Enterprise AI Voice Platform: What Large Organizations Need in 2026

Enterprise AI Voice Platform: What Large Organizations Need in 2026

Enterprise AI voice is a fundamentally different discipline from small-business voice automation. The gap is not incremental — it is structural. An SMB deploying an AI voice agent to handle 500 calls per month faces a different category of problem than an enterprise routing 100,000+ calls per month across multiple departments, geographies, and regulatory jurisdictions.

The stakes are proportionally different as well. When a Fortune 500 company deploys conversational AI for business at scale, a 15-minute outage can mean thousands of dropped customer interactions, potential regulatory violations, and measurable revenue impact. When compliance fails, the consequences are not a slap on the wrist — they are eight-figure fines, consent decrees, and C-suite accountability.

This guide is written for the people who own these decisions: CTOs, VPs of Engineering, IT procurement leads, and contact center operations directors. It covers the 12 non-negotiable requirements for an enterprise AI voice platform, the architecture that makes enterprise-grade performance possible, a rigorous build-vs-buy analysis, a procurement scoring framework, and a phased migration plan for moving from legacy systems to AI-native voice infrastructure.

Why Enterprise AI Voice Is Different from SMB Solutions

The surface-level function is the same: an AI agent answers the phone, understands the caller, and resolves the request. Beneath that surface, enterprise deployments face five categories of complexity that SMB platforms are not designed to handle.

Scale: 100,000+ Calls Per Month

At enterprise volumes, every architectural shortcut becomes a failure point. Latency that is imperceptible at 500 calls/month compounds into degraded experience at 100,000+. Connection pooling, queue management, concurrent session limits, and telephony carrier capacity all require deliberate engineering.

An enterprise AI voice platform must handle burst traffic — Monday morning spikes, promotional campaign surges, seasonal peaks — without degradation. This demands auto-scaling infrastructure, not fixed-capacity deployments.

Compliance: SOC 2, HIPAA, PCI-DSS, GDPR

Compliance is not a checkbox. For enterprises in healthcare, financial services, insurance, and government, compliance is a condition of doing business. An enterprise AI voice platform that cannot produce a SOC 2 Type II report, sign a Business Associate Agreement (BAA), or demonstrate PCI-DSS Level 1 compliance is disqualified before the technical evaluation begins.

Regulatory requirements also dictate data residency, retention policies, encryption standards, and audit logging capabilities. These are not features — they are table stakes.

Integration: Legacy Systems and Custom CRMs

Enterprises do not operate on a single SaaS stack. They operate on decades of accumulated systems: mainframe-backed databases, custom-built CRMs, proprietary ERP systems, on-premise telephony infrastructure, and middleware layers connecting all of it. An enterprise AI voice platform must integrate with what exists, not demand that the enterprise rebuild around the platform.

This requires robust APIs, webhook architectures, pre-built connectors for major systems (Salesforce, HubSpot, Microsoft Dynamics, ServiceNow, SAP), and the flexibility to build custom integrations for proprietary systems.

SLA Requirements: 99.99% Uptime Is the Baseline

For a contact center handling 100,000+ calls per month, 99.9% uptime means approximately 43 minutes of downtime per month — potentially hundreds of missed calls. Enterprise buyers require 99.99% uptime SLAs with financial penalties for non-compliance, transparent incident reporting, and documented disaster recovery procedures.

Multi-Department Deployment

Enterprise deployments rarely serve a single use case. The initial deployment may be customer service, but the roadmap includes sales, HR, finance, and operations. The platform must support multiple agents with distinct personas, knowledge bases, and integration points — all managed under a unified administration layer with department-level access controls.

The 12 Non-Negotiable Requirements for Enterprise AI Voice Platforms {#the-12-non-negotiable-requirements}

After evaluating dozens of enterprise deployments, these are the 12 requirements that separate enterprise-grade platforms from scaled-up SMB tools. Failing on any one of these is grounds for disqualification in a serious enterprise procurement process.

1. SOC 2 Type II Certification

SOC 2 Type II is not a point-in-time assessment. It is an ongoing audit that verifies a platform's security controls have been operating effectively over a minimum period (typically 6-12 months). It covers five trust service criteria: security, availability, processing integrity, confidentiality, and privacy.

Why it matters: SOC 2 Type II is the baseline security validation that enterprise security teams and procurement offices require. Without it, your vendor will not survive the security review.

