What Is POC

Voice communication has become very easy as many different types of techniques have been invented to for communication according to the use and different environments that need the voice communication. In some environments the voice communication is so rapid that it is not possible to dial a number every time you want to connect to a user and then wait for him or her to answer your call. This problem has been eliminated by a technique call push to talk. This technique has also been introduced in the cellular networks by many service providers where the user can specify some special user or a group of users to whom they can communicate any tome they want without dialling any number or waiting for the call to be answered.

This is called push to talk over cellular s the cell phones and the cellular network is involved in this communication. This has become very successful and useful in many different environments where users had to interact with each other frequently. In this case a certain group of users can establish a connection between them as a single call connection and then they can communicate with each other simply. All they have to do is that only one person can speak at a time and then other can answer it.

Another benefit of this service is that if a user has no need to participate in that conversation he or she can only listen to it for any special detail or information that might needs attention otherwise they can continue with their work. It is also very fast way to send your vocal message to a lot of people at one time without the need of making different calls which save a lot time. This service is not very expensive as it can be continued for long period time.
