Understanding Asterisk The primary advantage of PBXs was cost savings on internal phone calls. How?

Understanding Asterisk

The primary advantage of PBXs was cost savings on internal phone calls.

How?

Understanding Asterisk By handling the circuit switching locally. Compare the cost of 3 phones connected directly to a COX , and between 3phones connected to a PBX.

The First reason :

The massive growth of data networks.

The Second reason :

The understanding of packet switching.

Understanding Asterisk we can use packets in switching data . And we can use them in holding voice also. Since Internet is a global delivery system , so it's easy.

Understanding Asterisk VoIP PBX supports VoIP besides PSTN . It can connect IP phone to PSTN phone , and vice versa. So,it's linked to both the VoIP provider and the PSTN Provider.
