The Analog PBX manages calls between phones and fax machines by being physically connected to them over copper wiring. Incoming calls are routed through the PBX and out to the phones, and calls can be transferred between phones via the PBX. The PBX itself typically lives in an office's telecom closet.

The key to an analog PBX is that it connects to POTS lines that pre-date the Internet. These systems are not capable of many modern-day phone system features, such as voicemail-to-email, and they cannot deliver high definition voice calls.

Digital PBXs offer a number of advanced features while providing the same (or better) voice quality and improved signal processing than analog PBXs. Some of these features include call forwarding, voicemail and virtual auto attendants. They provide the flexibility of adding new features and capabilities by adding new cards (add-on modules) on the bus structure in the existing PBX cabinet, such as:

1.RFID Attendance System

2.Additional features like VoIP server, alarm systems and music-on-hold can be added.

3.Call center and enterprise sales software can be integrated.

With the gradual replacement of copper lines with broadband Internet, Internet Protocol IP PBX are the most common systems used in enterprises. An IP PBX delivers voice calls over the Internet, otherwise known as VoIP. A premise-based IP PBX is a VoIP-based phone system that is housed within the office, also typically in a telecom closet. Instead of physically connecting to the PBX with copper wiring, phones connect to the PBX over an office's Local Area Network (LAN), often leveraging the same Internet connectivity of your office.

Because they leverage the Internet, IP PBXs are capable of high definition audio and many other sophisticated PBX features, such as call queuing, flexible business hour rules, and application integration, interchanging with other unified communications and CRM platforms.

A hybrid PBX combines existing analog PBX equipment with VoIP. A PBX connects internal users to the outside world with a PRI or BRI, which has 24 channels. There are often many PRIs to connect hundreds of phones. In a hybrid PBX system, these PRIs connect to Hybrid PBX device and the two devices connect to the outside world via both PSTN trunks and SIP credentials. The hybrid PBX also has many IP extensions to connect directly to IP phones in the office.

A hybrid PBX has many of the same great features you can expect from VoIP services, including call rules, auto-attendant, and hold queues. The hybrid PBX also has the capacity for virtual conference rooms, fax over IP, and videoconferences. The hybrid PBX also can do SIP trunking. The most important feature of the hybrid PBX is that if either the analog PBX or the VoIP server isn’t working, it automatically switches over to the other network.

One of the biggest benefits to having a hybrid PBX is for remote offices and secondary locations. Calls from one office to the other go through the hybrid PBX, so there are no long-distance charges. If a location is temporary, such as an amusement park or construction site, you can use cordless phones to connect directly to the hybrid PBX instead of going through the building’s telephone lines.

Interactive Voice Response (IVR) is an automated telephony system that interacts with callers, gathers information and routes calls to the appropriate recipient. An IVR system (IVRS) accepts a combination of voice telephone input and touch-tone keypad selection and provides appropriate responses in the form of voice, fax, call-back, e-mail and perhaps other media.

IVR systems can respond with pre-recorded or dynamically generated audio to further direct users on how to proceed. IVR systems deployed in the network are sized to handle large call volumes and also used for outbound calling, as IVR systems are more intelligent than many predictive dialler systems.
