The PHP function does not find the called code, but it is executed at runtime (PHP beginners seek help) to ask this strange question I encountered. I am studying the elastix source code, is a web access interface of the softswitch system, and then I want to find back based on its operation database to find out how to operate from the original user (which button is pressed ). The problem is that I cannot find the called code for the PHP function, but t
reduced by the ability to transmit voice, video, and data over a converged IP network, the Unified Communication solution can save considerable costs for enterprises.Misunderstanding 3:In today's IP communication field, there is no super powerful application.Actual Situation: enterprises use the Internet for different reasons. similar to this, enterprises use Unified Communication for a variety of reasons. Currently, many Unified Communication applications can reduce costs, increase productivit
communication needs and telephone communication needs. However, because there are multiple independent parallel physical networks, there is no connection between them, the construction and maintenance costs are relatively high, and the O M is difficult.
According to the situation in China, apart from the construction of internal telephone systems by itself in specific industries such as power supply and public security, some of the general enterprises and institutions deploy their own data net
Communication solution runs through a smart phone. The supplier provides a special client software package for each mobile phone, thus limiting the user's choice of the device. If a user is used to a device that the mobile Unified Communication vendor does not support, there will be a huge controversy between the supplier and the user.
Mobile Unified Communication vendor
Mobile Unified Communication vendors can be divided into three categories: Unified Communication vendor, ip
The concept of softswitch was born
The concept of softswitch originated first in the United States. At that time, in the enterprise network environment, users used Ethernet-based phones to implement the PBX function through a set of Call Control Software Based on PC servers ). For such a set of equipment, the system does not need to separately lay the network, but can achieve unified management and maintenance only through sharing with the LAN, the ov
suitable for a wide range of applications, such as home, corridor, desktop, and IP supermarkets. However, IAD is a terminal device, which is inconvenient for management and maintenance.
Through the Access Gateway AG or the FXO port of the integrated access device IAD, the gateway can communicate with the PBX through the AT0 loop relay. The traditional old-fashioned PBX mostly accesses the softswitch networ
