Connecting Microsoft Office 365 Teams users to an existing company phone system (PBX)

Combining Teams functionality with your existing PBX system

Microsoft Teams is the Office 365 team hub created to enhance team working, bringing calling, chat, and meetings, along with workplace collaboration features, into one platform.

Phone system functionality is available via:

Microsoft 365 Business Voice: Business plans (for SMBS, organisations with up to 300 users) as a with and a without calling plan
Microsoft 365 Enterprise Voice: Enterprise plans (for 300+ user businesses), incorporated into the E5 plan, and as an add-on for the E3 plan – both versions without calling functionality.
Call2Teams enables businesses to utilise their existing PBS systems, in conjunction with Call2Teams’s calling plans.
