Data from each vendor's pricing page and docs, checked October 2026.

What Is an IVR Solution?

An IVR (interactive voice response) solution is phone software that answers inbound calls and lets callers get answers, reach the right team, or complete tasks without an agent.

Traditional IVR uses touch-tone menus and recorded prompts. An AI IVR replaces the menu with a voice agent: callers just speak, and the agent answers, completes the task, or hands the call to a person with context.

For the wording itself, IVR script examples covers ten scripts you can copy and where each one breaks.

The shift matters because caller abandonment rates average 12-20% in most contact centers, and much of that abandonment happens inside the IVR itself. Modern AI IVR solutions aim to resolve calls entirely or route them intelligently, without forcing callers through a phone tree.

In-Depth Reviews: 8 Best IVR Solutions in 2026, Compared

1. Retell AI: Best for AI-Native IVR Replacement

What does it do? Replaces traditional IVR with LLM-powered voice agents that hold natural, multi-turn phone conversations and execute tasks in real time.

Who is it for? Contact center leaders, healthcare administrators, and operations teams replacing legacy IVR with conversational AI.

What sets Retell AI apart from the legacy IVRs on this list is the architecture. Instead of scripted menu trees, you build conversation flows with a drag-and-drop AI IVR builder that uses LLMs to understand callers in real time, and the agent recovers when a caller interrupts or changes topic. One medical billing customer completes about 70% of inbound calls end to end and collects about $280,000 a month.

Transfer and logging: Retell supports cold, warm and agentic warm transfer, and a warm transfer can play a private whisper message that briefs the human before the caller joins. After each call it stores the transcript, recording, summary, sentiment and any custom fields you define, and sends them by webhook or API or writes them to HubSpot, Salesforce or Zendesk.

Pros

• About 600ms end-to-end response latency (vendor-stated), with turn-taking that handles interruptions
• Pay-as-you-go pricing from $0.07 per minute, with no platform fees, seat minimums or contracts
• Bring-your-own LLM (GPT-4o, Claude, Gemini) and voice engine (ElevenLabs v3, OpenAI, Cartesia) for zero vendor lock-in
• SOC 2 Type II, HIPAA with self-service BAA portal, GDPR compliant, plus PII redaction and on-premise deployment options
• 20 free concurrent calls out of the box, scalable to enterprise-grade with custom concurrency

Cons

• No built-in workforce management or agent scheduling tools; you need a separate WFM platform if you run a blended AI-plus-human operation

Pricing Pay-as-you-go, from $0.07 per minute. $10 free credit to start. No platform fees, minimums or contracts. The rate depends on the LLM and voice engine you choose.

2. Five9: Best for Large Regulated Contact Centers

What does it do? Enterprise cloud contact center platform with IVR, ACD, predictive dialing, and AI-powered self-service across voice and digital channels.

Who is it for? Contact centers with 50+ agents in healthcare, financial services, and government verticals needing deep compliance coverage.

Five9's strength is its compliance depth. The platform supports HIPAA, PCI DSS, and SOC 2 certifications, and its 99.999% uptime SLA (five nines, hence the name) is among the highest in the industry. The Genius AI suite provides agent assist, call summaries, and transcription. However, the pricing structure is complex. The base Core plan starts at $159/user/month with a 50-seat minimum, which means a minimum annual commitment exceeding $95,000 before add-ons. IVR with speech recognition, CRM connectors, and advanced AI features all carry separate costs. According to industry data on contact center costs, US-based agents cost $28-$40/hour, making Five9's total cost of ownership competitive only at scale.

Transfer and logging: Five9 documents warm and cold transfers, and call variables travel with the call to the next agent. Agents apply a disposition to every call, and Five9's CRM adapter logs the interaction against the CRM record.

Pros

• 99.999% uptime SLA backed by geo-redundant architecture
• Deep compliance certifications covering HIPAA, PCI DSS, HITRUST, and SOC 2
• Strong predictive, power, and preview dialer for outbound campaigns
• Extensive CRM integrations with Salesforce, ServiceNow, Microsoft Dynamics

Cons

• 50-seat minimum excludes small and mid-size teams entirely
• IVR speech recognition is an add-on, not included in the base plan
• Complex pricing with many essential features sold separately

Pricing Core plan starts at $159/user/month (voice only). Digital plan at $119/user/month. Premium, Optimum, and Ultimate tiers require custom quotes. 50-seat minimum on all plans. Annual contracts standard.

