- Microsoft Teams telephony
Your team already uses Microsoft Teams to communicate and collaborate. Why manage business phone calls through a completely separate system?
With Microsoft Teams telephony, you can connect your business phone service to your Microsoft 365 environment, allowing employees to make and receive external calls directly through Teams.
IconicKloud helps businesses integrate Microsoft Teams with Public Switched Telephone Network (PSTN) services, configure business calling and explore options for transferring existing phone numbers. The result is a more connected communication environment that brings everyday collaboration and business telephony together.
Make business calls directly from Microsoft Teams
Turn Microsoft Teams into a central communication platform for your organisation. With the right Microsoft Teams Phone configuration and PSTN connectivity, employees can make and receive calls to external landlines and mobile numbers through the Teams application.
Instead of switching between separate communication tools, your team can manage internal collaboration and business calls from one familiar workspace.

Our Microsoft Teams telephony services
From PSTN connectivity to business number migration, we help configure Microsoft Teams calling around your organisation’s communication requirements.
Microsoft Teams Phone integration
Connect Microsoft Teams with business telephony services to enable external calling. We help configure the required phone system components and connectivity so users can manage business calls within Teams.
PSTN connectivity and integration
Connect your Microsoft Teams tenant to the Public Switched Telephone Network (PSTN), allowing authorised users to make and receive calls beyond your organisation. Depending on your requirements, connectivity options may include Direct Routing, Operator Connect or an available Microsoft Calling Plan.
Business phone number porting
Keep your existing business identity when moving to Microsoft Teams telephony. We help assess number porting requirements and coordinate the process of transferring eligible existing numbers to a supported Teams calling arrangement. Number availability and transfer conditions depend on your current carrier, location and selected PSTN provider.
Inbound and outbound calling
Enable employees to handle incoming and outgoing business calls through Microsoft Teams. This allows users to communicate with customers, suppliers and other external contacts using their assigned business numbers.
Teams calling configuration
Configure relevant voice settings, user assignments and calling policies to support your organisation's telephony requirements. The setup can be tailored to your users, locations and selected PSTN connectivity model.
Business telephony modernisation
Move towards a cloud-based business phone system by bringing telephony into your Microsoft Teams environment. This can help reduce the need to maintain separate communication platforms and simplify everyday calling.
How Microsoft Teams connects to PSTN
Microsoft Teams Phone provides the calling functionality, while a PSTN connectivity service enables calls to external telephone numbers. Depending on your business requirements, there are different ways to establish this connection.
Direct Routing
Connect your existing telecommunications provider to Microsoft Teams through a supported Session Border Controller (SBC). This option can suit businesses that want to retain their preferred carrier or require specific telephony integrations.
Operator Connect
Connect Teams Phone to a participating telecommunications provider through Microsoft's Operator Connect programme. The participating operator manages the PSTN connectivity, while your organisation manages relevant users and numbers through Teams administration.
Microsoft Calling Plans
Use Microsoft's cloud-based calling service where available. Microsoft provides the PSTN connectivity, subject to regional availability, licensing and service requirements. The appropriate option depends on your existing phone services, number requirements, locations and preferred level of telephony management.
Why move your business phone system to Microsoft Teams?
Traditional business phone systems can involve separate infrastructure, administration and communication tools. Microsoft Teams telephony offers an alternative by bringing external calling into an environment employees may already use every day.
One familiar communication platform
Bring business calls and team collaboration together in Microsoft Teams. Employees can use the same application for chats, meetings and supported external calling.
Greater workplace flexibility
Support employees working from the office, remotely or across multiple locations. Users can access Teams calling through supported desktop and mobile applications, subject to their configuration.
Keep your existing business number
Where number porting is supported, your organisation can explore transferring eligible existing telephone numbers rather than automatically starting with new numbers.
Simplified telephony administration
Manage relevant users, numbers and calling configurations through the Microsoft Teams administration environment, depending on your selected PSTN connectivity model.
A cloud-based calling environment
Reduce dependence on traditional on-premises phone infrastructure where a suitable Teams Phone deployment can meet your communication needs.
