A PBX, also known as a Cloud PBX or Virtual PBX, is a cloud-based Private Branch Exchange system which is accessed through an IP network.

Hosted PBX's are managed completely off-site, cutting out the large investment and ongoing maintenance. Instead of having a phone equipment room and knowledgeable staff, business owners are able to manage their phone system through an easy-to-use portal. Leaving the complexities of a traditional PBX system behind.

• Service Providers can easily offer a Virtual PBX solution to far more markets and verticals than traditional PBX systems could ever reach.
• Because of its extreme affordability, a Hosted PBX solution is a lot easier for Small to Medium Businesses to adopt. Which makes selling UC that much easier for the Service Providers.
