  3. What Is NetMeeting? NetMeeting enables you to communicate with others over the Internet or your local intranet. Using NetMeeting you can: • Use data conferencing tools between an unlimited number of participants • Use audio and video between two people • Share and collaborate on applications • Use tools such as chat, whiteboard, and file transfer • Control the desktop remotely

  4. NetMeeting Technology • Microsoft NetMeeting is a VoIP and multi-point videoconferencing client included in many versions of Microsoft Windows (from Windows 95 OSR2 to Windows XP). It uses the H.323 protocol for video and audio conferencing, and is interoperable with OpenH323-based. It also uses a slightly modified version of the ITU T.120 Protocol for whiteboarding, application sharing, desktop sharing, remote desktop sharing (RDS) and file transfers. The secondary Whiteboard in NetMeeting 2.1 and later utilizes the H.324 protocol.

  5. NetMeeting Technology • NetMeeting is a software application for audio and video conferencing. NetMeeting offers sharing of desktop video, audio, chat and file transfer functionality. • NetMeeting supports directory servers and services. NetMeeting uses may automatically register with a directory when they start their NetMeeting client. The directory then allows users to find online users by name or location. If no directory is available, NetMeeting users can also call each other directly by computer name or IP address. • Once connected to other users, NetMeeting places all parties in a "call." NetMeeting tracks the call roster and allows users to share their desktop windows, to chat, transfer files, or share a VoIP feed.

  6. Voice Over Internet Protocol • VoIP is a technology that allows telephone calls to be made over computer networks like the Internet. VoIP converts analog voice signals into digital data packets and supports real-time, two-way transmission of conversations using Internet Protocol (IP).

  7. Voice Over Internet Protocol • VoIP calls can be made on the Internet using a VoIP service provider and standard computer audio systems. Alternatively, some service providers support VoIP through ordinary telephones that use special adapters to connect to a home computer network. Many VoIP implementations are based on the H.323 technology standard.

  8. Voice Over Internet Protocol • VoIP offers a substantial cost savings over traditional long distance telephone calls. The main disadvantage of VoIP is, like cell phones, a greater potential for dropped calls and generally lesser voice quality.

  9. H.323 Protocol • H.323 is a protocol standard for multimedia communications. H.323 was designed to support real-time transfer of audio and video data over packet networks like IP. The standard involves several different protocols covering specific aspects of Internet telephony. The International Telecommunication Union (ITU-T) maintains H.323 and these related standards.

  10. H.323 Protocol • Most voice over IP (VoIP) applications utilize H.323. H.323 supports call setup, teardown and forwarding/transfer. Architectural elements of a H.323 based system are Terminals, Multipoint Control Units (MCUs), Gateways, an optional Gatekeeper and Border Elements. Different functions of H.323 run over either TCP or UDP.

  11. OpenH323 PROTOCOL • Full featured, open source implementation of the H.323Voice over IP protocol. The code is written in C++ and, through the development effort of numerous people around the world, fully supports the H.323 protocol. The software has been integrated into a number of open source and commercial software products.

  12. ITU T.120 PROTOCOL • ITU-T recommendation that describes a series of communication and application protocols and services that provide support for real-time, multipoint data communications. It is used by products such as CiscoWebEx's MeetingCenter, MicrosoftNetMeeting and Lotus Sametime to support application sharing, real-time text conferencing and other functions.

  13. Transmission Control Protocol • Transmission Control Protocol (TCP) and Internet Protocol (IP) are two distinct network protocols, technically speaking. TCP and IP are so commonly used together, however, that TCP/IP has become standard terminology to refer to either or both of the protocols. • IP corresponds to the Network layer (Layer 3) in the OSI model, whereas TCP corresponds to the Transport layer (Layer 4) in OSI. In other words, the term TCP/IP refers to network communications where the TCP transport is used to deliver data across IP networks. • The average person on the Internet works in a predominately TCP/IP environment. Web browsers, for example, use TCP/IP to communicate with Web servers.

  14. UDP Protocol • UDP is a lightweight transport built on top of IP. UDP squeezes extra performance from IP by not implementing some of the features a more heavyweight protocol like TCP offers. Specifically, UDP allows individual packets to be dropped (with no retries) and UDP packets to be received in a different order than they were sent.

