VOIP PBX

PABX - PBX

The telephone, or in technical jargon PBX or PABX (Private Automatic Branch eXchange acronym) is a device used on farms to provide internal telephone system. Basically the two basic features of a PBX are:

make the connection between two telephone terminals uniquely identified through internal numbering;
allow the so-called DDI, or allow incoming calls from the public can reach one or more telephone terminals of the telephone network company.

Besides these basic functions, a PBX can provide many other functions, such as:

Automatic Call Distribution (ACD);
Intercom, ability to interconnect to the intercom system for access control and door opening;
Computer Telephony Integration (CTI)
Interactive Voice Response (IVR)
Documentation of telephone traffic
Music on hold
Day / night variation of the input mode for external calls on the base of
Recording of conversations
Least Cost Routing can route outgoing traffic on various operators / lines

This list is not exhaustive and there are many other functions and services implemented with a PBX

Configurations, the telephone systems are interfaced to the public telephone line connections via analog or digital (ISDN) and can handle a variable number of lines to over a hundred.

VoIP PBX

The VoIP PBX is a natural evolution of the traditional switchboard. The spread of LANs in the enterprise and the increasing availability of broadband Internet has made possible the transmission of telephone traffic over IP networks: VoIP is in fact an acronym for Voice over Internet Protocol, Voice over IP and then.

Voice transmission on a normal network connection opens a huge range of possibilities that do not mean only substantial cost savings on utility bills, but also solutions to problems that once were not easily resolved or were not affordable: think of the connection two locations of a company in two locations in different countries.

If we want to know the benefits from adopting a VoIP PBX, we list some:

Wiring costs reduced because all the telephone traffic travels on the cable network. In fact, most VoIP devices have a socket "pass" that lets you share the same network connection on your PC.
The phone system is easily expandable, since - unlike the traditional PBX, where it was necessary to purchase additional dedicated hardware - simply buy new handsets and connect to the data network.
Immediate availability of all the telephone services that are optional in the traditional PABX and payment.
