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

With the rapid development of mobile communication technology, we are brought into the colorful 3G multimedia Information age. In particular, the rapid development of the Internet, more and more users can use faster, cheaper Internet connection, which makes such as chat applications, video voice, online games, such as the need to continue online applications to achieve the possibility. The traditional telecom network is designed for the telephone b

There will be some business in operation network, such as: VoIP Access Service, enterprise users in the complex building, etc., the VLAN ID can be used as the identity of access control, and different access control strategies are adopted for the network devices with different VLAN IDs under the same physical interface.

Much of what the site does (for example, its ability to support different languages and the ability to conduct secure e-commerce transactions) depends on the functionality provided by the hosted Web serverSuppose Joe's hardware store and Mary's Antique auction store
Taking the implementation of the data backup function of the Communication soft switch as the research object and focusing on the comprehensive application of the computer platform, this paper briefly analyzes the design idea of the Data Backup System of the Communication soft switch based on the computer platform, on this basis, the design scheme of data backup system for communication soft Switches Based on the computer platform is analyzed from the hardware design and software design, the sim
NGN devices. Viruses and hackers generally threaten devices that use general operating systems, such as various servers. Security issues of user services mainly include: User counterfeiting, theft of other users' accounts and permissions to use the business; Illegal listening to the call information or media stream content of other users' calls.
In terms of the technical security framework of the NGN access network, we can divide the NGN access network into four areas: trust zone, non-trust zon
rapidly cultivated a large number of user groups. This phenomenon provides a lot of meaningful inspiration for fixed network operators and mobile network operators: IP-based multimedia applications will be the core competitiveness for users and increase the ARPU value. In addition, compared with the traditional TDM signaling service implementation method, the IP-based service implementation method is convenient, flexible, and fast. Therefore, fixed network operators and mobile network operators
Based on the needs of network convergence, from a technical perspective, 3G/PHS network convergence is feasible.
Background of PHS and 3G network convergence
As an important source of income for fixed-line Chinese telecom operators, PHS has contributed and contributed to fixed-line telecom operators. How to combine Problems in the Development of the PHS network, expand the PHS network business in depth, constantly improve the network structure, explore the value-added services of the PHS network

Developed for SIP/IMS video clients, supports access to sip Softswitch, IMS core network, andVoice, video, and instant messaging functions. The video formats support h263, h264, and MPEG4 soft encoding solutions. The hardware coding/decoding interface is provided for interconnection and servers. If you are interested, contact me.

Interoperability: (1) interoperability between versions includes the full backward compatibility of H.323, enabling seamless integration for all different H.323 versions. In terms of SIP, the new version may prevent some old functions from being implemented. (2) interoperability with other Signaling Protocols: to support traditional telecommunication services, the VoIP signaling protocol must support the interfaces of ISDN and No. 7 signaling q.931 for the user-Network Interface

Starting from this event, I began to learn Microsoft's Visual C ++/mfc-a fast development environment that is hard to find even the main function entry, and began to give up the previous basic knowledge learning, A series of Microsoft tricks appear in my focus, such as ODBC, COM interface, DCOM, COM +, and OLE (Fuck TMD Microsoft ), there are other petabytes, dephi, and VF tricks, but I am totally lost in these tricks.

With the development of cloud computing technology, compared with traditional servers that run applications directly, virtual machines run on servers, and applications run on virtual machines are becoming more and more common.
In this case, the network is often the most critical performance bottleneck, especially how high-speed network traffic between different virtual machines can be effectively exchanged.
To solve the problem of large traffic switching, there are basically two simple ide
