Phone System in Office 365
Simplify your business with a reliable, cloud-based telephone solution. Phone System in Office 365 provides the features you need to eliminate traditional PBX systems and the associated costs.
Common calling features
Transfer, hold, and resume calls with a single touch. Let your assistant receive calls on your behalf. Answer calls for other people on your team when they’re unavailable.
Voice mail
Take advantage of built-in voice mail, integrated with Exchange, to quickly respond to missed calls.
Encryption by default
Protect your privacy and your intellectual property with built-in encryption, enabled by default. No VPN needed.
Flexible Calling Plans
Simplify your systems
Calling Plans bring the benefits of the cloud to your phone system by shifting your phone needs to Office 365.
Elevate your services
Because Calling Plans are a part of Office 365, it enables services, security, and support that traditional phone lines can’t match.
Connect your business
With Calling Plan, 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 Phone System in Office 365. This allows customers to use Phone System worldwide with calling services provided by the telco operator of their choice instead of using Calling Plan.
Investment protection
Use existing telephone lines, phone numbers, and Calling Plans with Phone System.
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 Phone System while still taking advantage of your existing telephone lines and services.
Person-to-person calling
Skype for Business provides voice-over-IP (VoIP) calling over your network and the Internet to users in your company, Skype for Business users in other companies, and Skype consumer users around the world. Users can easily add video or content sharing to any call.
Dial by name, from Office
Reach people easily, when you need them, with a single touch or click from your contact list in Skype for Business, or the contact card in any Office application.
Skype connectivity
Connect, communicate, and collaborate with colleagues, consumers, other businesses, and friends and family—anyone who uses Skype—with both voice and HD video.
Anywhere access
Make and receive business calls in the office, at home, or on the road, using your business number on your smartphone, tablet, PC, or desk phone. With Office 365, your calls come to you.