  28. How to establish a connection in MS Netmeeting for Windows XP • Press Start and then run. • Type conf • Go through the directions and fill out any required fields. • Once you have done this press call -> New Call • Type in the ip address of the person to call and press call.

  29. How to establish a connection through a firewall • When you use NetMeeting to establish a connection over the Internet, NetMeeting uses several IP ports to communicate with other meeting participants. • NetMeeting uses the following Internet Protocol (IP) ports: • Port Purpose • ------------------------------------- • 389 Internet Locator Server [Transmission Control Protocol (TCP)] • 522 User Location Server (TCP) • 1503 T.120 (TCP) • 1720 H.323 call setup (TCP) • 1731 Audio call control (TCP) • Dynamic H.323 call control (TCP) • Dynamic H.323 streaming [Realtime Transport Protocol (RTP) over User Datagram Protocol (UDP)]

  30. How to establish a connection through a firewall • To establish outbound NetMeeting connections through a firewall, the firewall must be configured to do the following: • Pass through primary TCP connections on ports 522, 389, 1503, 1720 and 1731 • Pass through secondary UDP connections on dynamically assigned ports (1024-65535).

  31. How to make a video call with Net Meeting • To receive video, all of the following conditions must exist: • There must be a user capable of sending video. • The user capable of sending video must be sending video to you. • If you are receiving the video, the status in the video window should read "Receiving." If the status reads "Paused," you will not receive live video until you click the Play button to resume play.

  32. How to make a video call with Net Meeting • To send video, all of the following conditions must exist: • You must have appropriate video hardware that is compatible with NetMeeting: a camera or a video capture board. • The user sending the video should see the "Sending" status in the My Video window. Video is not sent if the status is "Paused."

  33. How to make a video call with Net Meeting • Making an Audio and Video Connection • NetMeeting establishes a video connection automatically at the beginning of the call if the Automatically send video at the start of each call check box is selected. • If you are in a data conference and do not have an audio and video connection established, you can right-click a user on the Current Call tab, and then click Switch Audio And Video. • You can also click Switch on the toolbar, and then click to select the user with whom you want to establish an audio and video connection. Note that the Switch button is available only when the Current Call tab is selected.

  34. How to Share programs in Net Meeting • NetMeeting allows you to share programs running on your computer with other NetMeeting participants. Programs can be shared even when a participant does not have that program installed on his or her computer. • When you are in a NetMeeting conference, others in the conference can see and use a program running on your computer.

  35. How to Share programs in Net Meeting • To share a program within NetMeeting, click the Tools menu, point to Share Applications, and then click the program to share. Or, you can click the NetMeeting icon on the taskbar, point to Share Application, and then click the program you want to share. Or, you can click the Share button on the toolbar displayed for the current call. • When you select a program, it is seen on every other computer in the conference. The name of the program's owner is displayed in the upper- right corner of the window (if that window is not maximized). • By default, you are in control of the program. You can click Collaborate on the Tools menu, or click the Collaborate button on the toolbar for the current call, to allow others to use the program. In this mode, the initials of the participant who has control are added to the mouse pointer. Any user can change or run your program after taking control of the program by double-clicking the shared program.

  36. How to Share programs in Net Meeting • Program sharing is achieved by passing graphics, mouse movements, and keyboard inputs to the other computers in real time. Your color and resolution settings have an impact on how items are displayed on other computers. If the originator of the shared program is using 1024 x 768 screen resolution, but a participant is using 640 x 480 resolution, the participant's screen will be too small to display the whole window.

  37. How to transfer files in Net Meeting • When you are in a NetMeeting conference, you can transfer a copy of a file to every participant in the conference. • You can transfer a file by dragging the file's icon to the NetMeeting window for global file transfers (transfers to all conference members), or by pointing to a single participant. To initiate a global file transfer, you can also click File Transfer/Send File on the Tools menu. • You can initiate individual file transfers by right-clicking a participant in the roster and then clicking Send File. In most cases, you see the Browse dialog box. If you use the drag method, no dialog box is visible.