3. Genesys Cloud CX: Best for Enterprise Omnichannel Orchestration

What does it do? Full-suite cloud contact center with drag-and-drop IVR flow builder, omnichannel routing, workforce engagement, and native AI across voice, chat, email, and social.

Who is it for? Large enterprises (200+ agents) that need unified customer journey orchestration across every channel.

The pricing is tiered from $75/user/month (CX 1, voice only) to $240/user/month (CX 4, full suite with AI). Telecom costs are separate. For a 100-agent contact center on CX 2 ($115/user/month), annual licensing alone runs $138,000 before telecom. Genesys includes AI Experience tokens and Agent Copilot in all tiers, which is more transparent than competitors that charge separately for AI. The IVR market is valued at $6.02 billion in 2026, and Genesys captures a significant share of the enterprise segment. Still, the platform is overkill for teams under 50 agents or those primarily needing AI-powered call handling rather than full contact center infrastructure.

Transfer and logging: Genesys supports consult (warm) and blind transfers. Agents tag each interaction with a wrap-up code, and the Salesforce and Zendesk integrations carry those codes into the CRM or helpdesk.

Pros

• Architect flow builder creates sophisticated IVR paths with visual drag-and-drop
• Predictive routing uses AI to match callers with the optimal agent
• Fair-use policy includes IVR minutes, API calls, and voice transcription in the seat price
• Native AI (Agent Copilot, bots, predictive engagement) included in all tiers

Cons

• CX 1 is voice-only; digital channels require upgrading to CX 2 at $115/user/month
• Telecom costs are separate and can add $60,000-$100,000/year for a 100-agent center
• Implementation typically takes 30-90 days with professional services

Pricing CX 1 at $75/user/month (voice only). CX 2 at $115/user/month (digital + voice). CX 3 at $155/user/month (adds WFM). CX 4 at $240/user/month (full AI suite). Billed annually. Telecom billed separately.

4. NICE CXone: Best for Workforce Optimization Paired with IVR

What does it do? Cloud contact center with 30+ communication channels, AI-powered IVR, workforce engagement management, and Enlighten AI analytics.

Who is it for? Operations leaders in 100+ agent environments who need scheduling, forecasting, and quality management tightly integrated with their IVR.

NICE CXone's differentiator is workforce engagement. The Enlighten AI suite scores 100% of calls automatically (compared to the 2-5% that manual QA teams typically review), providing sentiment analysis, compliance scoring, and performance benchmarks. Pricing starts at $71/user/month for digital-only and $94/user/month for voice. The Complete Suite at $209/user/month bundles everything including WFM and quality management. For organizations where agent attrition averages 30-45% annually, the workforce tools can deliver real ROI. But smaller teams will find the pricing steep and the Windows-only scripting tool frustrating.

Transfer and logging: Agents can consult or transfer to another agent, skill or team. Each interaction gets a disposition and optional tags for reporting.

Pros

• Enlighten AI scores every call for quality, compliance, and sentiment automatically
• Workforce management (scheduling, forecasting) tightly integrated with call data
• 30+ native communication channels in a single platform
• 60-day free trial, the most generous trial period on this list

Cons

• Studio scripting tool is Windows-only and requires proprietary knowledge
• Advanced AI features (Enlighten) require higher-tier plans at $155+/user/month
• Learning curve is significant for administrators new to the platform

Pricing Digital Agent at $71/user/month. Voice Agent at $94/user/month. Omnichannel at $110/user/month. Essential Suite at $135/user/month. Complete Suite at $209/user/month. Custom enterprise pricing available.

5. Talkdesk: Best for Mid-Market Teams Wanting a Visual IVR Builder

What does it do? Cloud contact center with Studio visual IVR builder, AI-powered routing, and industry-specific solutions for healthcare, banking, and retail.

Who is it for? Mid-market contact centers (20-200 agents) that want an intuitive IVR design experience without enterprise complexity.

Talkdesk's Industry Experience Clouds for healthcare and financial services include pre-built integrations (Epic for healthcare, core banking systems) and compliance features that speed deployment in regulated verticals. The platform scored 4.5/5 on Capterra based on 732 reviews, with users praising the interface but noting that the mandatory 3-year contract and add-on pricing structure can make total costs unpredictable. For teams that primarily need intelligent call routing and a clean IVR builder, Talkdesk delivers. But if you need AI-powered call handling that replaces agents rather than routing to them, a conversational AI platform will serve you better.

