Equipment / technical equipment, Voice over Internet Protocol

Any application VoIP requires a power source supported by the network as well as high capacity and the most important equipment that we will need: - Analogue telephone adapters Analog Telephone Adaptors ATA -: - The analog phone adapter ATA link any normal analogue phone network with Voice over Internet Protocol. This converter on a port type RJ-11 (port phone) and another port of the type of RJ-45 (port Ethernet Ethernet) thereby acting this converter to convert audio signals analogue of the normal phone analogue signals to digital and can be connected to ATA on any type of phones and ATA is a VoIP Gateways Mobile code Soft phone: - You can buy a replacement phone for Voice over Internet Protocol installed the program does the same task within the personal computer, which is known as the "phone code" Soft phone. This program requires no more than provide a sound card, speakers, Msdh (microphone) in addition to making sure that your firewall does not prevent his personal exemplified (Net2Phone-PC2Call). Mobile Voice over Internet Protocol VoIP Phone: - Equipment is specially designed for this purpose is linked directly with the VoIP network and did not need any additional equipment, such as ATA and did not need to download any software. Can operate according to these phones and the Internet Protocol one or more. Important features that you should inspect when buying a mobile Voice over Internet Protocol: - Consumption is simple to view the package: support mechanisms developed pressure) such as G.729 Speex). Interface provides easy management: working across the Web. Port for the vote: exit for the voice with the possibility of connecting headphones) for distance training applications (. Mobile Voice over Internet Protocol wireless Wi-Fi/WLAN Phone: - Equipment is specially designed for this purpose is linked with the VoIP network such as the former, but the difference only that it be connected to the network wirelessly via the access point Access Point. Cards with a network linking public switches telephone PSTN interface cards: - If you want to route calls from the equipment that operates according to Voice over Internet Protocol to the traditional telephone network PSTN will need to install some special equipment for this purpose within such Mksmk card PCI TDM400P wildcard. [Edit] Some success stories using a technology called Voice over Internet Protocol
[Edit] System VoIP gives State Hospital Carolania some calm The Hospital of the University of North Carolina - United States - get rid of the old regime Paging Overhead and through which the nurse requested through loudspeakers. The objective is to reduce the noise the old system of internal communication and protests that patients are not taken delivery of their applications as required. In the previous period was the hospital's patients when they want to request a specific request it through the device next to the bed and is receiving contact our hospital and the officer will record the patient's request and then dials the pathogen through the intercom system (speakers sound) to convey the patient's request. Intercom system offers the service was not fast enough and ineffective does not serve the nurses properly because the nurse needs to direct contact with the patient and not through a third party (the receptionist) In addition to the noise caused by this system. The solution to this problem through the work of a wireless network to facilitate the work of doctors put patients directly on their portable computers. The hospital using the technology VoIP Abbarbrocokol the Internet to connect patients and nurses directly were distributed to more than three hundred cordless phone on the nurses and linking devices be close to the family of patients, allowing the patient to connect wirelessly to Balmamrd The nurse answered by wireless phone carried by ensuring no hassle delivery their requests clearly. [Edit] The units communicate over the Internet Protocol in the State of New Orleans without the benefit after Hurricane Katrina After Hurricane Katrina hit New Orleans and state - United States - were cut off communications for thousands of families trapped by the flood. After the hurricane destroyed most of the facilities were not shining charities to communicate with their loved ones, including the Organization: Catholic Charities Archdiocese of New Orleans (CCANO). And before the flood and Hurricane Katrina, the institution intends to activate the system, RingCentral, a system to link all staff with the institution and the system uses a technology called Voice over Internet Protocol before the storm was the system under test. The organization intends to improve communication and emergency plans in the event of a disaster. During the hurricane most of the telephone lines were cut off and mobile phones were out of coverage. The new system will determine if the run-stricken areas and necessary through personal contact with staff and determine the situation after the disaster by sending sufficient information and the necessary support for people in distress and in need of help. And after this storm has caused damage and disruption from the outside world out of organizations and institutions studying, is the need to keep contact with all the circumstances and not only through traditional communication that could be cut off completely, but we should rely on modern technology as well, such as Voice over Internet Protocol.

