Simplify your systems

PSTN Calling brings the benefits of the cloud to your phone system by shifting your phone infrastructure to Office 365.

Elevate your services

Because PSTN Calling is part of Office 365, it enables services, security, and support that traditional phone lines can’t match.

Connect your business

With PSTN Calling, you can unify your communications services in Office 365 and integrate calling with your business processes to increase productivity.

Cloud connectivity

Cloud Connectivity uses software on premises to connect existing telephone lines to Cloud PBX in Office 365. This allows customers to use Cloud PBX worldwide with calling services provided by the telco operator of their choice instead of using Microsoft PSTN calling.

Investment protection

Use existing telephone lines, phone numbers, and calling plans with Cloud PBX.

Deployment flexibility

All versions of Skype for Business Server software include cloud connectivity. Use an existing Skype for Business Server installation if available, or setup a new, small footprint deployment. Migrate some or all of your users to Cloud PBX while still taking advantage of your existing telephone lines and services.
