Customer Scenario – Altigen Direct Routing

The Wonder Widget Company, headquartered in North America with offices in the UK and Europe, had on premises PBX systems from multiple manufacturers. Their goal was to eliminate the expense of those disparate PBX systems and consolidate all employees onto a single cloud communications platform.

As a Microsoft 365 customer, Teams Phone System was the clear choice due to it's integration to Microsoft 365 and simplified user management compared to the other hosted PBX providers.

WWC selected Altigen to provide Direct Routing SIP trunks services for the majority of WWC's locations, while leveraging Microsoft Calling Plans in branch offices having less than 5 employees.

Altigen was further chosen to deploy and support the entire solution due to our ability to set up WWC's 1,000 employees on Teams Phone System, and deploy both Altigen Direct Routing and Microsoft Calling Plans. Not only was the project successfully completed on time, WWC also saved more than 50% with Altigen Direct Routing versus Calling Plans.
