VoIP: essential knowledge for voice managers

Like Voice over IP (VoIP), from the beginning of the network economy boom, IP Network Videos are both popular and challenging. We have already experienced fraud when purchasing too much, and now most customers have become sophisticated, buyers and IT departments have become more realistic about when and how their users use video systems. In this article, we will mainly talk about how voice managers or network managers should make decisions on this issue.

VoIP Classification

Here is a simple classification description of the IP network video.

Streaming media ):It is mainly used for single-channel video content distribution, such as the CEO's broadcast to employees, security warning videos, and various trainings. A popular stream transmission deployment feature is that video content can be stored on the edge of the network, and users can access it on demand. This is a video that benefits from the multicast technology.

Video Conferencing (Conferencing ):Whether it's two people, two rooms or six rooms, This is a variant of the "head being discussed" of an IP video. Many old video conferencing systems skip the IP address and run videos on ISDN.

Telepresence ):This is a relatively new thing. It tries to provide a more real user experience for high-definition videos, images that can be scaled at will, space-sensing sounds, and other features. Theoretically, it allows users to use all the body language and written or non-written communication methods, which are not possible for traditional video conferencing.

Now, we should know something...

Terminal:This is the device you use to watch videos. At least they need to include a video camera and a certain TV device. You can choose a large "indoor system" that includes a set of dedicated devices that can reproduce the entire conference room, or a notebook or desktop with a video player and Network Camera, or some devices in the middle.

The main decision here is to use the minimum overhead to build a shared system for a conference room and compare the overhead of "desktop video" convenience and features. If you want to run a video on the desktop, you must confirm that you have installed a LAN and prepare support for handling various user needs, for example, when they try to run 30 programs at the same time, they complain about the poor Frame Rate and when they are working on mobile phones.

Transmission:This is how you can send videos from one terminal to another. If you use an IP address, you can choose to use the data Wan in your organization or create a dedicated video network. ISDN is also a good choice-or it may be a good method based on your region.

Extended Gateway: This is how you connect to the video system not only on your company's network. First, you need to determine whether this is a requirement. That is to say, is there a need for people in your organization to use video conferencing. If yes, you can create your own gateway on the Internet or ISDN, or purchase a gateway service from the WAN provider or other service providers.

Integration:This is how to connect your video system to other IT systems. Popular options include connecting your video system to your email and calendar program, so that you can arrange meetings and meeting rooms, or connect it to the instant messaging system and other data cooperation systems to make it easier to use, allowing users to use a PC program to share images or work together.

What a VoIP manager needs to know is the effect of video on QoS and the potential integration of VoIP. First, QoS video streams need to be classified and protected against data streams. It is difficult to reserve bandwidth to ensure proper queue size. Before deploying the service, you must confirm that your call management control is running. Secondly, if you have both VoIP and video conferencing systems, this is a good opportunity for some of your users to use video phones and to allow users who only have voice communication capabilities to join video conferencing, in this way, the voice user uses the VoIP System in your network.
