Cloud PBX is an enterprise-class phone system you can implement without a huge up-front cost. It replaces traditional phone systems using a SaaS model to deliver calling features of Microsoft Office 365 with Skype for Business Online. Cloud PBX enables you to complete basic tasks such as
making and receiving calls; transferring calls; and muting or unmuting calls, from in the office, at home, or on the road, using your phone, PC, or mobile device. The Skype for Business Cloud PBX
gives you PBX capabilities, but without the complicated and expensive equipment.
