Description

SERVICE SYSTEM OF RINGBACK TONE FOR VOICE OVER INTERNET PROTOCOL TERMINAL AND METHOD THEREOF}

The present invention relates to a system for providing a ringing tone service for a VoIP terminal and a method of providing the same.

VoIP (Voice over IP) technology is a form of connection between a landline and an IP network, and by integrating telephone service using existing IP network, telephone users can make long-distance and international call service in the Internet and intranet environment with only local call charges. There is an advantage to receive.

In other words, VoIP is a term that refers to IP telephony technology for a series of facilities for transmitting voice information using an IP network. In general, this means that voice information is sent in digital form in discrete packets, rather than a traditional protocol based on a circuit, such as a public switched network (PSTN).

The main advantage of VoIP and Internet telephony technology is that it integrates telephone service by utilizing existing IP network network so that telephone users can receive long distance and international phone service in internet and intranet environment with only local call charge.

VoIP calls can be used by VoIP call users to locate other users to encourage the use of ITU-T, H.323, a standard for transporting voice and video over IP over the public Internet or intra-company intranets. It enables the use of touch phone signals for automatic telephone distribution and voice mail.

In addition to the original IP functionality, VoIP uses Real Time Protocol (RTP) to support packets arriving in a timely manner. Using public network networks makes it difficult to guarantee current quality of service (QoS), but better service can be achieved by using private networks managed by independent companies or Internet telephony service providers (ITSPs).
