Asterisk is a fully-software PBX system. It can run on Linux, BSD, Windows (simulated), and OS X. It provides all the features you want from the PBX, and is more than the PBX. Asterisk supports four types of VoIP protocols. By using relatively inexpensive hardware, it can interconnect with almost all standard-based telephone devices.

We have introduced the features and structure of ROS. Next we will begin to prepare for the strong Ros. On the Wiki on the ROS official website, the tutorials for new users are very detailed. It is best to clarify all the tutorials for new users. This is the most basic thing for later development. Despite this, Ros is still difficult for beginners to get started. Here, I will summarize my learning history and serve
Imagine creating a library of wikis. Wiki sites contain content that users can create, delete, and modify interactively. Many wikis feature a simple, text-based markup language for creating content. Typically, these markup languages provide only a subset of the functionality available in HTML, but there is a simpler, clearer source format. For example, text that surrounds the asterisk is formatted as bold, and the underlined text is formatted as an un

Its operating principle is that the media gateway first converts voice to IP packet, and then to the media Gateway controller to control the management, and determine the IP packet in the network trans
"On the side of a PBX or bureau switch, a small amount of electrical energy is not fully converted and returned along the original path to form an echo." If the caller is not far from the PBX or switch, the Echo returns quickly and the human ear cannot hear it, which is irrelevant.
