What is PBX?

PBX allows your callers to reach your employees on one single number using extensions.

Your employees can also speak with one another directly without incurring other costs. However, with the advent of VoIP, Instant Messging (IM), PC voice chats and inexpensive mobile rates, the communication between employees is often direct.

Virtual PBX Background (Hosting)

Before the dotcom, servers for services such as email, web and database servers were hosted internally.

The companies have realized the cost benefits and started outsourcing the hosting of these servers. Third party hosting providers guaranteed backup, redundancy and uptimes.

Virtual PBX is similar trend to hosting in telecom space. Hence, it is often referred as Hosted PBX.

Since the hosting providers often use cloud computing (scalable hosting), Hosted or Virtual PBX terminology is now being replaced with cloud PBX.