What to verify: Ask for the most recent SOC 2 Type II report. Confirm the audit period, the auditing firm, and whether any exceptions were noted. A clean report from a reputable firm (not a boutique auditor) is what you need.

2. HIPAA Compliance (with BAA)

For any enterprise in healthcare, health insurance, or adjacent industries, the AI voice platform will process Protected Health Information (PHI). HIPAA compliance requires technical safeguards (encryption at rest and in transit, access controls, audit logging), administrative safeguards (workforce training, incident response procedures), and a signed Business Associate Agreement (BAA).

What to verify: Request the BAA template. Review whether the vendor's architecture supports PHI data segregation, whether call recordings containing PHI are encrypted and access-controlled, and whether the vendor has a documented breach notification process.

3. PCI-DSS Compliance for Payment Handling

If the AI voice agent will handle any payment card information — collecting credit card numbers, processing payments, verifying card details — PCI-DSS compliance is mandatory. This applies to collections calls, billing inquiries, and any transaction that involves cardholder data.

What to verify: Confirm the vendor's PCI-DSS compliance level. Level 1 (the highest) is required for platforms processing over 6 million transactions annually. Verify whether the platform supports DTMF masking (so card numbers are entered via keypad, not spoken), tokenization, and secure data vaulting.

4. GDPR/CCPA Data Privacy Controls

For enterprises operating in the EU or serving EU residents, GDPR compliance is non-negotiable. For those operating in California (or increasingly, other US states with privacy laws), CCPA/CPRA compliance is required. These regulations mandate specific controls around consent management, data access requests, right to deletion, data portability, and purpose limitation.

What to verify: Confirm the platform supports configurable data retention policies, automated data subject access request (DSAR) fulfillment, consent logging, and data residency controls (ability to keep data within specific geographic regions).

5. 99.99% Uptime SLA

99.99% uptime means a maximum of 4.38 minutes of downtime per month. Achieving this requires redundant infrastructure across multiple availability zones (minimum) or regions, automated failover, health monitoring with sub-minute detection, and a proven track record.

What to verify: Request the historical uptime data for the past 12 months. Review the SLA terms — specifically the measurement methodology (how is uptime calculated?), exclusions (what counts as "scheduled maintenance"?), and financial remedies (service credits, refunds).

6. Sub-500ms Response Latency at Scale

Conversational AI for business demands natural response times. Human conversational turn-taking expects responses within 300-700ms. At enterprise scale, maintaining sub-500ms latency requires optimized inference pipelines, edge-deployed models, intelligent caching, and connection keep-alive strategies across the entire chain: telephony ingress, speech-to-text, LLM processing, text-to-speech, and telephony egress.

What to verify: Request P50, P95, and P99 latency metrics — not just averages. A platform that averages 400ms but hits 2,000ms at P99 will deliver poor experiences for 1 in 100 callers, which at enterprise volumes means hundreds of degraded interactions daily.

7. Multi-Tenant Architecture

Enterprise deployments require logical isolation between departments, business units, and — in some cases — end clients. Multi-tenant architecture ensures that one department's traffic spike does not degrade another's performance, that data access is strictly scoped, and that configuration changes in one tenant cannot affect another.

What to verify: Understand the isolation model. Is it namespace-level isolation, database-level isolation, or infrastructure-level isolation? For regulated industries, database-level or infrastructure-level isolation may be required.

8. SSO and RBAC (Role-Based Access Control)

Enterprise platforms must integrate with existing identity providers (Okta, Azure AD, Ping Identity) via SAML 2.0 or OIDC. Role-based access control must support granular permissions: agent configuration, analytics viewing, call recording access, billing management, and administrative functions should all be independently assignable.

What to verify: Confirm SSO integration with your specific identity provider. Review the RBAC model — how many default roles exist, can custom roles be created, and can permissions be scoped to specific departments or tenants?

9. Enterprise CRM Integration (Salesforce, HubSpot, Microsoft Dynamics)

The AI voice agent must read from and write to your CRM in real time. This means bi-directional data flow: pulling customer context before and during the call, and pushing call outcomes, notes, disposition codes, and updated records back to the CRM after the call.

What to verify: Request a technical architecture document for the specific CRM integration you need. Confirm whether the integration is native (built-in), middleware-based (via Zapier, Workato, or similar), or API-based (requiring custom development). Native integrations deliver the best latency and reliability.

