How can I link to my TeamSpeak 3 server on my webpage?

Complete format:

ts3server://ts3.hoster.com?port=9987&nickname=UserNickname&password=serverPassword&channel=MyDefaultChannel
&cid=channelID&channelpassword=defaultChannelPassword&token=TokenKey&addbookmark=MyBookMarkLabel 

Please keep in mind that if you use "cid=channelID", the parameter "channel=MyDefaultChannel" will be ignored.

Parameters are optional. In most cases specifying the host and port should be sufficient.
Nicknames usually should not be specified. Leave this to be configured by the users in the client.

So a common URL would look like this: ts3server://ts3.hoster.com?port=9987

Or simplified if only the port is given: ts3server://ts3.hoster.com:9987

Or even shorter, using default port 9987: ts3server://ts3.hoster.com
Example for a complete HTML link:

<a href="ts3server://ts3.hoster.com?port=9987">Click to connect to my server</a>

You can also use this feature to invite users to your server without having them to manually type the server-address.
