HOW DOES PBX WORKS ?

A PBX (Private Branch eXchange) is a phone system switch that can connect many internal telephone lines to a few external PS TN lines. With a PBX all of the in house phones connect using designated extension, usually just a few digits - it can also connect any extension with an outside line and any outside caller can make a direct call to any extension using a set prefix followed by the extensionnumber. This function and other capabilities like answering service, call transferring and collecting of call statistics is handled by integrated software.

Benefits of VoIP PBX
A VoIP PBX is different than a traditional PBX in the sense that your telephone calls are transmitted via your IP network, hence the name IP PBX (or VoIP PBX). An IP PBX doesn’t mean you have to give up your existing analog lines either; there is a difference between doing VoIP on the WAN and VoIP on the LAN.
A lot of customers using an IP PBX continue to use their existing analog phone lines and integrate them into their LAN through the use of a VoIP gateway or a PCI card.
The two primary reasons to switch to a VoIP PBX are:

  1.   Cost 
      Flexibility

Cost of VoIP PBX

Here are some reasons why you would want to switch to a VoIP PBX system:
Traditional Keyed Systems become increasingly expensive to maintain with support contracts and on-site vendor visits.
VoIP PBX’s allow you to self-maintain with an easy to use graphical user interface, so you don’t have to hire anyone outside of your office for day-to-day or monthly upgrades and maintenance (with the possible exception of running straight asterisk). Integrate SIP Trunks and eliminate PoTs lines to decrease your cost on long distance and international phone calls. Multiple locations can dial IP PBX to IP PBX to make free phone calls, and allow extension to extension calling between branches. Connect your phones and PC’s on the same network, eliminating the need for additional wiring and cabling. Additionaly, most IP Phones have two 10/100 auto-sensing RJ-45 ports. This allows you to connect your VoIP phone to your network, and connect your PC to your network via the phones internal switch. And in situations with only one network connection available you will want to use a managed switch to manage the data traffic and voice traffic. Why is this listed as a cost savings? Most managed switches have optional PoE (power over Ethernet); allowing you to purchase just on UPS to backup all the phones on your network rather than putting an individual UPS at each work station.

Flexibility of VoIP PBX

VoIP PBX systems are extremely flexible because:
Open standards has allowed innovation, and thus an increased amount of products and subsequent competition which forces companies to increase customer service and decrease cost. Use almost any SIP Based IP Phone with any of the IP PBX’s offered on our website.  Growing companies can easily add new users on the system. Typically all that’s involved is the purchase of a new IP Phone. Comparatively, a proprietary phone system will require the purchase of various licenses and hardware modules. Conference calls, call transferring, auto-attendant, IVR, custom hours, and a number of other features can be set up just by clicking, dragging, and dropping a web administration menu making your day more productive, and the presentation of your business more professional.