Definition of technology transfer voice over the Charter network

It stands for an English Voice Over Internet Protocol (ie Voice over Internet Protocol) - is a way to bind voice conversations over the Ahabkp (Internet) or via any network that uses Internet Protocol Internet Protocol. And therefore can be any number of people connected together to a single network using Internet Protocol (IP) - such as the Internet - that Ithadthoa phone using this technique. [Edit] the principle of technical work
The technology converts audio signals analogue Analog Signals from the phone into digital signals Digital Signals are split this signal into packets Packets and uses the IP to send these packets of digital several paths through the same network data and upon the arrival of these packets to the specified destination (future) re-compilation packets sent in order to be heard clearly in contrast to the usual contacts are using one path is selected and if the other party (the future) a normal phone signal is converted back to acoustic signals in order to be understood in the future. [Edit] Steps technical work Convert analogue signals Analog Signals to Digital Signals Digital Signals. Compression packages are good (the bandwidth is too small), there are several Muaiq (protocols) can choose to compress the package, including more sophisticated, so do not get delay in the sound. The integration of voice packets within the packet data using Meevaq (Protocol) real-time RTP-Real Time Protocol. We need to contact the user signals (bell) ITU-T H323. At the receiver are analyzed package and extract data from them and convert digital signals to the audio again and sent to the phone. Should happen in real time Real Time in order not to get cut in the sound. [Edit] requirements necessary for the work of technical
You must use the PBX to determine the course of conversation. Convert audio signals Analog Signals to Digital Signals Digital Signals. The use of Internet Protocol IP. Must divide the digital signal into small pieces called packets digital transfer of several paths through the network data itself. You must press the packages are good (the bandwidth is too small), there are several protocols can choose to compress the package, including more sophisticated, so do not get delay in the sound. There should be a place for temporary storage to collect packets Buffer in order not to be a delay in the sound. Should happen in real time Real Time in order not to get cut in the sound. [Edit] technical standards for Voice over Internet Protocol
A set of rules and conditions that govern the process of telephone calls and are divided into: - [Edit] Closed systems And are based on standards (closed not free source) programs such as Skype and IP Cisco famous (Skinny Client Control Protocol SCCP), a protocol is closed to control Balpartyyat developed mainly by the company Celsius Selsius Corporation, owns and develop specifications now Cisco Cisco System Inc. Among the most famous equipment operating in accordance with this Protocol Series, Cisco 7900. [Edit] Open Systems Includes open standards-based protocols such as open-source: - Protocol H.323: - Is a set of standard protocols emanating from the system developed by the International Telecommunication Union ITU-T for the NFL audio and images via computer network packets using the Packet-Based This protocol is used in the majority of popular applications such as NetMeeting. Protocol SIP: - Is an acronym for Phase Initiation Protocol, a protocol for telephone signals associated with Internet protocols, which are used to start, modify, and terminate phone calls from the type of VOIP. The teams have developed Internet Engineering Task Force IETF to this Protocol, have been published on the RFC 3261 protocol at the beginning. Possible for SIP to describe the communication is necessary to start the phone call became the start of phase protocol as a boom in the world of mobile VOIP. This Protocol is largely semi-protocol HTTP, the protocol that script, and easy to understand, and flexible to use, but it was resolved the SIP protocol H323 replaced the standard in use on a large scale.
Protocol IAX2: - A protocol to communicate between the programs, a program Asterisk Asterisk Open Source PBX telephone and provides voice over Internet protocol between Asterisk servers Asterisk and IAX2 clients and the package well under pressure. To get an idea of ​​the size of waste produced during the transfer of voice over the Internet, remember that the audio CD, which occupies an area of ​​5.6 kilobits per second will need to 18 kilobits per second of bandwidth, comprising the difference between 5.6 Kbps and 18 Kbps of the headers of packets that will carry the data. This header contains all the necessary information (such as IP Address) for the transfer of voice packets to the future. We have the IAX2 protocol to reduce this waste is a wonderful bits by determining the amount of the additional permitted use for each package, and also took advantage of the principle of compilation of the talks sent to the same destination and included in the same packages.