10. Custom LLM Fine-Tuning Capabilities

Generic language models produce generic responses. Enterprise deployments require fine-tuning capabilities: training the model on your specific terminology, products, policies, compliance language, and brand voice. This goes beyond prompt engineering — it includes the ability to fine-tune underlying models on proprietary datasets.

What to verify: Understand the fine-tuning workflow. Can you provide training data? What format is required? How long does fine-tuning take? Is there a validation pipeline to test fine-tuned models before production deployment? Can you A/B test fine-tuned vs. base models?

11. On-Premise / VPC Deployment Options

Some enterprises — particularly in financial services, government, and defense — cannot send voice data to a multi-tenant cloud. They require on-premise deployment or deployment within a dedicated Virtual Private Cloud (VPC) in their own cloud account.

What to verify: Confirm whether the vendor offers VPC deployment, dedicated single-tenant cloud deployment, or full on-premise deployment. Understand the operational model: who manages updates, scaling, and monitoring in each deployment option?

12. Dedicated Customer Success and 24/7 Support

Enterprise deployments are not self-serve. They require dedicated customer success managers, solutions architects for initial deployment, 24/7 technical support with defined escalation paths, and quarterly business reviews.

What to verify: Confirm the support SLA — response times for severity 1 (production down), severity 2 (degraded performance), and severity 3 (general issues). Understand whether support is in-house or outsourced, and whether your account will have a named CSM.

How Enterprise AI Voice Platforms Work

Understanding the architecture is critical for evaluating platforms. An enterprise-grade AI voice platform operates as a multi-stage pipeline with horizontal scaling at every layer.

Architecture Overview

Caller → Load Balancer (geo-distributed)
          → Telephony Gateway (SIP/PSTN ingress, carrier failover)
            → Speech-to-Text Cluster (streaming STT, multi-language)
              → LLM Routing Layer (intent classification, model selection)
                → LLM Inference Cluster (response generation, RAG pipeline)
              → Text-to-Speech Cluster (neural TTS, voice selection)
            → Telephony Gateway (audio egress)
          → Analytics Pipeline (real-time dashboards, call scoring, QA)
        → CRM / Integration Layer (bi-directional data sync)

Key Architectural Principles

Horizontal Scaling: Every component in the pipeline scales independently. A traffic surge does not require scaling the entire system — only the bottleneck layer (typically STT or LLM inference) scales up.

Failover and Redundancy: Enterprise platforms deploy across multiple availability zones and, ideally, multiple regions. If an entire availability zone fails, traffic routes to the surviving zones with no caller-perceptible interruption.

Multi-Region Deployment: For global enterprises, voice traffic should be processed in the region closest to the caller. This reduces latency (audio does not cross oceans), satisfies data residency requirements, and provides geographic redundancy.

Streaming Architecture: Enterprise-grade STT and TTS operate in streaming mode, not batch mode. The STT system begins processing audio as soon as the first packet arrives, and the TTS system begins generating audio before the full response text is available. This parallelism is what achieves sub-500ms end-to-end latency.

Analytics Pipeline: Every call generates structured data: transcripts, intent classifications, sentiment scores, resolution status, latency metrics, and cost data. This feeds into real-time dashboards for operations teams and batch analytics for strategic planning.

Enterprise Use Cases by Department

Enterprise AI voice platforms serve far more than customer service. The most successful deployments expand across the organization, with each department benefiting from purpose-built agents.

Customer Service

Customer service is the natural starting point — it typically represents the highest call volume and the most obvious ROI.

• Tier 1 deflection: Handling routine inquiries (order status, account balance, business hours, return policies) without human involvement. Enterprise contact centers report 60-80% Tier 1 deflection rates with well-configured AI agents.
• Callback scheduling: When an issue requires human follow-up, the AI agent schedules a callback at a time convenient for the customer, eliminating hold time and improving satisfaction.
• FAQ handling: Dynamic FAQ resolution using retrieval-augmented generation (RAG) against the enterprise knowledge base. Unlike static IVR, the AI agent understands intent variations and provides contextual answers.
• Multi-language support: Enterprise AI call center agents handle calls in 30+ languages without requiring language-specific human agents.

Sales

An AI call center agent deployed for sales operates as a force multiplier for the human sales team.

