Systems that maps IP numbers to phone numbers from ravi teja's blog

The protocol that controls data transfer is called Transmission Control Protocol (TCP). After the connection is established, it starts the data transfer and when the transfer process is completed, it terminates the connection by closing the established virtual circuit. Extensive errors are easily found thanks to the error-checking feature of TCP. During peak network periods, transmission is delayed and unsent data is retransmitted. In short, TCP checks whether the data has reached the destination where it should be sent. It notifies with feedback whether data is transferred or not. The data transmission of the internet’s most popular protocols such as HTTP, HTTPS, POP3, SSH and FTP is done by TCP.


It collectively transmits the data to the other party without establishing a connection. It is used in real-time data transfer such as voice and video transmission in wide area networks (WAN). In addition, UDP is more preferred for games. UDP is an untrusted and generally not preferred protocol because it only transmits data according to the speed of the data generated by the application, the capability of the computer and the transmission bandwidth limit. UDP doesn’t think that every packet needs to reach the receiving end, so the network load is smaller than TCP. At the same time, the transmission speed is faster than TCP, but the congested the network the more risk it loses the packet sent. So what are the other differences between TCP and UDP?


It is very important that communication be effective and secure in the business world. Sharing the information in the right place at the right time facilitates the distribution of business processes. Some database services provide error-free management of IP phones and call decisions. With the given configuration commands, the nature of the communication is preserved and is not broken. The Linux-based communication server supported by Cisco Systems that maps IP numbers to phone numbers and integrates voice, video, data and mobile applications is called Cisco Unified Communications (CUCM) or Cisco Call Manager (CCM).
