 In this mode users can connect more IRC networks, but they can't connect the network without being in the room. To connect the network, user has to join the room in following format: #room%irc.freenode.org@irc.domain.tld. The nickname used in the first join request is used as a nickname for the IRC connection.
 
+The port of IRC server can be also used, but it in that case, the Jabber ID of the room has to be encoded using [JID Escaping](http://www.xmpp.org/extensions/xep-0106.html). For example to join the IRC network on port 6697, you have to use following Jabber ID: #room\40irc.freenode.org\3a6697@irc.domain.tld.