• Lead qualification at scale: Inbound leads are called within minutes, qualified against defined criteria (budget, authority, need, timeline), and routed to the appropriate sales representative with a complete qualification summary.
• SDR augmentation: AI handles the top-of-funnel outreach that would otherwise require a large SDR team — initial contact, interest qualification, and meeting scheduling.
• Meeting booking: The AI agent accesses sales representatives' calendars in real time and books qualified meetings directly, eliminating the back-and-forth of scheduling.

HR

Human resources departments face high call volumes for routine inquiries that AI handles exceptionally well.

• Candidate screening: Initial phone screens for high-volume roles (retail, hospitality, logistics) where the AI agent verifies basic qualifications, availability, and interest before routing qualified candidates to recruiters.
• Benefits inquiries: Open enrollment generates massive call volume. AI agents answer benefits questions, guide employees through plan selection, and escalate complex scenarios to benefits specialists.
• Employee hotline: IT helpdesk, facilities requests, PTO balance inquiries, and policy questions — all high-frequency, low-complexity interactions well suited for AI.

Finance

Finance departments deploy AI voice for revenue-impacting processes.

• Collections: AI agents handle early-stage collections calls with consistent compliance adherence — always delivering required disclosures, never violating FDCPA regulations. Enterprise collections operations report 15-25% improvement in right-party contact rates with AI-initiated outreach.
• Payment processing: Secure, PCI-compliant payment collection over the phone, using DTMF entry for card numbers to avoid speaking sensitive data.
• Account inquiries: Balance checks, statement requests, transaction history — high-volume interactions that require CRM integration but minimal decision-making.

Operations

Operations teams use AI voice for coordination and communication at scale.

• Dispatch: Automated dispatch calls to field service technicians, delivery drivers, and contractors — confirming availability, providing job details, and updating scheduling systems.
• Scheduling: Shift confirmations, schedule change notifications, and availability polling across large workforces.
• Vendor management: Purchase order confirmations, delivery scheduling, and routine vendor communications.

Build vs. Buy: The Enterprise AI Voice Decision

This is the most consequential decision in the enterprise AI voice journey. The analysis is not close — but it is important to understand why.

The Build Path

Building an enterprise AI voice platform from components (Twilio for telephony, Deepgram or Whisper for STT, OpenAI or Anthropic for LLM, ElevenLabs or PlayHT for TTS) requires:

And this assumes the build goes according to plan. In practice, enterprise voice systems involve edge cases that consume disproportionate engineering time: handling background noise, managing interruptions, dealing with accented speech, recovering from STT errors gracefully, and maintaining natural conversational flow.

The timeline is equally problematic. Twelve to eighteen months from project kickoff to production deployment means 12-18 months of lost opportunity — calls that could have been automated but were not.

The Buy Path

Purchasing an enterprise AI voice platform:

Time to production: 4-8 weeks for initial deployment, with iterative improvement thereafter.

The Verdict

Building makes sense only when: (a) voice AI is your core product, (b) you have unique technical requirements that no vendor can meet, or (c) regulatory constraints prohibit any third-party data processing. For virtually all other enterprises, buying is the correct decision — it delivers faster time to value, lower total cost, and access to a vendor's ongoing R&D investment.

Evaluating Enterprise AI Voice Platforms: A Procurement Framework

Use this weighted scoring matrix to evaluate vendors systematically. The weights reflect the priorities of enterprise buyers managing high-volume, regulated environments.

How to Run the Evaluation

1. RFP phase: Send a structured RFP to 3-5 vendors covering all 12 non-negotiable requirements. Eliminate any vendor that cannot meet the compliance requirements.

2. Technical proof of concept: With 2-3 finalists, run a controlled POC. Deploy each platform against the same 500 recorded calls (from your actual call data). Measure resolution rate, latency, voice quality (via human evaluation), and integration accuracy.

3. Load testing: Simulate peak traffic (2x your projected maximum concurrent calls) and measure performance degradation.

4. Security review: Your information security team reviews the vendor's SOC 2 report, penetration test results, and architectural documentation.

5. Reference calls: Speak with 2-3 existing enterprise customers of each vendor — ideally in your industry.

6. Contract negotiation: Negotiate SLA terms, data processing agreements, exit clauses, and pricing commitments.

Total Cost of Ownership: Enterprise AI Voice

TCO analysis must account for all direct and indirect costs over a 3-year horizon, compared against the status quo (typically a BPO/outsourced call center or an in-house agent team).

