With Skype for Business, Microsoft gives you three compelling solutions for your voice needs:
- Enterprise Voice (on-premises): Included in on-premises deployments of Skype for Business Server 2015, this is Microsoft's world-class software-powered Voice over Internet Protocol (VoIP) solution. It's a full PBX system that uses PSTN connectivity through your local operator.
- Cloud PBX with PSTN Calling service (all in the cloud): Included with Skype for Business Online, Cloud PBX is Microsoft's new technology for enabling call control and PBX capabilities in the Office 365 cloud. Skype for Business Cloud PBX allows you to replace your existing PBX system with a set of features directly delivered from Office 365 and tightly integrated into your cloud productivity experience.
- Cloud PBX with On-premises PSTN connectivity (a choice of hybrid solutions): You can choose Cloud PBX with an existing Skype for Business Server deployment or Skype for Business Cloud Connector Edition (currently in Preview).
