Microsoft Teams Phone

Microsoft Teams Phone

The Microsoft Teams Phone System is a unified communication solution that seamlessly integrates with the Microsoft Teams platform. It empowers organisations to make and receive calls, host audio and video conferences, and send messages all within the Teams interface.

Teams Phone leverages VoIP technology, enabling users to transform their devices into full-fledged phones, complete with features like call routing, voicemail, and call forwarding. It also supports traditional PSTN (Public Switched Telephone Network) connectivity, ensuring compatibility with external phone lines.

Microsoft Teams Phone System fosters efficient collaboration by uniting voice, video, and messaging, making it an invaluable tool for modern businesses striving for productivity and connectivity.

Microsoft Calling Plans vs. Direct Routing

Microsoft Calling Plans and Direct Routing are two different approaches for enabling telephony services in Microsoft Teams. They offer distinct features and flexibility, and the choice between them depends on your organisation’s specific needs and requirements.

Here are the key differences between Microsoft Calling Plans and Direct Routing:

Service Provider

    • Microsoft Calling Plans: With Calling Plans, Microsoft acts as the service provider for your phone system. You purchase phone numbers and calling services directly from Microsoft.
    • Direct Routing: Direct Routing allows you to connect Microsoft Teams to your own telecommunications provider (like Marlin Communications), which can be a third-party VoIP provider or a Session Border Controller (SBC) managed by your organisation.

Phone Numbers

    • Microsoft Calling Plans: You can acquire phone numbers directly from Microsoft, and they are available in select countries and regions. Microsoft manages the provisioning and porting of these numbers.
    • Direct Routing: You can use your existing phone numbers or acquire them from your chosen telecommunications provider. You have more flexibility in selecting and managing your phone numbers.


    • Microsoft Calling Plans: Microsoft charges per user, per month, for calling plans. The pricing typically includes a bundle of minutes for domestic and international calling.
    • Direct Routing: Costs can vary depending on your chosen telecommunications provider and their pricing structure may provide more cost flexibility, especially for organisations with high call volumes or specific international calling needs. Direct Routing from Marlin Communications can reduce your calling costs by up to 50%. 

International Calling

    • Microsoft Calling Plans: International calling may be included in the plan or available as an add-on. Microsoft offers international calling rates and plans for various countries.
    • Direct Routing: You can choose your own telecommunications provider for international calling, potentially providing more options for competitive rates.

Hardware and Infrastructure

    • Microsoft Calling Plans: Requires no additional on-premises equipment. All the phone system services are hosted in the Microsoft cloud.
    • Direct Routing: Requires an SBC (Session Border Controller) to connect your existing telephony infrastructure to Microsoft Teams. This can be either on-premises or cloud-based.


    • Microsoft Calling Plans: Easier to set up and manage, but may have limitations in terms of number availability and pricing flexibility.
    • Direct Routing: Offers more flexibility and control, especially for organisations with complex telephony needs or specific regulatory requirements.

Regulatory Compliance

    • Microsoft Calling Plans: May be subject to certain regulatory limitations and requirements depending on the region. Compliance is managed by Microsoft.
    • Direct Routing: Provides more control over regulatory compliance as you can choose your telecommunications provider and SBC, ensuring they meet specific compliance requirements.
