Call admin with teamspeak?

For the basic [lexicon='ts3',''][/lexicon] configuration you should take a look here: TeamSpeak 3
The documentation for the report plugin isn't written, yet. So here a short version:

Take a look into the config/plugins/reports.json file.

A possible version for [lexicon='ts3',''][/lexicon] could look like this:

{
    "reports": {
        "enabled": true,
        "database": false,
        "decaytime": 180,
        "logfile": false,
        "mail": false,
        "mailmessage": "The player '<FROM>' just reported '<TARGET>' with the following message: <MESSAGE>",
        "mailrecipients": [],
        "mailsubject": "GSManager Report",
        "ts3poke": true,
        "ts3pokemessage": "GSManager: '<FROM>' reported '<TARGET>': <MESSAGE>",
        "ts3pokeuids": ["iytBus+itdc2u6u33ciPLIhiQ/M=", "asdfasdfasdfasdfasdf/M="],
        "ts3text": true,
        "ts3textmessage": "GSManager: '<FROM>' reported '<TARGET>': <MESSAGE>",
        "ts3textuids": ["auianiuand/asdasd/O=", "iboiugb97978sdf/M="]
    }
}

Line 3: Enable the plugin.
Line 5: Timeout between two reports from the same player.
Line 11: Enable if you want to get poked.

Line 12: With this message you will get poked.
Line 13: The UIDs of the [lexicon='TS3',''][/lexicon] users you want to poke. If you have only one then it looks like this: "ts3pokeuids: ["iytBus+itdc2u6u33ciPLIhiQ/M="],
Line 14-16: Same like the lines 11-13 put not for poke but for private text messages within [lexicon='TS3',''][/lexicon].
Line 16 (caution!): No comma at the end of the line
