Asterisk PBX

Open source PBX software that runs under Linux and other Unix variants on a variety of hardware, including x86, PowerPC, POWER and Xscale. Supporting traditional telephony (TDM) as well as voice over IP (VoIP), Asterisk is written in C and uses the Unix standard POSIX programming interface to communicate with the operating system.

The IAX Protocol
Asterisk uses its proprietary Inter-Asterisk Exchange (IAX) protocol to initiate calls and send the data. Supporting any type of codec, IAX can be used for video as well as VoIP. All signaling and data ride in UDP packets, and IAX can multiplex multiple data streams between servers (port aggregation).

From Digium Et Al
Developed by Mark Spencer of Digium, Inc. (www.digium.com) and maintained by the company along with the Asterisk community (www.asterisk.org), a version for Windows that supported only VoIP was developed as a community project, but "AstWind" was later abandoned. Digium also offers a variety of analog and digital telephony interface cards that plug into PCI slots.

If a white dwarf were to survive such an event as a type Iax, the enormous energy of the explosion would give it a boost that would send it careening through space - it would have a "high kick velocity."
This suggests that Type Iax supernovas come from young star systems.
En el presente trabajo, se aplicaran los fundamentos anteriores para realizar calculos teoricos de consumo de ancho de banda, comprobando lo anterior, experimentalmente, por medio de la implementacion de una troncal fisica que sirva de enlace entre dos servidores de diferentes segmentos de red dentro de una LAN; con su correspondiente diseno arquitectonico y analisis de trafico en produccion, simulando cierto numero de llamadas simultaneas sobre los protocolos SIP (el cual usa el protocolo RTP para flujo de media) e IAX, para un numero definido de conversaciones.
In 1596, about four years before Twelfth Night was first performed, Sir John Harington published his satirical tract on the flushing toilet, A NEW DISCOVRSE OF A STALE SVBIECT, CALLED THE Metamorphosis of A IAX. The pseudo-Ovidian title is drawn from the Latin poet's account (which appears in Book XIII of Metamorphoses) of the Grecian warrior's metamorphosis into a purple flower.
Given a choice, they will focus their efforts on a target that offers the best chance of success - a victim whose personal security habits are Iax and whose patterns of activity are predictable.
VoIP services are implemented using various protocols such as H.323, Session Initiation Protocol (SIP), Inter Asterisk eXchange (IAX), Real Time Protocol (RTP), and Media Gateway Control Protocol (MGCP), among others.

SIP no fue el primero, ni es el unico, protocolo de VoIP usado hoy en dia (H.323, MGCP (Media Gateway Control Protocol), IAX (Jnter-Asterisk eXchange), entre otros), pero actualmente este parece ser el mas popular entre los fabricantes de hardware.
Currently boasting over 1 million users, Asterisk supports a wide range of TDM protocols for the handling and transmission of voice over traditional telephony interfaces, and VoIP packet protocols such as IAX, SIP and H.323.

Second, leverage DIDX's huge global footprint, features such as ringto SIP, IAX or Skype and market to potential and current clients the areas like Canada with great deals.
En los clientes solo fue necesario realizar una configuracion en los clientes IAX, pues todas las llamadas se harian manejando este protocolo, solo se debe declarar el servidor al que iran conectados.