AI Voice Platform TCO (3-Year, 100,000 Calls/Month)

Traditional Call Center TCO (3-Year, 100,000 Calls/Month)

Net Savings

3-year savings: $15,855,000 (83.6% cost reduction)

Even accounting for conservative assumptions — lower AI resolution rates, higher per-minute costs, additional integration work — the savings consistently exceed 60% in enterprise environments. The ROI case for an enterprise AI voice platform is not marginal. It is transformational.

The opportunity cost is equally significant. Every month of delayed deployment is approximately $400,000+ in avoidable BPO spend for an operation at this scale.

Migration Planning: Moving from Legacy Systems to AI Voice

Migrating from a legacy contact center to an AI voice platform is a change management challenge as much as a technical one. A phased approach minimizes risk and builds organizational confidence.

Phase 1: Pilot (Weeks 1-8)

Scope: Single use case, single department, limited traffic (5-10% of volume for the selected use case).

Objective: Validate voice quality, resolution rate, integration accuracy, and caller satisfaction in a controlled environment.

Key activities:

• Deploy AI agent for one well-defined use case (e.g., appointment scheduling or order status)
• Route 5-10% of relevant calls to the AI agent, with the remainder continuing to human agents
• Measure: resolution rate, average handle time, caller satisfaction (post-call survey), escalation rate, latency
• Iterate on agent configuration based on call recordings and transcript analysis

Success criteria: Resolution rate above 75%, caller satisfaction within 10% of human agent baseline, zero compliance incidents.

Phase 2: Department Rollout (Weeks 9-20)

Scope: Full deployment for the pilot department, expanding to 2-3 additional use cases.

Objective: Prove the platform at departmental scale and establish operational processes for ongoing management.

Key activities:

• Increase AI traffic to 50-80% of volume for qualified call types
• Deploy additional agents for related use cases within the same department
• Establish internal operations team: agent configuration, QA review, escalation management
• Integrate with CRM, ticketing, and analytics systems
• Train human agents on their evolving role: handling escalations, providing AI feedback, managing exceptions

Success criteria: Resolution rate above 80% for target call types, operational processes documented and staffed, integration functioning reliably.

Phase 3: Enterprise Scale (Weeks 21-36)

Scope: Cross-department deployment, full production traffic, complete legacy system decommissioning.

Objective: Achieve enterprise-wide AI voice coverage with established governance.

Key activities:

• Deploy AI agents for sales, HR, finance, and operations use cases
• Route 100% of qualified traffic through the AI platform (with human escalation paths)
• Implement enterprise governance: change management processes, QA frameworks, compliance auditing
• Negotiate volume-based pricing with the platform vendor
• Decommission or downsize legacy BPO relationships
• Establish quarterly business review cadence with the vendor

Change management considerations:

• Communicate early and transparently with affected staff
• Redefine human agent roles toward high-complexity, high-value interactions
• Provide reskilling opportunities for agents transitioning to AI operations, QA, or escalation specialist roles
• Celebrate early wins to build organizational momentum

Risk Mitigation Strategies

Enterprise AI voice deployments carry real risks. Acknowledging and planning for these risks is what separates successful deployments from costly failures.

Human Escalation Paths

Every AI voice agent must have clearly defined escalation triggers — conditions under which the call is immediately transferred to a human agent. These include:

• Caller explicitly requests a human ("Let me speak to someone")
• Sentiment detection indicates frustration or distress beyond a defined threshold
• The AI agent fails to understand the caller after 2-3 attempts
• The call involves a scenario outside the agent's defined scope
• Compliance-sensitive situations requiring human judgment

Escalation must be seamless: the human agent receives the full conversation transcript and context, so the caller never repeats themselves.

Real-Time Monitoring

Enterprise deployments require live dashboards showing:

• Active concurrent calls
• Real-time resolution rate (rolling 1-hour window)
• Latency metrics (P50, P95, P99)
• Escalation rate by reason code
• Error rates (STT failures, TTS failures, integration errors)

Alerting thresholds should trigger automated notifications when any metric deviates from baseline by more than a defined margin.

