Types of PBX
- The IP centrex
This is an external switchboard , with an IPBX installation, but hosted by an operator that shares its telephone infrastructure, in cloud mode , among several clients.
Since the switchboard is external, the company brazil whatsapp shopping data that implements it only needs to purchase IP telephony stations .
It is for security reasons (regarding the data hosted on these shared servers) that certain solutions using the Centrex system are evolving towards dedicated SaaS ( Software as a Service , in the cloud) platforms . Skype is one of them.
Centrex IP is suitable for small and medium-sized organisations (SMEs) as the number of connected workstations is limited to around twenty.
- The virtualized IPBX (or Virtual PBX for Virtual Protocol Branch eXchange )
The alternative to the private switchboard or PBX is known as Internet telephony or VoIP .
Also known as IP telephony or hosted telephony, it is a solution hosted on a server by a specialized operator, which passes through a router and the Internet.
This is a private external PBX , 100% in the cloud, a mix between IPBX (hosting on a dedicated server) and the Centrex platform (without telephone infrastructure to manage). It is said to be more secure than IP Centrex, which directs all communications through a single location.

instant messaging,
