A telephone system for your World of Warcraft guild.
Every member gets an extension. Dial five digits to reach a guildmate, eight to join a raid room. Nobody misses a call: there is voicemail, and the lamp on the handset lights up when a message is waiting.
It works with a real SIP desk phone - the kind you can buy used for the price of a month's game time - or with a softphone if you would rather not have a telephone on your desk.
Not in a guild yet? Sign in anyway - you get a number and a mailbox in the public pool, and you keep them when you join one.
Get the in-game addon — everyone needs it. Claiming a character means exporting from it in game, and there is no other route yet.
Everything we keep, and why calls are never recorded, is on the privacy and security page.
