1. What Is Azure Communication Services with Direct Routing?

Azure Communication Services (ACS) is Microsoft's cloud-native platform for voice, video, chat, and SMS. It delivers enterprise telephony as a managed cloud service, no physical hardware, no on-premise servers, no PBX licences to maintain.

Direct Routing is the technology that connects Azure Communication Services to the Public Switched Telephone Network (PSTN). A certified Session Border Controller (SBC) sits between your existing carrier and Microsoft Azure, routing calls securely into the cloud.

TECHOM Systems operates a live, TLS-secured SBC at ACS01.TECHOMSYSTEMS.COM.AU on port 5112. As shown in the Azure portal screenshot below, this endpoint is Online with Active TLS status, ready to handle production call volumes today.

This architecture allows organisations to adopt cloud-native telephony without abandoning existing carrier relationships, geographic numbers, or 1300/1800 helpline numbers. It is the migration path that eliminates disruption while accelerating digital transformation.

2. The Dynamics 365 Voice Channel: Contact Centre Inside Your CRM

The Dynamics 365 Voice Channel is a native contact centre capability built directly inside Microsoft Dynamics 365 Customer Service. It is not a third-party integration. Microsoft owns the entire stack, which means updates are coordinated, features are designed to work together, and integration risk is eliminated.

When Azure Communication Services with Direct Routing powers the Dynamics 365 Voice Channel, agents receive and make calls without leaving their CRM environment. When an inbound call arrives, the customer's record opens automatically. No screen-popping to a separate softphone. No manual call logging.

What the Voice Channel Delivers for Agents and Supervisors

• Embedded softphone inside Dynamics 365, no separate telephony client required
• Automatic screen pop with full customer history, open cases, and recent interactions on every inbound call
• Outbound calling placed directly from contact records and case pages
• IVR flows and intelligent call routing built and managed inside Dynamics 365
• Real-time transcription of every call using Azure AI services
• Post-call sentiment analysis and structured conversation summaries
• Supervisor dashboards with live call monitoring, barge-in, and whisper-coaching
• Microsoft Copilot suggestions for knowledge articles and next-best actions during live calls

3. Business Benefits That Drive Commercial Value

Eliminate Infrastructure Costs

Legacy contact centres require physical PBX servers, ISDN lines, on-premise infrastructure, and specialist telephony engineers. Maintenance contracts alone consume significant IT budget year after year.

Azure Communication Services Direct Routing eliminates most of this overhead. TECHOM Systems provides the SBC connectivity layer. Microsoft manages the cloud infrastructure. For a 50-seat contact centre, infrastructure savings over three years typically exceed $80,000–$150,000 AUD, depending on the age and complexity of existing systems.

Retain Existing Numbers and Carrier Contracts

Direct Routing allows organisations to keep every phone number — geographic numbers, 1300 and 1800 numbers, DDIs, and their existing carrier agreements. Numbers port across during migration. There is no service interruption and no change to customer-facing contact details.

Support Hybrid and Remote Teams Globally

The Dynamics 365 Voice Channel operates entirely in a modern web browser. Agents work from any location with an internet connection. Supervisors monitor live calls, barge in, and whisper-coach in real time, regardless of where those agents are based.

This is a significant operational advantage for organisations with distributed teams across multiple time zones, including businesses with contact centres in Australia, the UK, the US, or offshore locations.

Unify Communication and CRM Data

Every call handled inside Dynamics 365 is automatically logged, transcribed, and associated with the correct customer record. No manual notes. No missed interactions. Sales teams review call recordings before follow-ups. Support teams see every previous case and resolution in one place. The data silos that separate telephony from CRM are permanently closed.

4. AI and Call Intelligence Capabilities

Azure Communication Services and Dynamics 365 are deeply integrated with Microsoft's AI platform. These capabilities are included within the Voice Channel — not separately licensed add-ons.

Real-Time Transcription and Searchable Call Records

Every call through the Dynamics 365 Voice Channel is transcribed in real time. Agents and supervisors see the transcript live on-screen. After the call, the full transcript is stored against the customer record and is fully searchable. Compliance teams can query conversation content without listening to recordings.

Sentiment Analysis and Proactive Escalation

Azure AI monitors the emotional tone of both the agent and the customer throughout the call. Real-time sentiment indicators appear on the supervisor dashboard. If customer sentiment turns negative, supervisors are alerted immediately. Proactive intervention reduces escalations and improves customer retention.

Microsoft Copilot for Agent Assistance

Microsoft Copilot is integrated into the Dynamics 365 Voice Channel. During a live call, Copilot surfaces relevant knowledge articles, similar resolved cases, and product information in real time. New agents become productive faster. Experienced agents handle more complex queries with greater confidence. Average onboarding time reduces significantly.

Post-Call AI Summaries and Action Capture

After each call, AI generates a structured summary of what was discussed, what actions were agreed, and what follow-up is required. This summary is automatically attached to the customer record. Agents do not write manual notes. Managers receive accurate, structured reporting across every agent and every interaction automatically.

5. Global Use Cases by Industry

Financial Services and Insurance

Financial services organisations use Azure Communication Services Direct Routing for compliance call recording, real-time transcription for audit trails, and intelligent routing to specialist advisers. Copilot assists agents with product information during live calls, while IVR menus reduce queue times and improve the customer experience from first contact.

Healthcare and Allied Health

Healthcare providers manage appointment bookings and clinical queries with patient records surfacing automatically during inbound calls. Role-based access controls restrict sensitive data to authorised staff. Call recording retention policies are configured to meet clinical governance and regulatory requirements across different jurisdictions.

Professional Services

Law firms, accounting practices, and consulting organisations log calls against client matter records, trigger time entries from call outcome data, and give every team member complete client interaction history before callbacks. Call recordings stored in Dynamics 365 become a permanent part of the client file.

Retail, E-Commerce, and Government

Retailers resolve delivery queries faster when order history appears automatically on-screen. Government agencies retain 1300 and 1800 helpline numbers via Direct Routing while meeting data sovereignty requirements through Azure's regional data centres. In every sector, the common outcome is fewer systems, faster resolution, and richer customer data.

6. Implementation Considerations

A TECHOM Systems deployment follows five structured phases: Discovery and Assessment, Infrastructure Configuration, Voice Channel Deployment, Training and Go-Live, and Ongoing Optimisation. Most organisations are fully operational within two to six weeks of engagement start.

• Licensing: Azure subscription, ACS resource, and Dynamics 365 Customer Service with Voice Channel add-on
• Network readiness assessed before deployment; QoS policies prioritise voice traffic for consistent call quality
• Number porting and carrier coordination managed entirely by TECHOM Systems throughout migration
• Security: TLS encryption on all call signalling via TECHOM SBC; Azure encrypts call media in transit
• Data residency available across Azure Australia, Azure UK, Azure US East/West, and Azure EU regions
• Agent training typically achieves full productivity within one day of go-live
