What is the difference between traditional PABX and VOIP?

Using VoIP instead of PABX within a private network can offer many advantages : 

- Sound quality is better- We can also make video communication (if this feature is supported by the deployed IP Phone) - We can make some economy if we replace basic PSTN Phone by SoftPhone that< can be installed on the Desktops, on Laptops or even on the different Mobile Phones of the employeers of the company- We can easely configure more value added services  (ring all, transfer call, send voice mail message, etc..) - People outside the compagny can user Internet to make call or to receive calls using their Smartphone (by installing a Softphone)- People  who  travel outside their country can use  their VoIP Gateway (IPBC) to make Internet call using the PSTN Number of their compagny.

he acronym PBX stands for Private Branch eXchange. In legacy telephone systems, the term PBX was used to distinguish private business systems from common carrier or public telephone systems. Early PBX systems used operators to manually connect incoming and outgoing calls. Today, any private telephone system with multiple lines can be called a PBX system.

Traditional PBX systems were only compatible with the Public Switched Telephone Network (PSTN). In the current business telephone market, many PBX systems are compatible with both PSTN and Voice over IP (VoIP) technology. These are sometimes referred to as hybrid systems, and they have the advantage of managing calls for either PSTN or VoIP telephones.

There are features that VoIP systems offer that are not available in other technologies. Voicemail and fax integration with email are examples of VoIP only features that are becoming standard business features. The ability to receive voicemails and faxes through email can greatly improve productivity and responsiveness for any business. VoIP systems can also include mobile and text messaging capabilities that are not part of the standard PBX feature set.

VoIP systems are more flexible also. Adding lines and users involves making a few changes in a web-based interface, while in a PBX system these may require hardware and software updates. VoIP systems are designed to be scalable and do not require hardware upgrades to add lines or users.