History of technology transfer voice over the Charter of the Internet

Technology VoIP Charter of the network (VoIP) came to change the traditional phone world. The traditional phone lines tend to slow gradually as offered by VoIP technology in all parts of the world the benefits and advantages in advanced technology. It is useful to stop and look at the history of VoIP and you will find a more exciting future. Date IT technology transfer voice over the Charter of the network (VoIP) shows that this technology began in 1995 when he started a small company called vocaltec, was believed to be the first Internet telephone program. This program was designed to run on a home computer and is very similar to telephones in use today, and they are using sound cards and Almassadh (microphones) and speakers. And it was called the program "Internet Phone" and uses the Charter of the H.323 instead of the Charter of the SIP, although it is becoming more common today . Vocaltec company began its success with Internet Phone, and was successful in 1996. The main disadvantage, which appeared in 1995, is the lack of network capacity petition Broadband, and on this basis, this software is used for modems that resulted from poor sound quality when compared with a normal phone call. It is also useful to note that none of the staff vocaltec key is also the founder whichvoip.com. By 1998, the rate of use of VoIP traffic to represent approximately 1% of all voice messages in the United States. And became all eyes to the preparation of the devices that enabled the connection PC to Phone PC-to-phone and phone to phone phone-to-phone . And provided networking companies like Cisco and Lucent equipment that can run VoIP Traffic As a result, by the year 2000 became a stream VoIP represents more than 3% of all voice messages. And well known companies and leading company in this area Skype that have emerged in the mid-nineties and there are a variety of other programs such as, Net2Phone, PC2Call, ZeroPhone ..... In 2005, the issue of ensuring the quality of voice takes priority over data transfer this technology to become more reliable for the transfer of voice and clear without interruption of telephone calls. Is expected to reach sales revenue of VoIP equipment alone, more than 8.5 billion dollars by the end of 2008. That the rate of exponential growth and rapid VoIP technology with the use of wireless technologies, the future of this technology is really exciting surprise.

Voice over the Charter of the Internet (Internet Protocol) Voice over IP or VoIP is a way to bind voice conversations over the Internet or via any network that uses Meevaq Ahabkp Internet Protocol. And therefore can be any number of people connected together to a single network using Meevaq Internet (IP) - such as Ahabkp (Internet) - that Ithadthoa phone using this technique. Referred to the companies that transfer voice over internet provider service companies, referred to Meevaq (Protocol) which transfers audio signals across the Internet Bmeevaq (protocol) Internet VoIP.
introduction
In 1995 began some amateur to realize that the sound can be transferred over the network (the Internet) instead moved for a way of telephone lines only, which users can network linking parts of the world to provide the large amounts they pay for international telephone traffic where he was developing the first computer program able to its users to communicate with each other not only requires a sound card and microphone and connecting to the network (internet). These programs were not at that time enjoyed the purity of sound and quality desired but it was the indicator that the process of transfer of sound through Ahabkp possible and promising. No longer a telephony Ahabkp limited to computers only, especially after that it is now possible to use the services (VoIP Charter (protocol) Internet without even having to run the computer through the phones that support this technology. It should be noted that communication technology across the Charter of the network ( Internet) technology based on software, which benefit from Voice over the Charter network VoIP in the transfer of voice and data Ir a computer network. These include innovative technology features high-many of them on but not limited to: transfer calls, and conferences group of remote (distance), and voice messages, etc., and to enhance communications networks and reduce the total cost. for the use of IT services, Voice over the Charter of the network is not just the use of Compass Internet with a wide range, such as service lines, fast Internet (De. S. Al) and one marches (Routers) equipped with Internet and telephone links .
