How to Choose an IVR Provider: 12-Point Checklist 2026
Most IVR purchases go badly because buyers ask the wrong questions. Vendors sound great in demos — and deliver frustration in production. This checklist is built from 200+ real deployments, the questions that separate "works in demo" from "works for 3 years without migration pain".
Before You Start Comparing Vendors
Clarify these internally first:
- Expected call volume (inbound, outbound, peak CC)
- Geographic reach (which countries?)
- Integration requirements (CRM, EHR, billing, ticketing)
- Compliance needs (HIPAA, PCI-DSS, GDPR, TCPA, DLT)
- Budget ceiling (monthly and annual)
- Go-live deadline
Without these, every vendor sounds equally good.
The 12-Point Checklist
1. Can I see the full pricing breakdown, including hidden fees?
Ask specifically: setup fees, DID rental, SIP trunk charges, recording storage, TTS/ASR minutes, API call fees, premium support, failover/HA surcharge, integration fees. Get it in writing.
Red flag: "We'll send pricing after the demo" or "it depends on your usage". Translation: opaque pricing means future bill shock.
2. What's the real concurrent-call capacity, not the marketing number?
Every vendor advertises "unlimited" or "10,000+ CC". Reality: default accounts are capped at 10–50 CC until you request increases and prove volume. Ask for the specific cap on your account at go-live, and the process to scale up.
Red flag: vendor can't give you a specific starting number.
3. What's the SLA, and what happens if you miss it?
"99.9% uptime" = 43 minutes of downtime per month. "99.99%" = 4 minutes. Big difference. Ask: what's the SLA credit if breached? Who monitors? Historical uptime last 12 months?
Red flag: no written SLA, or SLA credits capped at 5% of monthly bill (useless).
4. How do I export my data if I leave?
Call recordings, CDRs, contacts, campaign configs — how do you get them out? In what formats? How long does it take? Are there exit fees?
Red flag: "you can't export in bulk" or "export requires professional services engagement". This is intentional lock-in.
5. What's the actual contract term and renewal structure?
Many vendors require 1–3 year commits with auto-renewal and 60–90 day cancellation windows. Push for month-to-month or pay a small premium for flexibility.
Red flag: 3-year lock-in with price escalators and auto-renewal.
6. Can I speak to three reference customers my size?
Specifically: customers in your industry, at your volume, who've been running for 12+ months. If vendor deflects to case studies, they don't have happy references.
Red flag: "we can't share customer info" — means they don't have references willing to vouch.
7. Who handles carrier-level issues?
When calls drop or audio has issues, is it your problem or theirs? Ask: do you own your SIP trunks or use aggregators? What's the escalation path for carrier problems?
Red flag: "we use third-party carriers, you'll need to work with them directly".
8. Is the API production-grade and documented?
Read their API docs before demo. Ask: rate limits, webhook reliability, retry policies, idempotency support. Build a test integration — watch how long that takes.
Red flag: docs have gaps, API lacks webhooks, or integration requires "professional services".
9. What compliance do you actually hold?
Ask for specific certifications with dates: SOC 2 Type II (not Type I), HIPAA BAA available, ISO 27001, PCI-DSS Level 1, GDPR DPA. Get audit reports in writing under NDA.
Red flag: "we're compliant" without certification documentation. Likely not.
10. What's my migration path if I need to move regions or scale?
You start with 100 CC in one country. What happens when you need 1,000 CC in five countries? Is that a new contract, a re-implementation, or elastic?
Red flag: "that's a different product tier" — means forced migration and price jumps.
11. Who's my account contact after go-live?
The sales engineer disappears after contract signing. Who's accountable after? Dedicated customer success manager or just a ticket queue?
Red flag: "our standard support channels" — code for "email us and wait 48 hours".
12. Can I do a 2-week production pilot with full platform access?
Real compatibility issues surface only in production. A 2-week pilot with real traffic, real integrations, real users catches 90% of deal-breakers before you sign.
Red flag: "we don't do pilots" or pilot requires signed MSA anyway.
Vendor Categories & When to Pick Each
Hyperscale cloud (Twilio, Amazon Connect, Google CCAI)
Pick when: global reach, elastic scale, dev team is comfortable with cloud APIs, budget is high. Avoid when: cost-sensitive, need managed service, have specific workflows.
Contact center suites (Genesys, Five9, NICE CXone)
Pick when: 50+ agent contact center, need omnichannel (voice + chat + email), willing to pay $100+/agent/month. Avoid when: pure IVR use case without agents.
Regional carriers / telcos (Knowlarity, Exotel, MyOperator in India)
Pick when: single-country focus, local compliance is mandatory, want Indian / regional support hours. Avoid when: global reach needed.
Specialized platforms (Zingle, Plivo, Telnyx)
Pick when: you want more than hyperscale generic but less than full contact center suite. Most flexibility per dollar. Best for outbound-heavy use cases, political, healthcare reminders, surveys.
Self-hosted (Asterisk, FreePBX, FreeSWITCH)
Pick when: very high volume, strict data residency, in-house VoIP expertise. Avoid when: small team without VoIP engineers. See our Asterisk vs Cloud comparison.
Red Flags to Walk Away From
- Pricing changes after you ask detailed questions
- "Unique technology" claims without technical docs
- Pressure to sign before end of quarter
- Claims of "proprietary AI" without measurable outcomes
- No written SLA or SLA that caps credits at minimal %
- Cannot provide SOC 2 / compliance reports
- No API or API requires separate "integration package" purchase
- References all from one industry or market
- Reviews on G2 / Capterra below 4.3 average with volume
The Decision Matrix
After gathering answers from 3–5 shortlisted vendors:
- Score each on a 1–5 scale against the 12 questions above
- Weight by importance to your use case (compliance might be 3x weight, cost might be 2x)
- Add qualitative factors: gut feel on account team, ease of working together during eval
- Do 2-week pilot with top 2 (if possible)
- Pick the one that made pilot easiest, not the one with the best demo
What to Negotiate
Once shortlisted, you have more leverage than you think:
- Setup fee waived (almost always possible)
- Month-to-month first 90 days, then annual commit
- Rate lock for 24 months
- Free DID ports in/out
- Extra concurrent calls during pilot
- Priority support included, not upsell
- SLA credits that scale with downtime severity
