In the new era of Work from Anywhere, migrating to a cloud-based phone system like Microsoft Teams Phone delivers the flexibility, scalability, and functionality you need to support a modern business environment without heavy infrastructure investment. But telephony Microsoft Teams phone migration isn’t turnkey for companies with global footprints that stretch outside Microsoft’s coverage area – and several key considerations are essential to ensuring a smooth experience when a third-party telecom vendor is required.

As organizations adopt flexible work models, the need for 24/7 mobility has a growing number cutting the cord with the traditional concept of a fixed phone on a fixed desk in a fixed office.

Microsoft’s cloud-based voice calling capability keeps communication flowing smoothly no matter where employees are – giving remote workers access to a full-featured phone system while ensuring customers receive a consistent calling experience. Calls can be answered from multiple devices, including computers, mobile devices, and Teams-enabled desk phones.

As an add-on to Microsoft 365, Teams Phone also helps companies keep external and internal communication activities like chat, messaging, video calls, phone calls, and collaboration in a single place – boosting efficiency, tracking, and productivity. It seamlessly integrates with other Microsoft 365 products as well like SharePoint and Outlook, enabling users to quickly access content without leaving the interface.

Microsoft reports more than 80 million active Teams Phone users placing more than a billion calls monthly. More than 90% of the Fortune 500 has used Teams phone capabilities.

Such high demand is underscored by the rapid growth of the overall global cloud telephony services market, which is projected to expand nearly 17% this year to $20.7 billion.

But leaping into a cloud-based phone system without taking time to understand the complexities of global implementation sets you up for trouble down the road. Microsoft calling plans don’t cover all geographies – and finding the right third-party provider to fill the gaps can be challenging.

Here are 4 smart tips for global enterprises considering adding Phone services to their Microsoft Teams Phone migration:

How to prepare for a smooth Microsoft Teams Phone migration with third-party vendors

1. Assess your global footprint and services.

Ensuring a smooth transition from a legacy phone system to Teams Phone requires a clear understanding of your global needs.

Profile your users, digging into the details of existing locations and services so they can be mapped to your new solution. Be sure to also consider regional specifics like regulatory measures that you need to comply with at each location.

2. Determine if Microsoft offers service at all your locations.

Microsoft currently offers calling plans in about 30 countries. For businesses with offices in countries that can use some Teams Phone services but are unable to obtain Microsoft phone numbers, Microsoft relies on third-party partners like AT&T, Verizon, BICS, Intrado, and more that can integrate their services with Teams Phone.