  38. How to use chat in Microsoft Net Meeting • NetMeeting includes a Chat tool that allows online meeting participants to communicate with each other using standard text messages. Chat is particularly useful when one or more meeting participants is unable to use the audio features of NetMeeting. • To start Chat, click Chat on the Tools menu in NetMeeting, click the Chat button on the toolbar, or click the Chat icon on the menu from the NetMeeting icon on the taskbar.

  39. How to use chat in Microsoft Net Meeting • Chat includes the following features: • When one person in a meeting runs Chat, it appears on all screens. Everyone in the meeting can then type messages simultaneously and see what other people are typing. • You can specify the font and font size, style, and effects that are used for the messages and information display in the Chat window on your computer. • You can specify the items included in the information display associated with each message in the Chat window and the format used for the messages. • You can save the current contents of the Chat window so they can be opened in NetMeeting, Microsoft Excel, or another spreadsheet or word processing program in the future.

  40. How to make a Video Call in Net Meeting • In Microsoft NetMeeting, you can participate in a video conference with other NetMeeting users. • To receive video, all of the following conditions must exist: • There must be a user capable of sending video. • The user capable of sending video must be sending video to you. • If you are receiving the video, the status in the video window should read "Receiving." If the status reads "Paused," you will not receive live video until you click the Play button to resume play.

  41. How to make a Video Call in Net Meeting • To send video, all of the following conditions must exist: • You must have appropriate video hardware that is compatible with NetMeeting: a camera or a video capture board. • The user sending the video should see the "Sending" status in the My Video window. Video is not sent if the status is "Paused."

  42. How to make a Video Call in Net Meeting • Making an Audio and Video Connection • If you are in a data conference and do not have an audio and video connection established, you can right-click a user on the Current Call tab, and then click Switch Audio And Video. • You can also click Switch on the toolbar, and then click to select the user with whom you want to establish an audio and video connection. Note that the Switch button is available only when the Current Call tab is selected.

  43. Where is NetMeeting going today? • NetMeeting helped pioneer online conferencing when it was released in May 1996, before the advent of instant messaging (IM) and other services for real-time online communication. • The software still ships as part of Windows and some of its features, such as whiteboarding and application-sharing, are used by the MSN Messenger and Windows Messenger IM applications.

  44. Future of NetMeeting • NetMeeting is no longer included with Windows Vista, and has been replaced by Windows Meeting Space and Microsoft office Live Meeting. • However, a hot fix for Vista was published by Microsoft on March 22, 2007. • The hot fix contains an installer package to install NetMeeting 3.02 on Windows Vista business, enterprise or ultimate versions. Version 3.02 is essentially a port of 3.01 to Vista. Net meeting doesn't work with Vista Home edition.

  45. Future of NetMeeting • NetMeeting can still be installed and run on Windows Vista. A hotfix for Vista was published by Microsoft on March 22, 2007 can obtain this hotfix by contacting Microsoft Support. The hotfix contains an installer package to install NetMeeting 3.02 on Windows Vista business, enterprise or ultimate versions. Version 3.02 is essentially a port of 3.01 to Vista. Netmeeting doesn't work with Vista Home edition.

  46. Future of NetMeeting • Microsoft plans to phase NetMeeting out and remove it from its Web site. The NetMeeting directory is already gone, which means that users have to type in the IP address of the person they want to conference with or use another online directory service. There is no time-frame for the NetMeeting phase-out. It appears that it will be a gradual transition. • Many businesses still use NetMeeting, although IM and Web conferencing products outclass it in terms of usability, analysts said.

  47. Future of NetMeeting • Before video service became common on free IM clients, such as Yahoo! Messenger and MSN Messenger, NetMeeting was a popular way to perform videoconferences and chatting over the Internet (with the help of public ILS servers, or "direct-dialing" to an IP address). • Since the release of Windows XP, Microsoft has deprecated it in favor of Windows Messenger and Microsoft Office Live Meeting, although it is still installed by default (Start : Run... : C:\Program Files\NetMeeting\conf.exe). Note that Windows Messenger, MSN Messenger and Windows Live Messenger hooks directly into NetMeeting for the application sharing, desktop sharing, and Whiteboard features exposed by each application.
