LRE technology uses orthogonal amplitude modulation (QAM ). The QAM amplitude modulation uses the signal amplitude and phase to define each symbol. LRE adopts the most advanced QAM technology, has a variety of QAM am QAM-256, QAM-128, QAM-64, QAM-32, QAM-16, QAM-8 and QAM-4 ). The system administrator can choose to adopt different amplitude adjustm

According to Edouard, the new QRadar module designed specifically to monitor VoIP networks meets this requirement. This VoIP module integrates network behavior analysis and security event Association to monitor the protocol, application, and security service layer of the entire network.
Tom Turner, vice president of marketing at Q1 Labs, said companies are working hard to monitor VoIP communication using security devices. Without effective monitoring, VoIP may experience bandwi

It usually refers to a switching device used in a telephone switching network, which controls the continuation of the telephone by computer. SPC is a telephone switch that u
Hotels that are unable to provide high-speed Internet access are a commercial disaster for international customers.

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.
Asterisk provides a director

The VoIP gateway acts as an interface for transmitting data from a traditional PSTN network to an IP network, through which you can call a network by using a traditional phone.
The ip pbx voice switch must not only take over the positions and functions of the traditional voice switch, but also become a medium for voice and information integration.
After an IP phone converts a voice signal to an IP packet, the ip

Service providers can deploy it on business access points (POP) or other remote sites, and extend the voice service to a wider area outside the coverage area of the Central Bureau.

"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. But when the echo returns more than 10ms, the human ear can hear the obvious echoes. In order to prevent echoes, the echo cance
