VOIP IN DATAMINING
VOIP, a protocol
used to transmit the information in the form of voice through Internet connections. VOIP can be used instead of PSTN, in order to control the voice traffic. The VOIP (Voice over Internet Protocol) increases the flexibility of the delivering the discrete packets. Rather than PSTN (Public Switch Telephone Network), VOIP decreases the various network simulation occurs in the route. Various QOS (Quality Of Service) problems which are
managed by using the VOIP. A major advantage is that VoIP avoids the tolls charged by ordinary telephone service. VOIP protocol is used in the CMS, which is designed as fetching information from live website and sharing with users via VOIP so it will give more updated and reliable information at all the time. This system has enough security/permission groups to
ensure the security of information. The Real-Time Protocol (RTP) in the VOIP ensures that packets get delivered in a timely manner, where as in the PSTN does not guarantees the Quality of Service (QOS). Better service is possible with private networks managed by an enterprise or by an Internet telephony service provider (ITSP). Before establishing a Transmission Control Protocol sockets connection with the other end, the fastest path can also chosen by contacting all possible network paths to the public network to make the faster packet delivery. The PSTN
is now almost digital for both the mobile and fixed telephones. The design overview of using the VOIP consists of control and gateway nodes and the IP network(maybe Ethernet,Fiber,Wireless). It can also able to interact with all the intranets and internets and the Local Area Networks (LAN) without the QOS problems. The VOIP network includes the telephone which connects
to Public Switch Telephone Network which connected to the VOIP gateway router which makes to connect with the voice mail server used to store and retrieve the voice in the form of database. If the phone/mobile connected with the VOIP means which its connects to the Internet and there must be an enabled Firewall to interact with the other PSTN connected phones or VOIP connected phones. All the voice data in the form of discrete packets are supposed to store in the voice mail server. Fig:1 illustrates the VOIP and PSTN connected phones.
