SOE has posted the patch notes for Game Update 47 for EverQuest II, which integrates the Station Voice voicechat feature into the game.

HIGHLIGHTS

• Station Voice is now available!
• Equipment changes have been introduced to improve item progression from levels 1 – 59 worldwide.
• Check out the sections below for details on these highlights and other details of "Storm Break" (GU47).

LIVE EVENTS

• "Storm Break" (GU47): Librarian Feldarn of Freeport's Academy of Arcane Science and Librarian Dungil of Qeynos' Concordium are looking for volunteers to help battle the onslaught of darkness from beyond.
• Qeynos and Freeport have broken ground on major construction projects just off of the coast of Antonica and Commonlands respectively. Visit the docks to see the new activity!

STATION VOICE

• A new Voice Bar will appear that provides options and indicates who is currently speaking and when you're talking. It can be docked with any chat windows.
• A new Voice Users window will show all users in the current channel. This window can be changed to be transparent and show only active speakers if you'd like.
• Group and Raid windows have speaking indicators to show who is currently speaking.
• Voice options are available in the Options Menu under the "Voice Chat" tab.
• If you're not currently in a voice channel, you will be placed in the first channel that becomes available. Subsequent channels that become available can be selected through a dropdown on the Voice Users window, a button on the Voice Bar, or a link that appears in text chat.
• Left Control is the default push-to-talk key. You can change the key in the "Voice Chat" tab of the Options Menu.
• If you need more info, do "/help vchat" in game.
