Enterprise Communications Experts for Microsoft Teams

Our Background

We’re a division of Altigen Communications dedicated to delivering integrated solutions for Microsoft Teams Phone System.  For nearly two decades Altigen has been helping organizations around the world improve their business communications and lower their total cost of ownership.  We created Voice for Teams to deliver those same benefits to customers and partners for their Microsoft Teams Phone System deployments.

Our Expertise

More than just a buzzword, when it comes to Microsoft Unified Communications solutions our expertise runs deep.  From the start we’ve been developing PBX and Contact Center applications based on the Microsoft stack. We were also one of the first companies to  introduce an integrated Contact Center solution for OCS 2007, and have continued to enhance and extend those capabilities for Microsoft Lync, Skype for Business and, now, Teams Phone System.   Today, as a Microsoft Cloud Communications Provider, we also offer hosted Skype for Business, hosted Contact Center and integrated SIP trunks (Direct Routing) for Teams.

If you’re looking for a business partner possessing the skills and experience to successfully deploy, support and enhance the value of Microsoft Teams Phone System, we’ve got you covered.
