Omnichannel Contact Centre: Why Voice Alone Isn't Enough
Is Voice Still the Most Important Customer Channel?
Voice is not dead. It remains the preferred channel for complex, high-emotion, and high-value interactions. But the data is unambiguous: voice alone is no longer sufficient.
A 2025 study by McKinsey found that 65% of customers under 40 prefer to resolve issues through digital channels — webchat, messaging apps, email, or social media — before picking up the phone. Salesforce's State of the Connected Customer report (2025) goes further: 76% of consumers expect consistent interactions across all channels, and 73% say they will switch to a competitor after a single poor experience.
In Australia specifically, the Communications Alliance's 2025 consumer survey found that webchat usage for customer service enquiries increased by 48% between 2022 and 2025, while voice call volumes declined by 11% over the same period. The trend is not that voice is disappearing — it is that customers now choose the channel that suits the situation.
An omnichannel contact centre unifies all of these channels into a single platform. Agents handle voice calls, webchat, email, SMS, and social media messages from one interface, with full visibility into the customer's history regardless of which channel they used previously.
What Does "Omnichannel" Actually Mean?
The term is often used loosely, so it is worth being precise. There is a meaningful difference between multichannel and omnichannel:
- Multichannel means offering multiple channels (phone, email, chat) but managing them separately. An agent handling phone calls cannot see that the same customer sent an email yesterday. Each channel operates in its own silo.
- Omnichannel means unifying all channels into a single view. When a customer calls, the agent sees their previous webchat transcript, their email history, and any SMS exchanges — all in one place. The conversation is continuous across channels.
The distinction matters because customer frustration overwhelmingly stems from repetition. According to Harvard Business Review, 62% of customers report having to repeatedly explain their issue across channels as their top service complaint. Omnichannel eliminates this by giving agents complete context.
Which Channels Matter Most in 2026?
Not every channel deserves equal investment. The right mix depends on your customer base, industry, and the nature of your enquiries. Here is how the major channels perform across key metrics.
| Channel | Customer Preference (2025) | Avg. Handle Time | Cost Per Interaction | Best For |
|---|---|---|---|---|
| Voice | 35% overall, 52% for complex issues | 6-8 minutes | $8-$15 AUD | Complex enquiries, complaints, high-value sales |
| Webchat | 28% overall, 41% for simple enquiries | 4-6 minutes | $3-$6 AUD | Quick questions, order status, troubleshooting |
| 18% overall | 24-48 hours resolution | $4-$8 AUD | Detailed enquiries, documentation, non-urgent issues | |
| SMS/Messaging | 12% overall, growing fastest | 2-4 minutes | $1-$3 AUD | Appointment reminders, notifications, brief exchanges |
| Social Media | 7% overall | 1-4 hours resolution | $5-$10 AUD | Public-facing issues, brand management, younger demographics |

The cost differential is significant. A webchat interaction costs roughly half of a voice call, and an agent can handle 2-3 concurrent chat sessions compared to one voice call. For businesses processing thousands of enquiries per month, shifting even 20% of simple voice calls to webchat can deliver material savings.
How Does Webchat Change the Customer Experience?
Webchat is the fastest-growing customer service channel in Australia, and for good reason. It combines the immediacy of a phone call with the convenience of text-based communication.
Proactive Chat
Modern webchat is not just reactive. Proactive chat triggers engage visitors based on behaviour — time on page, pages visited, cart value — and offer assistance before the customer asks. Research from Forrester shows that proactive chat increases conversion rates by 15-25% on e-commerce sites and reduces cart abandonment by up to 30%.
Chatbot-to-Agent Handoff
The most effective webchat implementations use AI chatbots to handle routine enquiries (operating hours, order tracking, FAQs) and seamlessly hand off to a live agent when the conversation exceeds the bot's capability. The customer does not restart the conversation — the agent receives the full chat transcript and continues where the bot left off.
What Role Does SMS Play in a Contact Centre?
