Evaluate UC complexity Adding voice, video conferencing, and other real-time communications will suddenly increase Network Complexity and raise support requirements. It requires enterprises to fully evaluate their original organization models. This evaluation not onl

The Unified Communication solution provides many services, such as instant messaging, email service, and remote video conferencing. These services are based on the concept of enterprises. In addition, the cost of the Unified Communication solution is also very low. However, there are some misunderstandings that we should point out here.According to a survey conducted by CIOs in July this year for 413 IT purchasing managers, 32% of respondents have dep

If the user accepts the call, the customer uses the specified capability of the client software to respond to the request and establish a connection. If the user rejects the call, the session will be redirected to the voice mail server or another user. For "specify capabilities", refer to the featur

The continuous development of the Internet, the rise of a variety of new technologies, today I first listed the most basic development process, suitable for the development of video conferencing system, voice video chat system, distance education platform and instant communication platform ( IM ) and so on.

eavesdropping is to enable the switch to have a layer-3 awareness, and intercept IGMP messages sent between the host and the router to determine the location of the group members. CGMP enables the vswitch to understand group member distribution through Protocol interaction between the vro and the vswitch, but CGMP is a Cisco proprietary protocol. Multicast high-level protocol IP multicast cannot ensure reliable data transmission, and may cause packet loss, disorder, and duplication. Different p
