This article was previously published under Q303098 SUMMARYThis article describes how to configure Microsoft Exchange 2000 Conferencing Server and Microsoft Internet Security and Acceleration (ISA) Server 2000 to send and receive audio and video. First, you must configure a protocol rule to support the H.323 protocol, and then you must configure the H.323 Gatekeeper and Exchange 2000 Conferencing Server. You then must create a new protocol definition and a new server publishing rule in the ISA Server. Next, you configure destination sets, the ISA Server, and security settings. You then create Internet Protocol Packet filters and set the packet filtering properties. Finally, configure internal and external Microsoft NetMeeting clients and test the NetMeeting configuration. IN THIS TASKINTRODUCTION This step-by-step article describes how to configure
Exchange 2000 Conferencing Server and Internet Security and Acceleration (ISA)
Server 2000 so that participants can send and receive audio and video by using
the H.323 protocol. This article assumes that you have configured the
supporting networking infrastructure. Domain Name System (DNS), NetBIOS name
resolution, ISA Server clients and their network services, and network adapter
configuration parameters on the ISA Server must all be configured and
functioning correctly. back to the
topMORE INFORMATIONConfigure a protocol rule that supports the H.323 protocolYou must create a protocol rule to permit clients to access the
Internet through ISA Server by using the H.323 protocol. To create the H.323
protocol rule, follow these steps:
- Open the ISA Microsoft Management Console
(MMC).
- Expand Servers and Arrays.
- Expand the server or the array that you want to
configure.
- Expand Access Policy, right-click
Protocol Rules, and then click
New.

the topConfigure internal and external NetMeeting clientsThe internal and external Microsoft NetMeeting clients must be
configured separately. You have to register the internal NetMeeting clients
with the H.323 Gatekeeper, and you have to register the external NetMeeting
clients to use the external interface of the ISA Server as their
gateway. To configure internal NetMeeting clients, follow these steps:
- Click Start, point to
Programs, point to Accessories, point to
Communications, and then click
NetMeeting.
- On the Tools menu, click
Options.
- In the General tab, click
Advanced Calling.
- In the Advanced Calling Options window, click to select
the Use a gatekeeper to place calls check box.
- Type the IP address of the internal interface of the
ISA Server in the Gatekeeper box.
- Click to select the Log on using my phone
number check box, and then type a phone number in the Phone
number box.
- Click OK.
- On the Video tab, under
Sending and receiving video, click to select the
Automatically send video at the start of each call check
box.
- Click to select the Automatically receive video
at the start of each call check box.
- Click OK.
To configure external NetMeeting clients, follow these
steps:
- Click Start, point to
Programs, point to Accessories, point to
Communications, and then click
NetMeeting.
- On the Tools menu, click
Options.
- In the General tab, click
Advanced Calling.
- In the Advanced Calling Options window, click to select
the Use a gateway to call telephones and videoconferencing
systems check box.
- Type the IP address or the fully qualified domain name
(FQDN) of the external interface of the ISA Server.
- Click OK.
- On the Video tab, under
Sending and receiving video, click to select the
Automatically send video at the start of each call check
box.
- Click to select the Automatically receive video
at the start of each call check box.
- Click OK.
Note If the external client is behind a network address translation
(NAT) device, make sure that the NAT device supports the H.323
protocol. back to the
topTest the NetMeeting configurationAfter you configure the external NetMeeting client, the external
NetMeeting client can call an internal NetMeeting client by using the phone
number that is registered by the internal client with the gatekeeper. The
internal NetMeeting client has to accept the call to establish the
connection. After you test the NetMeeting configuration, remove the
gatekeeper settings from the internal client, and remove the gateway settings
from the external client. To remove gatekeeper settings from an internal
NetMeeting client, follow these steps:
- Click Start, point to
Programs, point to Accessories, point to
Communications, and then click
NetMeeting.
- On the Tools menu, click
Options.
- On the General tab, click
Advanced Calling.
- In the Advanced Calling Options window, click to clear
the Use a gatekeeper to place calls check box.
- Click OK two times.
To remove gateway settings from an external NetMeeting
client, follow these steps:
- Click Start, point to
Programs, point to Accessories, point to
Communications, and then click
NetMeeting.
- On the Tools menu, click
Options.
- In the General tab, click
Advanced Calling.
- In the Advanced Calling Options window, click to clear
the Use a gateway to call telephones and videoconferencing
systems check box.
- Click OK two times.
Note Exchange Conferencing Server does not require the gatekeeper and
the gateway settings for the NetMeeting clients. back to the topEdit the Netmeeting.js fileYou must edit the Netmeeting.js file to include the IP address of
your Exchange Conferencing Server computer and the phone number that you
included in the H.323 Gatekeeper configuration. The following is
default location of the Netmeeting.js file, where
version is the localized version that the clients
use: ProgramFiles\MicrosoftExchangeConferencing Server\Conferencing\version To edit the Netmeeting.js file, follow these steps:
- Open the Netmeeting.js file in Notepad, and then locate
the following line:
strCallTo = strMCUAddress+"+type=host+"; - Comment this entry by typing //
at the beginning of the line.
This change can help if you have to use
the original file structure for troubleshooting in the future. - Press ENTER to start a new line, and then type the
following line:
strCallTo = "1234+gateway=192.168.255.255+type=phone+"; In the line, replace 1234 with the
random number that you typed in the Phone box under
Static User Information during H.323 Gatekeeper configuration.
Replace 192.168.255.255 with the real IP address of
the Exchange Conferencing Server computer that you typed in the
Q931 address box. Note For the ISA Server to correctly proxy the traffic that transmits
from the Exchange Conferencing Server computer to the external client, the
computer that is running ISA Server and that handles the transaction must
either be in the default path that the traffic sends to the Internet, or the
Exchange Conferencing Server computer must have the Winsock proxy client
installed so that returning client traffic is processed by the computer that is
running ISA Server. In some cases, it is better to use a FQDN that
resolves to the ISA gateway externally and that resolves internally to the
Exchange Conferencing Server computer. The strCallTo variable works best if it is similar to the following: strCallTo = "1234567890+gateway=FQDN+type=phone+"; back to the