A/B Testing

Before deploying any significant change to an AI agent — new prompt, updated knowledge base, fine-tuned model, modified escalation logic — run an A/B test. Route a percentage of traffic to the updated agent and compare performance metrics against the control. Only promote changes that demonstrate statistically significant improvement.

Gradual Traffic Shifting

Never switch 100% of traffic to a new agent or configuration simultaneously. Use gradual traffic shifting (canary deployments): 5% on day one, 25% on day three, 50% on day five, 100% on day seven — with automatic rollback if key metrics degrade beyond thresholds.

Disaster Recovery

Maintain a documented and tested disaster recovery plan:

• If the AI platform experiences a total outage, calls route to a backup IVR or human agent queue within 30 seconds
• Backup telephony carrier is pre-configured and tested monthly
• Call recordings and transcripts are replicated to a secondary storage location
• Recovery time objective (RTO): under 5 minutes. Recovery point objective (RPO): zero data loss for in-flight calls

Frequently Asked Questions

How long does an enterprise AI voice platform deployment take?

Plan for 4-8 weeks for the initial pilot deployment (single use case, limited traffic). A full department rollout typically takes an additional 8-12 weeks. Enterprise-wide deployment, including multi-department expansion and legacy system decommissioning, typically spans 6-9 months. The primary variables affecting timeline are integration complexity and internal change management processes, not the platform itself.

What is the minimum call volume where enterprise AI voice makes financial sense?

The financial case becomes compelling at approximately 10,000 calls per month, where the cost per call for AI ($0.20-$0.50 fully loaded) versus human agents ($4.00-$8.00) generates meaningful savings. At 50,000+ calls per month, the ROI is typically 300-500% in the first year. Below 5,000 calls per month, a standard business-tier platform (not enterprise) is usually more cost-appropriate.

Can an enterprise AI voice platform handle regulated industries (healthcare, financial services)?

Yes, but only if the platform meets the compliance requirements specific to your industry. For healthcare, this means HIPAA compliance with a signed BAA, encryption of all PHI, and access controls on call recordings. For financial services, this means PCI-DSS compliance for payment handling, SOC 2 Type II certification, and adherence to FINRA or OCC regulations as applicable. Always verify compliance certifications directly — do not accept marketing claims without audited documentation.

How do enterprise AI voice platforms handle multiple languages?

Modern platforms support 30+ languages through multilingual STT and TTS models. The AI agent can detect the caller's language automatically and switch languages mid-call. For enterprise deployments, verify that the specific languages you need are supported with production-quality accuracy — some platforms list languages as "supported" when accuracy is significantly lower than their primary language models.

What happens when the AI cannot handle a call?

Properly configured enterprise platforms transfer calls to human agents with full context: the conversation transcript, extracted intent, customer data pulled from the CRM, and the reason for escalation. The human agent picks up the conversation without requiring the caller to repeat any information. Escalation rates vary by use case — expect 15-25% for general customer service, 30-40% for complex sales scenarios, and 5-10% for simple transactional calls.

How do enterprise AI voice platforms integrate with existing telephony infrastructure?

Integration typically occurs at the SIP trunk level. The AI platform either receives calls via SIP transfer from your existing PBX/contact center platform, or it replaces the telephony layer entirely with its own carrier relationships. Most enterprise deployments start with SIP transfer (lower risk, easier rollback) and migrate to direct carrier integration as confidence builds. Platforms like QuickVoice support both models and provide dedicated telephony engineering support during implementation.

What level of customization is possible for the AI voice agent?

Enterprise platforms offer extensive customization: voice selection (including custom voice cloning), conversation flow design, knowledge base configuration, LLM fine-tuning on proprietary data, custom integration logic, and branded caller experience. The agent can be configured to reflect your brand's tone, terminology, and policies precisely. On QuickVoice, all of this is configurable through the no-code interface, with API-level access available for programmatic management.

How do we measure the success of an enterprise AI voice deployment?

Track these primary KPIs: resolution rate (percentage of calls fully handled by AI without human intervention), average handle time, caller satisfaction (post-call survey or sentiment analysis), escalation rate and reason distribution, cost per call (AI vs. human baseline), first-call resolution rate, and latency metrics. Establish baselines during the pilot phase and measure improvement through department rollout and enterprise scale. Expect resolution rates to improve by 10-15 percentage points in the first 90 days as the system learns from real interactions and configuration is optimized.
