There are two ways to use IAXmodem with static or dynamic libraries. If there is any machine in its version of spandsp or libiax2 different to those included with IAXmodem it is best to use static libraries (eg for distributions as trixbox preinstalled or similar) otherwise to make an installation dynamics.

VoIP - Voice over Internet Protocol (also called IP Telephony, Internet telephony and Digital Phone) is the routing of voice conversations over the Internet or any other IP-based network.
SIP - Session Initiation Protocol - is a protocol developed by the IETF MMUSIC Working Group proposed standard and to initiate, modify and complete an interactive user session that involves multimedia elements, such as video, voice, instant messaging, online games and virtual reality. PSTN - public switched telephone network - is the concentration of public networks of circuit-switched world, like the Internet is the concentration of global public network packet-switched and IP-based. ISDN - Integrated Service Digital Network - is a type of telephone system of circuit-switched network designed to enable the digital transmission (as opposed to analog) voice and data over copper telephone wires common, which means better quality and faster than the available with analogue systems. PBX - Switchboard (also known as the Telephone for Private Business) - is a telephone exchange owned by a private company, as opposed to the plant that is owned by a telecommunications operator or a telephone company. IVR - in telephony, interactive voice response - is a computer system that allows a person, typically the caller on the phone, please select from a menu of voice and interface with a computer system. DID - Direct Dialing internal (also called DDI in Europe) is a feature offered by phone companies for use with the switchboard of its clients through which the telephone company assigns a range of issues connected to the switchboard of his client. RFC - Request for comments (the plural is Requests for comments, in which case its acronym in English are RFCs) is one in a series of briefing papers numbered Internet standards and that both commercial and freeware software on the Internet and communities Unix still widely.
Ericsson’s (news - alarm) multi convergence communication system is the convergence MD110 communication system, a system that integrates well fixed and mobile telephony, IP phones, softphones PC, cordless telephones, cellular / mobile phones, digital phones and IP Gateway. MD110 convergence communication system supports cost-effective, seamless voice communications through corporate networks, intranet, LAN, WAN, and public networks. Through convergence, companies will have the power to be productive by capitalizing on real-time, mission-critical business applications and communications. Now full IP networking between MD110 and BusinessPhone allow convergence on existing IP connections, making it extremely flexible working methods and better cost efficiencies. The dynamics of network administration, DNA, IT managers gave the choice to manage the network from a single point or more points. You can manage a network of any size, simply by adding DNA server and liaison between them over a WAN together. And you can distribute management responsibility to persons designated anywhere within the network, each with different levels of access.
Voice Over IP is a new communication means that let you telephone with Internet at almost null cost. How this is possible, what systems are used, what is the standard, all is available these days if you google.
The past – More than 30 years ago Internet didn’t exist. Interactive communications were only made by telephone at PSTN line cost. Data exchange was expansive (for a long distance) and no one had been thinking to video interactions (there was only television that is not interactive, as known).
Yesterday – Few years ago we saw appearing some interesting things: PCs to large masses, new technologies to communicate like cellular phones and finally the great net: Internet; people begun to communicate with new services like email, chat, etc. and business reborned with the web allowing people buy with a “click”.
Today – Today we can see a real revolution in communication world: everybody begins to use PCs and Internet for job and free time to communicate each other, to exchange data (like images, sounds, documents) and, sometimes, to talk each other using applications like Netmeeting or Internet Phone. Particularly starts to diffusing a common idea that could be the future and that can allow real-time vocal communication: VoIP.
The future – We cannot know what is the future, but we can try to image it with many computers, Internet almost everywhere at high speed and people talking (audio and video) in a real time fashion. We only need to know what will be the means to do this: UMTS, VoIP (with video extension) or other? Anyway we can notice that Internet has grown very much in the last years, it is free (at least as international means) and could be the right communication media for future.
