The Private Branch eXchange has gone full circle as a term. Originally having started as an organization’s manual switchboard (operated by a person plugging cables into sockets), they have evolved in to VoIP centers that are hosted by the operators or even hardware manufacturers.
What is VOIP?
VOIP is an acronym for Voice Over IP, or in more common terms phone service over the Internet.
If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company.
What is IP Phone?
An Ethernet hard phone is a self contained IP telephone that looks just like a conventional phone but instead of a conventional phone jack, it has an Ethernet port through which it communicates directly with a VoIP server, VoIP gateway or another VoIP phone.
What is Asterisk®?
Many people have seen the term Asterisk (either on our site or in other endeavors around the Web). So what is Asterisk? Asterisk is a free software / open-source software implementation of a telephone private branch exchange (PBX). Asterisk is unique in that it is interoperable with a huge number of devices and numerous protocols, including SIP and IAX, T1, E1, ISDN, PRI, FXO, and FXS. The basic Asterisk software includes many features previously only available in expensive proprietary PBX systems — voice mail, conference calling, interactive voice response (phone menus), and automatic call distribution.
Many customers ask us: "Why they just not use Asterisk since it is free instead of working with us?". Well, we believe people prefer to manage their business and not their phone system. So, for this reason we are offering value layers over the technology that Asterisk delivers at its core. They are:
Our management software includes Web-based administrators software which allows business owners to maintain their phone system from anywhere in the world with a simple web browser. Also a web-based User Panel, which is given to each employee of the company. This User Panel allows the employee to manage their extensions from anywhere at anytime. This includes listening to voicemails, click-to-call from their call logs, call forwarding and more.
Our customers can take their IP phones home and plug them into their Broadband modem. Their extension number and voicemail will follow them. They can then make calls, using VoIP, that route to their main office like they are sitting just at very own office desk.
You can monitor Asterisk system at real-time. Extensive reporting is also available at your fingertips whenever you want it.
