On constructing enterprise open source VoIP with asterisk

Many people want to know whether it is possible to build an enterprise-class open source VoIP solution and whether it is good to do so. This paper gives some positive answers to this question.

Asterisk not only serves as an IP call signal server (sometimes called an IP PBX), but it also acts as a traditional tdm/analog PBX and bridges seamlessly between the two environments.

In Figure A, we have an enterprise-class hybrid ip/tdm/analog telephony solution. Note that there is no "pure" IP solution because analog devices and analog phone pots (ordinary old phone service) environments cannot be circumvented. Sometimes companies have to support a simulated fax or analog telephone port for certain businesses. The only problem is the number of analog and IP phones you use, and who is using them.

In my "open source VoIP" diagram, the solution consists of several key components:

IP PBX (asterisk server)

Voice mail and Fax server

Ethernet to the T1 bridge

Channel Processing Unit

Ethernet swap segment (LAN marked with thick pipe)

Analog phone

Analog Fax

IP PBX (Asterisk server)

A PBX is a broad generic term that usually refers to a type of central device that controls all telephones. An IP PBX is a very loosely defined term that usually means a class that establishes and negotiates IP to IP telephony or IP

A call signal sending server to an analog pots (normal old-fashioned phone service) call. The PBX typically also manages the telephony system. In our particular chart, we have two redundant asterisk servers that serve as IP PBX solutions. The asterisk server hardware in this scenario can be a "white box" 1U server with a normal value of $1000 to 2500 dollars, or a branded server from Ibm,dell or HP worth 1500 to 5000 dollars. The benefit of Asterisk software is that it can run on common x86 Intel or AMD hardware, saving a lot of cost over its proprietary PBX system, which costs dozens of times times the cost.