Transfer and logging: Talkdesk supports warm transfers, where the agent briefs the next person before handing over, and blind transfers. Agents pick a disposition in the wrap-up form, and Talkdesk adds it to the call log on the contact's profile.

Pros

• Studio IVR builder is genuinely intuitive with drag-and-drop flow design
• Industry Experience Clouds offer pre-built compliance and integrations for healthcare, banking, and retail
• 60+ native integrations including Salesforce, Zendesk, Slack, and Shopify
• 100% uptime SLA on the Elite plan

Cons

• AI features (Autopilot, Copilot) are paid add-ons even on the top-tier plan
• Mandatory 3-year contract at list pricing
• Digital channels require the $165/month Elite plan; lower tiers are channel-siloed

Pricing Digital Essentials at $85/user/month. Voice Essentials at $105/user/month. CX Cloud Elite at $165/user/month. Industry Experience Clouds priced via custom quote. 3-year contract standard.

6. NiCE Cognigy: Best for Global Enterprises Building Multilingual Voice Bots

What does it do? Enterprise conversational AI platform for building voice and chat agents with a low-code flow builder, LLM orchestration, and native integration with major CCaaS platforms.

Who is it for? Global enterprises (1,000+ agents) with in-house development teams that need multilingual voice bots deployed across multiple contact center platforms.

Cognigy is now NiCE Cognigy, part of NICE, which acquired it in September 2025. It positions itself as the AI layer that sits on top of existing CCaaS infrastructure. This makes it powerful for enterprises that already run Genesys, NICE, Avaya, or Amazon Connect and want to add conversational AI without ripping out their phone system. Clients include Bosch, Lufthansa, Mercedes-Benz, and Toyota. But the platform is not plug-and-play. Building production-grade voice bots typically requires developers familiar with intent design, API integrations, and LLM orchestration. For teams without engineering resources, the time-to-value is measured in months, not days.

Transfer and logging: A Handover to Human Agent node sends the conversation to Genesys, Salesforce, NiCE CXone and other contact centers, and for NiCE CXone it can pass the transcript as the first message. Each contact's context is stored for the session.

Pros

• Integrates as an AI layer on top of existing CCaaS (Genesys, NICE, Avaya, Amazon Connect)
• LLM orchestration allows mixing structured flows with generative AI responses
• Enterprise security: SOC 2, HIPAA, GDPR, on-premise and air-gapped deployment options

Cons

• Voice is not the primary modality; Voice Gateway requires separate configuration
• Requires developer resources for production-grade deployments; not a no-code tool in practice

Pricing Custom enterprise pricing.

7. PolyAI: Best for High-Containment Voice Assistants

What does it do? Managed conversational AI voice assistant purpose-built for phone-based customer service, designed to resolve calls without transferring to agents.

Who is it for? Hospitality, retail, and restaurant brands with high inbound call volume that want maximum call containment through a managed service.

PolyAI has built a strong reputation in hospitality and restaurant chains, where call patterns are repetitive and high-volume. Their proprietary voice models produce some of the most natural-sounding AI speech available. But the managed model means you are dependent on their team for updates, and the platform is not designed for the kind of complex, multi-system workflows that contact centers in healthcare or financial services typically need. Managed deployments use custom pricing, but you can sign up free and build and test agents yourself in Agent Studio.

Transfer and logging: PolyAI hands calls to a live agent over SIP and can pass caller context in SIP headers or through a Handoff API. Its Conversations API returns the full transcript plus the handoff destination and reason for each call.

Pros

• Proprietary voice models produce exceptionally natural-sounding speech
• High containment rates on repetitive, high-volume call patterns
• Purpose-built for phone conversations, not adapted from a chat platform
• Strong track record in hospitality and restaurant verticals

Cons

• Most deployments run with PolyAI's team involved; self-serve editing happens in Agent Studio
• Handoffs and custom logic need SIP and code-level setup (ADK)

Pricing Custom pricing for managed deployments. Free self-serve sign-up to build and test agents in Agent Studio.

8. Dialpad: Best for SMBs Wanting AI Call Routing Without CCaaS Complexity

What does it do? Cloud communications platform with AI-powered call routing, real-time transcription, and basic IVR for small to mid-size businesses.

Who is it for? SMBs and growing teams (5-50 agents) that need smart call handling without deploying a full contact center platform.

