Deploying
IBM® Sametime® consists of a variety of servers and clients, and can be deployed to suit many different environments. The deployment instructions are organized by feature set, beginning with the minimum components that are necessary to support instant messaging, and then expanding the deployment to include features such as audio and video support, and conferencing.
Deploying audio and video
Audio and video features are provided primarily by the IBM® Sametime® Media Manager, which supports point-to-point and multipoint calls. The Sametime Media Manager uses standard audio and video codecs so that it works with products from other audio and video vendors.
Installing the Sametime® TURN Server
The IBM® Sametime® TURN Server enables Sametime clients to send audio and video communications across a NAT (Network Address Translator) or firewall when direct peer-to-peer communications are not possible. The Sametime TURN Server is available for installing on the Linux™ or Windows™ platforms only. Read the system requirements to ensure that you know the minimum supported software requirements.
Configuring firewalls and opening ports
If the IBM® Sametime® TURN Server and the Sametime Media Manager are separated from clients by firewalls, you must open ports in the firewalls to enable communications.

Configuring firewalls and opening ports

If the IBM® Sametime® TURN Server and the Sametime Media Manager are separated from clients by firewalls, you must open ports in the firewalls to enable communications.

Before you begin

You only need to complete this task when there is direct UDP communication between intranet clients and the Sametime Video MCU server (with no network address translation).

About this task

Use the information in TURN Server ports to help you determine which ports need to be opened.

Procedure

Set the DNS rules for intranet clients to ensure that they can resolve the TURN Server host name to "0.0.0.0".
This optimizes the use of the TURN Server when a deployment includes a large number of clients that can directly access the Sametime Video MCU.
Make sure that all extranet clients (including Internet users) can resolve the TURN Server host to the real IP address.
