What is Asterisk?

Asterisk is an open source, free soft switch/soft PBX system for managing all manner of telephony needs. The Eclipse Foundation is currently using it for a voice-conferencing solution.

The system was implemented in 2012 to reduce costs and offer greater flexibility.

How do I access it?


We have numbers in Canada, North America (toll-free), Germany, France, and the UK (toll-free). The European numbers are a local call anywhere in that country. Calling these numbers from any phone or VoIP phone will enable you to join a conference call. Your project or IWG leader will provide the number to call and passcode as part of the invitation to a meeting.


SIP is a popular VoIP protocol. We allow incoming SIP calls from around the world. These calls are free although they do require Internet access. To call an extension, you would use the following syntax in your SIP client:


(replace extension with the extension you wish to reach)

See a list of clients.

SIP clients we've used successfully:

  • Linux: twinkle - particularly good in that it doesn't require you authenticate against some system like many other clients. For anonymous calls into our conference system, authentication isn't needed.
  • Windows: X-Lite - pretty good. The one potential gotcha is that it want's to register against a system, so if you don't already have voip, you may need an account somewhere. Once you register, the calls to our system are free.
  • MacOS: TBD
  • Android: sipdroid
  • iPhone: TBD (check out 3cx or sipgate

We'll add some tips & hints for how to set up your client soon.

Conference commands

The following commands are available when connected to a conference call.

*1 to mute/unmute yourself
*2 lock/unlock the conference (moderator only)
*3 eject the last person to join (moderator only)
*4 decrease conference volume
*6 increase conference volume
*7 decrease your volume volume
*9 increase your volume volume

*8 exit the conference


Should you detect any issues with Asterisk, please raise a bug in Bugzilla to Eclipse Foundation => Community => Servers.