Dialpad's pricing is the most accessible on this list, starting at $27/user/month for the business plan and $95/user/month for the AI contact center. There are no seat minimums, and the platform includes real-time coaching, transcription, and sentiment analysis even on lower tiers. For SMBs handling 500-2,000 calls per month that need basic routing intelligence and AI-assisted agent tools, Dialpad is a strong fit. But organizations that need true conversational IVR, outbound campaigns, or enterprise compliance will outgrow it quickly.

Transfer and logging: Dialpad supports warm (ask first) and blind transfers. After a transfer, the receiving agent sets the call disposition, and each call leg gets its own AI transcript.

Pros

• Setup takes under an hour with no professional services required
• AI-powered transcription, sentiment analysis, and CSAT prediction included in all plans
• No seat minimums, making it accessible for teams of any size
• Pricing starts at $27/user/month, the lowest entry point on this list

Cons

• IVR builder is basic: menu trees only, no natural language understanding
• No outbound dialing, batch calling, or campaign management tools
• Limited compliance certifications compared to enterprise platforms

Pricing Business plan at $27/user/month. Pro at $35/user/month. AI Contact Center at $95/user/month. No minimums, monthly or annual billing.

How do AI IVR providers handle live-agent transfer?

Live-agent transfer in an AI IVR moves a caller from the voice agent to a human, with the context the human needs to carry on without starting over.

Cold transfer (or blind transfer) sends the call straight to a number or queue, and the AI drops off. The human starts with nothing unless data rides along in the call signal.

Warm transfer puts the caller on hold while someone briefs the human first, then connects them. In an AI IVR, the voice agent does the briefing.

Whatever the method, five things should reach the human:

• Who is calling: name, number and account or policy ID
• Why they called: the intent in a few words
• What already happened: details collected and steps the AI tried
• Why the AI is transferring: the caller asked, verification failed, or the request is out of scope
• A short summary or transcript the human can read in seconds

Also check what happens when nobody answers. A good setup returns the caller to the AI, a queue, voicemail or a callback instead of dropping the call.

Five9, Genesys Cloud CX, NICE CXone, Talkdesk and Dialpad document transfers from one human agent to another, so the briefing is a person talking. Retell AI, NiCE Cognigy and PolyAI document how the AI itself passes context at handoff.

How should an AI IVR log call outcomes?

Outcome logging in an AI IVR means every call ends with a structured record of why the person called, how the call ended, and what happened next.

Log at least these fields on every call:

• Intent: why the person called, as one value from a fixed list (billing, scheduling, claim status)
• Resolution: whether the AI finished the task, yes or no
• Transfer reason: why the AI handed off, if it did
• Disposition: the final outcome code, such as resolved, transferred, callback booked, abandoned or voicemail
• Transcript and recording: the full record for QA and disputes
• Caller details: IDs, dates or numbers the caller gave

Then send that record where your team works. The CRM puts the outcome on the contact, a webhook pushes it to your own systems the moment the call ends, and an analytics tool tracks containment and transfer rates over time.

Use fixed lists for intent and disposition. Free-text outcomes are hard to count, so you cannot see which flows resolve calls and which ones leak to agents.

In the contact center suites, an agent usually picks the disposition by hand. An AI IVR has to fill those fields itself, including on calls no human touches.

Retell AI does this with post-call analysis: after each call, an LLM reads the transcript and fills the fields you define, so a pick-list field can hold the intent or disposition with no agent input.

How I Chose the Best IVR Solutions

IVR Containment and Resolution Depth

I prioritized platforms that drive real call center automation by resolving calls inside the IVR rather than just routing them. A traditional IVR that sends 80% of callers to an agent is not saving you money. I compared how much of each call a platform can resolve without human intervention, based on its own docs.

Does a caller reach a live agent with context?

A good AI IVR transfers to a person without making the caller repeat themselves. I checked each vendor's docs for three things: whether it supports warm transfer (the agent is briefed before the caller joins) or only cold transfer, whether a summary or transcript moves with the call, and whether a failed transfer falls back to a queue, voicemail or callback.

How is every call outcome logged, and where does it go?

Outcome logging means each call ends with a record of what happened: the disposition (resolved, transferred, abandoned), the transcript, and any fields the caller gave, such as a policy number. I checked what each platform stores per call and where it sends that record: a CRM like Salesforce or HubSpot, a helpdesk like Zendesk, a webhook, or an export. An IVR that resolves a call but logs nothing leaves your team blind on which flows work.

