How Australian contact centres move from containment to real resolution with agentic voice AI
For decades the phone-menu was the only form of voice automation most organisations knew: “press 1 for…”. Early voicebots improved on that with speech-to-text and keyword routing, but they still focused on one metric, containment, and too often left customers repeating themselves to agents. Today a new class of systems, agentic AI voicebots, are finally fulfilling the original promise: natural conversations that complete work, not just move callers around.
This BroadConnect guide explains what changed, why agentic voicebots matter for Australian contact centres, and how to plan a low-risk transition so you get measurable reductions in cost-to-serve and better customer outcomes.
From menus to agents: the change in one paragraph
Traditional IVR and first-generation voicebots relied on decision trees and keyword matching; they worked well for simple lookups but were brittle for real tasks. Agentic voicebots combine advanced natural language understanding, continuous context from CRM and conversation intelligence, and the ability to call backend APIs to act (book, cancel, refund, update). The result is fewer transfers, lower handle times and higher containment that actually equals resolution — not false economy.
Why Australian contact centres should care now
Investment in voice AI is accelerating globally and locally. The technology now supports secure on-shore deployments, integrates with cloud telephony and PBX systems, and works with modern observability and compliance requirements. For organisations running voice on business NBN or fibre, and who use SIP trunks or Microsoft Teams for calling, agentic voicebots plug into your existing stack — you don’t need a rip-and-replace. BroadConnect helps integrate AI voice agents with your Cloud PBX, SIP trunking and managed networking so rollouts are predictable and secure.
What changed technically (short overview)
Early voicebots were limited by keyword rules, static scripts and no true backend access. Agentic voicebots add three critical capabilities: continuous context (shared data across CRM, tickets and call transcripts), API-driven actions (writebacks and transactions) and reasoning/explainability (clear evidence behind each recommendation). When combined with on-shore transcription and call recording, these systems meet Australian privacy and compliance needs. See our options for compliant transcription and recording here: AI meeting transcription & call recording.

Side-by-side: generations at a glance
| Dimension | First-gen voicebots / IVR | Agentic AI voicebots |
| Input handling | Keypad + keyword matching | Full NLU (natural language understanding) |
| Backend actions | Rare; read-only | API calls, bookings, payments, updates |
| Escalation | Context often lost | Full transcript + intent + suggested actions |
| Containment metric | High but shallow | High and meaningful (task completion) |
| Adaptation | Manual updates | Continuous learning & policy controls |
| Compliance | Harder to prove | Built-in logging, redaction, on-shore options |
Measurable benefits to expect (realistic outcomes)
Contact centres adopting agentic voice AI typically see a combination of benefits: increased containment that resolves issues (not just deflects), lower average handle times for complex calls, improved forecastable staffing, and faster onboarding of seasonal demand. A practical set of targets to measure during a pilot includes containment rate, handover quality (first-touch resolution after escalation), average handle time and CSAT.
| KPI | Pilot target (typical) |
| Self-service completion (resolved without agent) | 40–60% |
| Reduction in average handle time | 15–30% |
| Decrease in repeat calls for same issue | 20–35% |
| Improvement in CSAT (post-call) | +5–12 pts |
BroadConnect can model expected ROI for your volumes and channels as part of a pilot — we combine voice agents with robust connectivity (business NBN/fibre and 4G failover) and managed SIP trunks to make outcomes reliable.

What to evaluate when choosing an agentic voicebot (practical checklist)
Don’t choose on demos alone — evaluate on architecture and outcomes. Key areas to assess:
- Data architecture & integration — Can the voice agent read and write to your CRM, billing and scheduling systems in real time? If not, it’s limited from day one. BroadConnect’s integration services help connect agents to CRM and PBX systems, including Microsoft Teams. See our Teams calling integrations.
- Explainability — Every recommendation should include the signals that drove it (e.g., “customer opened invoice link twice in 24h”). That’s essential for trust.
- Security & compliance — Does the vendor support on-shore transcript storage, tokenised payments and role-based access? Our cybersecurity and compliant transcription partners help here.
- Operational tooling — Can supervisors replay calls, test prompts, and roll back changes without dev cycles? Continuous A/B testing is table stakes.
- Telephony fit — Will it work over your SIP trunks, cloud PBX or Teams environment? BroadConnect supports deployment across Cloud PBX, SIP and Teams.
- Managed services & device provisioning — For multi-site rollouts you’ll want zero-touch provisioning and on-shore support; see our hardware & provisioning offerings.
Low-risk rollout path (recommended by BroadConnect)
Start small and scale fast. A typical staged program looks like this: 4–8 week pilot on one high-volume use case (e.g., appointment booking or billing enquiries), integrate backend APIs for actionability, measure containment/handovers for 4–6 weeks, refine prompts and escalation triggers, then expand to additional use cases and channels (voice → web chat → SMS). BroadConnect supports pilots end-to-end — from provisioning to analytics and compliance reporting. Learn about our contact centre solutions and managed services.
Common pitfalls and how to avoid them
Many projects fail not for technical reasons but for poor change management. Two recurring mistakes: (1) launching too many flows at once (instead, focus on high-value tasks) and (2) failing to instrument handovers for QA. Make sure agentic systems log decisions, keep auditable transcripts, and allow supervisors to tune policies without code. BroadConnect’s managed QA and analytics help keep pilots on track; explore our AI & automation services.
A short checklist for your pilot (copy into your runbook)
- Choose one repeatable task with measurable volume (appointments, status checks).
- Ensure full backend integration (CRM, calendar, billing).
- Enable secure recording + on-shore transcription for QA and compliance.
- Define success metrics before launch (containment, AHT, CSAT).
- Plan a 6–12 week tuning window with weekly reviews.
Final thoughts — from cost centre to customer-facing asset
Agentic voicebots are not about replacing humans; they’re about reallocating human skills to where they add most value. When automation completes tasks and hands over rich context for complex conversations, agents spend their time solving problems that require judgement and empathy. For Australian contact centres that need reliability, compliance and measurable ROI, the path is clear: adopt agentic AI incrementally, integrate it into your telephony and CRM stack, and instrument every handover.
If you’d like BroadConnect to help design or pilot an agentic voice rollout, we can map expected gains across your voice channels, provision handsets and SIP trunks, and run compliance-first transcription and analytics. Start here: Contact BroadConnect.
nging appointments, order status, account balance and payment. Build short self-service flows for those tasks and measure completion rates. Any flow with an error or abandonment above 3% should be reworked. Record calls and use transcripts to run two-week A/B tests on voice persona and prompt wording; small wording changes often yield big containment wins.
