What does FoIP mean?

[savio]

Hi,

I want to know what does FoIP mean? What are it advantage and disadvantages ??? And also if you can tell me how does it work ???

FOIP means 'Fax over IP' (fax over IP), and it states the process of sending and receiving faxes via a VOIP network. Fax over IP works through T38 and requires a VOIP gateway compatible with T38, as well as a fax machine compatible with T38, fax card or fax software. The fax server software can talk in 'T38' which lets you send and receive faxes through VOIP gateway, and therefore do not require any additional fax hardware.

Telephone connections are not only used for phone calls, but also to transfer of fax documents. But this application is voice-over-IP environments is technically not provided. Transfer documents as a fax with Voice over IP is difficult in general. Unlike phones, fax machines are vulnerable to even the smallest disturbance. They lead to an immediate loss of communication. Incomplete transmitted documents that are isolated from about half, are the rule. For this reason, there are standards to transmit fax documents via voice over IP. It assigns these standards, Fax over IP. Fax over IP has two standards. Once for T.37 store-and-forward transmission of Facsimilie and T.38 for fax transmission in real time.

Voice over IP (VoIP) and the fax service can be implemented over an IP network. This is called the real-time FoIP. In the real-time version of the fax is a direct connection is made to the recipient's terminal. In the faxes receive direct feedback on the submission process. The isochronous data is transferred there and the sending or receiving the fax document will take place almost simultaneously. Since the real-time FoIP is a real-time applications with strict real time requirements are compared to the IP telephony set higher requirements. When real-time FoIP synchronize the two fax machines and transmit their data directly through the connection.

Many of today's fax solutions used correspond to the so-called Super G3 devices. These operate according to the V.34 specification with speeds of 33,600 bit / s. The high speed is achieved through the utilization of total available speech frequency of the analog telephone network. Since this transfer is supported in a VoIP network, it is necessary to the modulation.

Through the coupling components on the route between sender and receiver and by the temporary occupancy falling latency (jitter) between the individual data packets on the network differently. The different delay times are of course bad for synchronously clocked applications. A far greater problem than the jitter, lost packets in FoIP. In contrast to VoIP is the transmission FoIP more prone to packet loss. Lost packages lead to a breakdown of the fax transmission. The effects of packet loss is heavily dependent on the type of fax machine and the type of error correction. It should be noted, however, that the error correction mechanism involves an increase in total delay departure.

FOIP specifies that any person has a right to access records in the custody and control of a local public body, subject only to limited and specified exceptions. The Foip being discussed here was a fax machine being plugged into an ATA.
