Cloud Telephony and Microsoft Teams Voice
Cloud telephony and Microsoft Teams integration: how it works
Learn how Intuity helps organisations move from legacy phone systems to cloud telephony, Microsoft Teams voice, Operator Connect or Direct Routing with a practical deployment plan that protects users, numbers, call flows and customer experience.
Quick answer
Cloud telephony and Teams voice integration connects business calling, users, numbers, routing, voicemail and collaboration into a modern communication platform. Intuity reviews your current PBX, Microsoft licensing, connectivity, devices and call flows before recommending the best route, such as cloud telephony, Microsoft Calling Plans, Operator Connect or Direct Routing.
Problem
Why businesses review cloud telephony and Teams voice
Many businesses use Microsoft Teams every day for meetings and chat, while external calling still sits on a separate phone system. This can leave users switching between tools, remote workers relying on mobiles, and managers struggling to see call performance clearly.
A move to cloud telephony or Teams voice can reduce legacy system reliance, simplify user experience, improve hybrid working and make communications easier to manage. The key is choosing the right design for the organisation, not simply moving every user to the same product.
Typical triggers
- Ageing PBX or end-of-life phone system
- Hybrid workers need consistent calling
- Microsoft Teams is already widely adopted
- Call routing and reporting need improvement
- Existing SIP, ISDN replacement or number migration project

Scenario
Hybrid workforce with Teams voice
A 250-user organisation has two offices, home workers and mobile sales users. Teams is already used for meetings, but external calling remains on a legacy PBX. Intuity reviews the PBX, DDIs, call flows, Teams licences, headsets, handsets, connectivity and support requirements.
A pilot group tests Teams calling, voicemail, transfer, mobile access and call queues. Reception and customer service users are assessed separately because they may need more advanced handling. After testing, users are migrated in phases and call data is reviewed after go-live to improve routing.
Scenario
PBX migration without a risky cutover
A business with an established PBX wants cloud voice but cannot risk a single overnight change. Intuity maps extensions, hunt groups, DDIs, analogue lines, alarms, lift lines, reception flows and out-of-hours rules.
A staged migration can keep some legacy services in place while selected departments move first. This gives the business time to validate real-world calling before the old platform is retired.
Compare
Which Teams voice route fits best?
Microsoft Calling Plans
Best for simpler requirements where Microsoft-provided calling is commercially and operationally suitable.
Operator Connect
Good for organisations that want carrier-managed Teams connectivity with simpler administration.
Direct Routing
Useful where the organisation needs SBC control, complex routing, SIP integration, staged migration or contact centre alignment.
Cloud telephony alongside Teams
Suitable where Teams is important but some users need dedicated UC, reception, handset or contact centre capability.
FAQs
Questions about cloud telephony and Teams integration
Can we keep our existing numbers?
Usually yes, subject to provider checks and number porting requirements. Intuity reviews the number estate before planning migration.
Do all users need new handsets?
No. Many users can work with headsets and softphones. Reception, meeting room and specialist users may still need physical devices.
Is Direct Routing better than Operator Connect?
It depends on routing, resilience, supplier preference, contact centre needs and migration complexity. Intuity can compare both routes.
Can Teams replace a PBX completely?
For many organisations it can, but analogue services, reception workflows, contact centre features and complex routing should be reviewed first.
Planning cloud telephony or Microsoft Teams voice?
Intuity can review your current setup, compare the available routes and help you plan a practical migration.
