For example, some modules can make your asterisk communicate with analog telephone lines, and some modules provide the function of traffic report. Later, we will also discuss the functions and categories of the various modules.Http://www.cnblogs.com/einyboy/archive/2012/11/08/2759969.htmlhttp://blog.csdn.net/yetyongjin/article/details/7520567SIP functionality for AsteriskThe Asterlsk can support t

Therefore, if the log function is enabled, access to the server may experience intermittent interruption when the log message on the control panel port is overloaded.Before starting the debug command, always consider the output and time consumed by the command. For example, if you have configured a router with a basic rate interface (BRI), debug isdn q931 may not caus

Tower of Hanoi: There are three adjacent columns, labeled as A, B, C, and a, stacked with N disks of different sizes in pyramid shape from bottom to top, how should I move all the plates one by one to Column B, and each time I move the same column, there cannot be big plates above the small plate? The tower of Hanoi is a very classic problem. It should be mentioned in recursion. If we do not have the prior knowledge of recursion to answer this question directly, we often feel that we do not know

When it comes to access networks, we must first involve a bandwidth problem. With the continuous development and improvement of Internet technology, the bandwidth of access networks is divided into narrowband and broadband. Industry experts generally think that broadband access is the future direction of development. The network structure of the broadband carrier is shown in 1. The entire city network consists of the core layer, convergence layer, edge convergence layer, and access layer. The a
