Mozilla has a teleconferencing system we use for community meetings.

Dialing In

Normal phones (POTS)

If you have a Mozilla phone or softphone:

  • Please use it and dial 92 instead of dialing any of the below numbers.

From outside of Mozilla:

Beware of using "cheap international calls" deals - you may well get poor line quality and noise, which affects everyone on the call, not just you.

Dial any of these numbers:

  • US/California/San Francisco: +1 415 762 5700
  • US/California/Mountain View: +1 650 903 0800
  • US/Oregon/Portland: +1 971 544 8000
  • CA/BC/Vancouver: +1 778 785 1540
  • CA/ON/Toronto: +1 416 848 3114
  • DE/Berlin: +49 30 983 333 000
  • FR/Paris: +33 1 84 88 37 37
  • NZ/Auckland: +64 9 555 1100
  • UK/London: +44 (0)207 855 3000
  • US/Toll-free: +1 800 707 2533, password 369 (maximum 48 users at any one time)

Then, dial extension 92, and then "<conf_number> #". If you are calling in to a Vidyo meeting, dial "9 <vidyo_room_number> #". If the Vidyo room has a PIN, dial "9 <vidyo_room_number> * <PIN> #".

Internet calling (VoIP)

  • Most audio conference rooms have public SIP addresses like (or, for some clients, Replace the XXX with the conference room number. If it's a Vidyo room, use 9 and then the room number. Make sure you use direct-dial SIP rather than a via a provider account.
  • Gmail Chat works well and is free. You need to have Flash and Google Talk plugin installed. Just paste +1 650 903 0800 into the Gmail Chat box that doesn't look like it accepts phone numbers.
  • SkypeOut is free if you use the 800 number.
  • Mozilla employees can use VPN+SIP.

You could also set up your own SIP account with one of the many available providers, add credit and dial out to the phone system using that.

Attending A Meeting

Please mute yourself after joining, and at any time if you are not actively participating. All mobile phones and softphones, and some landline phones, have a mute button - use that for preference.

If you are using a phone without a mute button, or if you have a line noise problem on the normal phone system, then "*1" mutes and unmutes you at the Mozilla end. The trouble with this is that a) people can hear the 'beep', and b) you can forget to unmute because there is no visual indicator. Prefer mute buttons with obvious visual indicators, and get into the habit of checking them before speaking.


Learn how to use your software. Prefer VoIP clients (like Blink) which show latency and packet loss so you can tell easily when your connection is sucking. Consider making a test call to your provider's echo service first to make sure everything is working fine. Watch out for your microphone being muted in your OS settings.

Get a decent headset. If you are planning to participate using VoIP, never do so just using the microphone and speakers built into your laptop. You'll get poor sound quality, and everyone apart from you will get lots of echo too. (This is particularly bad, as you don't notice the problem, but everyone else does.) Get a decent headset. Mozilla IT recommends the Plantronics .Audio 646 DSP USB headset. You can get them for £19 ($25; €17) from various branches of Amazon, and they work on Windows, Mac and Linux. If you are a regular participant in Mozilla conference calls and £19 is more than you can afford, let us know and we'll get one for you.

Get a stable internet connection. Airport and hotel WiFi are often not good.

Volume controls

  • Pressing * by itself will give you an audio menu with the following:
  • *1 mute/unmute and exit the menu
  • *4/*6 make the conference quieter/louder to you (see below)
  • *7/*9 make yourself quieter/louder to everyone else (see below)

When dialing the volume controls, you remain in the menu. You can dial 4, 6, 7, or 9 repeatedly in any combination to adjust the volume in each direction. Please dial 8 once you get it to the volume level you want to exit the menu. If you forget to dial 8 it will eventually time out and tell you "Invalid Option"

Setting Up A Meeting

Picking a conference number

  • For Air Mozilla broadcasts, use 8600;
  • For meetings using Vidyo, use the Vidyo extension associated with the room;
  • Use your extension number (ie: 222, 223, ...); or
  • Borrow a number in the range 8601-8608 (ie: 8601, 8602, ...) for the duration of the meeting; or
  • File an IT Request (at least 24 hours in advance) requesting a new conference number.

Publicising your meeting

There is a conference template you can use on your wiki page, which automatically includes accurate dial-in information for your conference room. Add the following to your wiki markup, where 12345 is your conference number: {{conf|12345}}.

Conference settings

Mozilla employees can use the Asterisk web interface to manage settings such as password protection, mute-by-default, moderation (nobody can talk until the moderator arrives), entry beeps, and recording. You can also view and manage the current inhabitants of your conference room.

Moderator controls

  • *2 - lock/unlock the room
  • *3 - eject the last person to enter
  • *81 - Roll call or user count
  • *82 - Eject all non-admins
  • *83 - Mute/unmute all non-admins

Inviting participants

  • On the wiki page for your meeting, write e.g. {{conf|225}} to include instructions with the "California" and "US toll-free" phone numbers, along with a link to this page. (Example)
  • Consider including an Etherpad URL for notetaking, an IRC backchannel, and a physical location in one or more offices.
  • Be sure to specify the time zone in your messages. For recurring meetings, the Mozilla standard is to fix the time in the US Pacific Timezone, rather than in UTC.
  • Mozilla employees can use Zimbra to find out when invitees are free, send invitations, and book a conference room.


Help! Where's that noise coming from?


  • If a speaker has an echo, someone else is causing it by not being muted (usually because they're not using a headset, and their built-in mike is picking up the speaker output). Don't blame the speaker.
  • If there is background noise, someone is not muted.
  • If there's some weird feedback noise, it's probably because someone is not using a headset and is not muted.


  • Say "Everyone please press *1 to mute" in an increasingly desperate tone of voice.
  • The moderator can press *83 to mute everyone.
  • Ask for help in #servicedesk. The Service Desk staff can find out which participant is bringing the noise and mute them.