Latency and Conversation Quality

Callers start to disengage after about 1.5 seconds of silence, so response time decides whether an AI IVR feels like a conversation or a slower phone tree. Latency figures in this list are vendor-stated.

Total Cost of Ownership

Per-seat pricing looks clean on a sales page but hides the real cost. A fair comparison counts base licensing, IVR add-ons, telephony, AI features, and implementation. Per-minute platforms charge for the calls AI handles; per-seat platforms charge for every licensed agent, whether calls come or not.

Compliance and Security

For healthcare, financial services, and insurance buyers, compliance is not optional. I verified each platform's certifications (SOC 2 Type I vs. Type II, HIPAA with or without BAA, PCI DSS) and checked whether compliance features like PII redaction and call recording encryption were included or sold as add-ons.

How do AI IVR platforms connect to your existing phone numbers?

Most AI IVR platforms connect to the numbers you already own through SIP trunking, so you keep your carrier and your published numbers. A cloud based IVR system sits behind the carrier: calls arrive on your number, the carrier routes them over a SIP trunk to the IVR, and transfers go back out the same way.

Bring your own number. Check whether the platform lets you import an existing number or forces you to buy one of theirs. Pointing an existing number at a SIP trunk is usually a smaller change than porting it to a new carrier.

SIP trunk support. Ask which carriers the vendor documents (Twilio, Telnyx, Vonage and others) and whether it supports SIP REFER for transfers, since that decides which caller ID the live agent sees.

DTMF keypad input. Callers still press keys to enter account numbers, dates of birth and PINs, because spoken digits are easy to mishear. An AI IVR should accept keypad input mid-conversation, and for outbound calls it should be able to press digits to get through another company's phone tree.

Retell connects through elastic SIP trunking or by dialing a call to its SIP endpoint, and you can import numbers from Twilio, Telnyx, Vonage or any carrier that supports SIP trunks (docs). Its agents can also navigate IVR menus with keypad presses.

Top Use Cases for IVR Solutions

Inbound call triage and routing: An AI voice agent answers every inbound call, understands caller intent through natural language, and routes to the right department or resolves the query, turning IVR into true conversational AI for customer service without human intervention. Organizations replacing DTMF menus with conversational AI report containment rates above 60%.

After-hours call handling: An AI answering service picks up calls 24/7, captures caller information, schedules callbacks, and handles urgent routing. This eliminates the voicemail black hole that costs service businesses an estimated 30% of after-hours leads.

Lead qualification and warm transfer: Inbound leads are qualified through multi-turn conversation, scored, and transferred to sales with full context. Lead qualification via voice AI replaces the manual SDR screen that most call centers run today, at a fraction of the per-lead cost.

Limitations and Challenges of IVR Solutions

Caller trust gap: Even the best AI voice agents face caller skepticism. A percentage of callers will always press zero or ask for a human, regardless of voice quality. Plan for warm transfer as a standard fallback.

Complex multi-system workflows: IVR solutions that need to query EHR systems, payment processors, and CRMs in real time during a call add latency at each integration point. Test end-to-end latency with your actual backend, not just the IVR in isolation.

Regulatory unpredictability: AI voice regulations are evolving. The FTC has increased scrutiny on AI-generated voice calls, and several states have pending legislation on AI disclosure requirements. Build disclosure scripts into your IVR flows now.

Accent and dialect performance: Speech recognition accuracy drops with heavy accents, regional dialects, and background noise. Test with callers from your actual customer base, not just standard American English.

Ongoing tuning requirements: No IVR deploys perfectly on day one. Budget for 2-4 weeks of tuning conversation flows, adjusting thresholds for transfer, and refining intent recognition based on real call data.

Try Retell AI

If your IVR sends callers through three layers of "press 1" before they reach anyone, Retell AI replaces that menu with a voice agent that resolves the call or hands it to a person with context.

• $10 free credit to test on real calls
• From $0.07 per minute, with no platform fees, seat minimums or contracts

FAQ

Which AI IVR providers support live agent transfer?

All eight platforms in this list can send a caller to a human, but they differ in whether the agent gets context. Retell AI documents warm transfer with a private briefing before the caller joins, plus agentic warm transfer. Five9, Genesys Cloud CX, Talkdesk and Dialpad document warm and blind transfers; NiCE Cognigy can pass the transcript at handover; PolyAI passes context in SIP headers. Ask any vendor for its transfer docs and check whether a summary or transcript moves with the call.

