Call
centers have evolved greatly in recent years with the advent of VoIP
telephony and PBX IP PBX solutions based on open source software.
Currently there are several types of telephone switchboards, as conventional PBXs that are connected to the PSTN, the IP PBX to work with data networks over IP using VoIP technology and can interact with the PSTN hybrid PBXs and VoIP support Centrex PBX.
Classes of telephone
The PBX telephone exchanges or have been transformed in recent years, moving from analog to digital half, then finally to digital and IP PBXs that work internally over IP, provided a breakthrough in CTI ( Computer Telephony Integration, Computer Telephony Integration).
We can distinguish various types of telephone:
PBX (Private Branch Exchange Private Branch switching) PBXs are the conventional telephone exchanges enabling direct access to the public telephone network PSTN (Public Switched Telephone Network), also called PSTN (Public Switched Telephone Network) lines through trunks. This type of PBX is run autonomously both internal and external calls (incoming and outgoing), and usually usually belongs to the company that has installed and not the telephone operator.
IP PBX (also called VoIP PBX, IP PBX or VoIP PBX) telephone exchange PBX IP PBX is designed to work with data networks over IP, using VoIP (Voice over IP, Voice over IP) via the Internet. They can interact with the conventional telephone network PSTN, both analog PSTN (Basic Telephone Network) and digital ISDN (Integrated Services Digital Network) and GSM / GPRS / UMTS. Also, you can connect standard telephones (analog phones, fax or DECT cordless phones) using a VoIP gateway or ATA (Analog Telephone Adapter). The IP PBX PBX equipment can be a physical hardware or a software system, called Soft IP PBX.
VoIP PBX support (also called hybrid PBX) is a module connected to a PBX VoIP standard, thus allowing the PBX provides the functionality of an IP PBX and can operate both through the PSTN and through data network via VoIP.
Centrex PBX (also called PBX or Hosted Virtual PBX) service PBX emulation, called Centrex (Central Exchange, Clearing House) is a service provided by telephone companies is that the customer has all the functions a PBX phone system through a simulation carried out by the public telephone exchange zone, configured such that the lines come to appear to function as a client telephone exchange PBX. You can virtualize both a conventional PBX and IP PBX, being called in this case Virtual Hosted IP PBX or IP PBX.
