No. Five9 is a full contact center platform — workforce management, analytics, compliance, multi-channel routing. NextPhone is an AI receptionist that answers calls when your agents aren't available. They serve different purposes and work together. Five9 for your staffed hours, NextPhone for everything else.
