IBM Lotus Sametime 7.5.1 Release Notes

Sametime Gateway

Sametime capabilities are limited with external users

The Sametime Gateway supports awareness and instant messaging with external communities. Other Sametime features, such as file transfer, n-way chat, and voice-chat are not available with external users. Some options, such as rich text, are disabled when chatting with an external user. If a user tries to send an emoticon, it is converted to a text symbol, such as :-).

Sametime Gateway

Sametime Gateway has limited NAT support

Network Address Translation (NAT) is supported between local Sametime community servers and Sametime Gateway 7.5.1, but NAT is not supported between Sametime Gateway and the Internet, because of a limitation in the SIP protocol.

A NAT-enabled firewall does not work with some Internet protocols, including the SIP protocol, which Sametime Gateway uses to exchange messages with AOL Instant Messenger™, Yahoo! Messenger, and other Sametime communities. However, NAT has no affect on the XMPP protocol, so exchanges using Google Talk over XMPP would be permitted to pass through a NAT-enabled firewall that is between Sametime Gateway and the Internet.

Sametime Gateway

Sametime servers 3.0, 6.5.1, and 7.0 require a SIP patch

Sametime servers 3.0, 6.5.1, and 7.0 require a SIP patch to connect to Sametime Gateway. A patch is available from Lotus Support, so you can successfully connect Sametime Gateway to external Sametime 3.1, 6.5.1, or 7.0 servers. These patches need to be applied to older Sametime servers in external communities.

Sametime Gateway

XMPP does not support Sametime Gateway clusters

You cannot use the XMPP translation protocol to connect to a Google Talk community over a Sametime Gateway cluster. Use a single Sametime Gateway server if you want to set up a connection with the Google Talk community.
