We live in a computer age and we no longer do things the traditional way. Business – regardless of the size and scale of its operations – is becoming increasingly dependent on the Internet for day-to-day operations. As we know, PBX (Private Branch Exchange) makes connections between internal telephone of private organizations and also connects to PSTN (Public Switched Telephone Network) through trunk lines.
They not only facilitate telephone communication but also fax and modem sending for all other voice/data transmissions. Businesses of all sizes can benefit from cloud PBX VoIP in Australia via smartcombusiness.com/hosted-cloud-pbx Initially, the main advantage of PBX was the cost savings on internal telephone calls.
When PBX became more popular, they began offering services that were not available on the operator's network, such as group hunting, call forwarding, and extension calls. Two important developments occurred during the 1990s that led to new types of PBX systems. Users need packet-switched networks for data, so using them for phone calls is a natural thing.
The availability of the Internet as a global delivery system makes packet-switched communication easier. These factors lead to the development of VoIP (Voice over Internet Protocol) PBX. VoIP, also known as IP Telephony, is the transmission of voice signals in real-time using Internet Protocol (IP) over the public Internet or private data networks.
Then there is the realization that PBX services are always difficult and expensive for small businesses, and many small and medium-sized businesses understand that handling their own telephone is beyond their core competence.