How do AI IVR systems log call outcomes?

AI IVR systems log each call as a record with the transcript, the outcome (resolved, transferred, abandoned) and any details the caller gave. The difference between platforms is where that record goes. Some keep it in their own reporting, some send it to a webhook, and some write it straight to a CRM or helpdesk. Retell AI stores a transcript, recording, summary, sentiment and custom fields for every call and can write them to HubSpot, Salesforce or Zendesk.

What is the difference between a warm and a cold transfer in an AI IVR?

In a cold transfer, the AI sends the call straight to a number or queue and drops off, so the human starts without context. In a warm transfer, the caller waits on hold while the AI briefs the human, then the AI connects them. Retell AI supports cold, warm and agentic warm transfer, where a second AI agent screens the human before connecting the caller.

Can an AI IVR write call outcomes to my CRM automatically?

Yes, if the platform has a native CRM sync or a webhook. Retell AI maps its post-call analysis fields to HubSpot, Salesforce, Dynamics 365, GoHighLevel and Zoho contacts and logs each call to the CRM. Five9 and Dialpad save the agent's disposition in the Salesforce Call Result field, and Genesys Cloud CX supports wrap-up codes in its Salesforce and Zendesk integrations.

Can an IVR solution handle high call volumes during peak periods?

Yes, but capacity varies dramatically by platform. Legacy per-seat CCaaS platforms are limited by the number of licensed agents. AI-native IVR solutions like Retell AI offer 20 free concurrent calls with scalability to thousands, handling volume spikes without licensing changes. For healthcare organizations that see 3-5x call spikes during open enrollment, this lets the system absorb a spike without new licenses.

How do IVR solutions integrate with existing PBX and phone systems?

Most modern IVR platforms and AI call bots connect via SIP trunking, which lets you route calls from your existing phone system (Avaya, Cisco, Mitel) to the AI IVR without replacing hardware. Retell AI supports SIP trunking with any telephony provider, including Twilio, Vonage, and Telnyx. Five9 and Genesys also support BYOC (bring your own carrier). The key question is whether you need a full rip-and-replace or can run the AI IVR alongside your existing system during a transition.

What is the typical ROI timeline for replacing a traditional IVR with AI?

Most organizations see measurable ROI within 60-90 days. The primary savings come from reduced agent handle time (AI resolves calls that previously required agents), lower abandonment (callers stay on the line when they get immediate responses), and 24/7 coverage without overtime. The math depends on how many calls AI resolves without a transfer: every resolved call saves the agent time it would have taken, while transferred calls cost both. Start with one high-volume call type, measure its resolution rate for 30 days, then expand.

Do IVR solutions meet HIPAA requirements for healthcare organizations?

Not all of them. HIPAA compliance requires a signed Business Associate Agreement (BAA), encryption in transit and at rest, access controls, and audit trails. Among the platforms in this list, Retell AI offers a self-service BAA portal with HIPAA compliance included at no extra cost. Five9, Genesys, and NICE CXone also support HIPAA, but compliance features may require higher-tier plans. Platforms with knowledge base capabilities can connect to EHR data while maintaining HIPAA-compliant data handling.

What happens when an IVR solution cannot understand a caller?

Failure handling separates production-grade IVR from demo-quality systems. The best platforms detect confusion signals (repeated questions, silence, explicit requests for help) and escalate gracefully. Retell AI's warm transfer passes full conversation context so the human agent knows exactly what was discussed. Check each vendor's transfer docs: some pass a summary to the agent, others drop the caller into a queue with no history. The comparison table above shows which is which.

Can IVR solutions support outbound calling campaigns?

Only some. Traditional CCaaS platforms (Five9, Genesys, NICE, Talkdesk) include outbound dialers for AI outbound calling campaigns. Among AI-native platforms, Retell AI offers batch calling with scalable concurrency and detailed outbound call center KPI conversion tracking, plus branded caller ID and verified phone numbers to maintain answer rates. If outbound IVR campaigns are a priority, verify that the platform supports predictive or power dialing before committing.

For the outbound side, outbound IVR calls covers where they still work and where a voice agent beats them.

How many languages can modern IVR solutions support?

Language support varies widely by platform. Retell AI supports 55 languages across 63 locale variants, each covered by both a speech-recognition and a text-to-speech provider, with multilingual auto-detect. For businesses serving multilingual populations, test multilingual conversational AI accuracy in your target languages specifically, not just menu comprehension.
