Managing A/V Conferencing
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
With the A/V Conferencing Server users can conduct audio and video conversations with Office Communications Server 2007. During installation, the A/V Conferencing Server is configured with default settings. If you change the settings, ensure that the settings you choose do not conflict with settings for other Office Communications Server components that are running on the same computer. Configuring settings for an A/V Conferencing Server includes the following:
Configuring the Listening Address for A/V Conferencing Servers
Configuring Certificates for A/V Conferencing Servers
Configuring the Listening Address for A/V Conferencing Servers
To configure the listening address for A/V Conferencing Servers, you specify the following:
IP address for the listening address. The default is All, which is recommended if IP addresses in your environment are assigned dynamically or if your environment will use the FQDN to refer to the A/V Conferencing Server instead of an IP address.
Port on which the A/V Conferencing Server receives SIP signaling messages.
Range of media ports, from low to high, which the A/V Conferencing Server uses for Real-Time Transport (RTP) media. The default is 49152 to 65535. The low port can be any number from 49152 to 65535. The high port can also be any number from 49152 to 65535, but must be greater than the low port number by 23.
To configure the listening address for an A/V Conferencing Server
Open Office Communications Server 2007.
In the console tree, expand the forest node, and then do one of the following:
For an Enterprise pool, expand Enterprise pools, expand the pool, expand A/V Conferencing, right-click the A/V Conferencing Server that you want to configure, and then click Properties.
For a Standard Edition Server, expand Standard Edition servers, expand the pool, right-click the server, click Properties, and then click A/V Conferencing Properties.
Click the General tab.

On the General tab, under Settings, in the IP address drop-down list box, click the IP address that you want the A/V Conferencing Server to use. This is the address to which users connect for audio/video information and to which the A/V Edge Server connects. Any change to this setting will not take effect until you restart the Office Communications Server Audio/Video Conferencing service.
In SIP listening port, type the port number on which the A/V Conferencing Server listens for SIP traffic. Any change to this setting will not take effect until you restart the Office Communications Server Audio/Video Conferencing service.
In Media port range, type the lowest and highest port numbers of the port range that you want the A/V Edge Server and users to use to connect. The default is 49152 to 65535. The low port can be any number from 49152 to 65535. The high port can also be any number from 49152 to 65535, but must be greater than the low port number by 23.
Configuring Certificates for A/V Conferencing Servers
In a Standard Edition Server deployment or an Enterprise pool in a consolidated configuration, the A/V Conferencing Server, if deployed, is collocated with the Front End Server so the A/V Conferencing Server uses the certificate configured for the Front End Server. For an Enterprise pool in an expanded configuration, you must configure the certificate for the A/V Conferencing Server separately.
You should have set up this certificate using the Certificate Wizard when you deployed the Standard Edition Server or Enterprise pool. If you want to change the certificate, you can do either of the following:
You can use the Certificate Wizard to guide you through the process of requesting and assigning a certificate. (You can launch the Certificate Wizard from the Available tasks pane in Office Communications Server 2007 and in Computer Management for Standard Edition Servers. You can also access it from the Office Communications Server 2007 installation media).
If you want to assign a different certificate on an individual server, view a certificate, or delete a certificate, you can open the individual server's properties and configure the certificate using the Certificate tab. Deleting a certificate causes it to no longer be assigned to the server for TLS or MTLS, but the certificate is not deleted from the computer. The procedure in this section describes the use of the Certificate tab.
Any modifications you make are only applied to future connections—existing connections continue to use the old certificate as long as the connection continues.
To configure a certificate for an A/V Conferencing Server
Open Office Communications Server 2007.
In the console tree, expand the forest node, and then do one of the following:
For an Enterprise pool, expand Enterprise pools, expand the pool, expand A/V Conferencing, right-click the A/V Conferencing Server that you want to configure, and then click Properties.
For a Standard Edition Server, expand Standard Edition servers, right-click the server, click Properties, and then click A/V Conferencing Properties.
On the Certificate tab, do one of the following:
To delete a certificate, click the certificate, and then click Delete Certificate.
To assign a new certificate, click Select Certificate.
If any certificate setting on the new certificate other than the expiration date is different from the corresponding setting on the old certificate, restart the Office Communications Audio/Video Conferencing service for the change to take effect for all connections.