SMS is often overlooked, but it is remarkably effective for specific use cases:
- Appointment reminders — Australian healthcare providers using SMS reminders report a 26% reduction in no-shows (Australian Digital Health Agency, 2025)
- Delivery notifications — proactive updates reduce inbound "where is my order?" calls by 30-40%
- Survey and feedback collection — SMS surveys achieve 40% response rates compared to 10-15% for email surveys
- Two-factor authentication — secure verification for account access and transactions
In an omnichannel contact centre, SMS is not a standalone tool. It is integrated into the same agent interface as voice and chat, meaning an agent can send an SMS follow-up after a voice call without switching applications. The conversation history is unified.
How Does Social Media Fit Into the Contact Centre?
Social media customer service is unique because it is public by default. A complaint on Facebook or Instagram is visible to thousands of potential customers, making response time and quality critical for brand reputation.
According to Sprout Social's 2025 Index, 76% of consumers expect a response from a brand on social media within 24 hours, and 36% expect a response within one hour. Failing to respond is worse than responding slowly — customers who receive no response are 50% more likely to share their negative experience publicly.
An omnichannel contact centre pulls social media interactions into the same queue as voice and chat. This means social messages are not left to the marketing team to notice — they are routed, prioritised, and tracked with the same discipline as a phone call.
What About AI and Analytics in Omnichannel?
AI is not replacing agents — it is making them more effective. In the context of omnichannel contact centres, AI delivers value in several areas.
Sentiment Analysis
AI analyses the tone and language of customer interactions across all channels in real time. Supervisors receive alerts when a conversation turns negative, enabling intervention before a complaint escalates. Platforms like XIMA CCaaS include built-in sentiment analysis that scores interactions and flags those requiring attention.
Intelligent Routing
AI-powered routing goes beyond skills-based assignment. It considers the customer's history, the nature of their enquiry (detected via natural language processing), their sentiment, and agent specialisation to match each interaction with the best-suited agent. McKinsey reports that AI-enhanced routing improves first-contact resolution by 12-18%.
Automated Summarisation
After each interaction, AI generates a summary — key issues raised, actions taken, follow-ups required — and attaches it to the customer record. This saves agents 30-60 seconds per interaction on after-call work and ensures accurate context for future interactions.
How Do You Implement Omnichannel Without Disruption?
The shift to omnichannel does not need to be a single big-bang deployment. A phased approach is both lower-risk and more practical.
- Voice and Webchat (Weeks 1-4) — Start with your existing voice infrastructure and add webchat. Train a small group of agents on chat handling before rolling out to the full team.
- Email Integration (Weeks 4-8) — Bring email enquiries into the same platform with auto-acknowledgement and SLA-based routing rules.
- SMS and Social (Weeks 8-12) — Add SMS for proactive notifications and two-way messaging. Integrate social media channels, starting with your highest-volume platform.
- AI and Automation (Weeks 12-16) — With all channels flowing through a single platform, introduce AI chatbots, sentiment analysis, and automated workflows.
PCONNECT's approach to omnichannel deployment follows this phased model, using platforms like XIMA CCaaS that support all channels natively. Each phase is deployed, stabilised, and measured before the next begins.
Frequently Asked Questions
Do my agents need to handle all channels simultaneously?
No. Most omnichannel platforms allow you to assign agents to specific channels based on their skills and preferences. An experienced agent might handle voice and chat concurrently, while a newer agent starts with email only. The platform manages the blending and ensures agents are not overwhelmed.
Will adding digital channels reduce my call volume?
Typically, yes. Businesses that implement webchat alongside voice see a 15-25% reduction in voice call volume within six months, as customers self-select the most convenient channel.
What infrastructure do I need for omnichannel?
If you already have a cloud contact centre for voice, adding digital channels is a configuration exercise, not an infrastructure project. The same platform, same agent desktops, and same internet connections support all channels.
Can omnichannel work for small teams?
Absolutely. A team of five agents can benefit from omnichannel by handling chat and email during quiet voice periods, ensuring productive use of agent time. The cost of adding digital channels to an existing cloud contact centre is typically $10-$30 per agent per month — a modest investment for the flexibility and coverage it provides.
